CAP014DG-TL Présentation
What is an X capacitor discharge IC? An X capacitor (across-the-line safety capacitor) requires a discharge path when AC mains is removed to meet safety standards such as IEC 62368-1. Traditional discharge resistors waste several milliwatts continuously, reducing standby efficiency. An X capacitor discharge IC replaces these resistors with a smart switch that blocks current during normal operation and engages discharge resistors when AC is disconnected - eliminating standby loss while maintaining safety compliance.
Key features include 1000V peak voltage rating, support for up to 1000 nF X capacitors, ultra-low standby power of less than 5 mW at 230 VAC, automatic discharge activation when AC is removed, and compatibility with converter/ACDC applications across the 80 VAC to 265 VAC universal input range. The 8-SOIC package enables easy integration into existing flyback, buck, or other AC-DC converter layouts with minimal PCB area.
The CAP014DG-TL uses two back-to-back high-voltage MOSFETs with intelligent sensing to detect AC presence. When AC voltage is applied, the internal switches are off and no current flows through the discharge resistors. When AC is removed, the IC detects the absence and closes the switches, allowing the discharge resistors to safely bleed the X capacitor voltage below the 34V safety threshold within one second as required by safety standards.
Typical applications include adapters and chargers for consumer electronics, smart home and IoT devices, standby power supplies in white goods, ultra-low standby power AC-DC converters, and USB-PD power adapters. The device is particularly valuable in designs targeting Energy Star and EU Ecodesign standby limits below 500 mW.
When designing with this device, pair the CAP014DG-TL with a matched X capacitor whose value does not exceed 1000 nF. Ensure trace spacing on the high-voltage pins complies with IEC 62368-1 creepage and clearance requirements. Confirm that the total discharge time meets the safety standard in your target region.

Applications typiques
CAP014DG-TL convient pour 7 applications: USB-PD Adapters and Travel Chargers, Smart Home and IoT Power Supplies, White Goods Standby Supplies, Ultra-Low Standby AC-DC Converters, Audio Amplifier and Set-Top Box Power Supplies, LED Driver Standby Rails, Industrial Auxiliary Supplies.
USB-PD Adapters and Travel Chargers
The CAP014DG-TL is well-matched to USB-PD adapters rated 30 W to 100 W where standby loss must remain below 100 mW to qualify for Energy Star and EU 2023 Ecodesign. Its 1000 nF X capacitor support accommodates the bulk X capacitance typically used to filter common-mode noise in high-power PD converters. The IC reduces standby power to under 5 mW at 230 VAC, helping meet regional efficiency standards. The 8-SOIC footprint slots directly onto AC front-end daughter cards.

Smart Home and IoT Power Supplies
Smart home hubs, Wi-Fi routers, and always-on IoT gateways need standby consumption below 500 mW. The CAP014DG-TL's automatic discharge function eliminates the continuous loss of bleed resistors while preserving IEC 62368-1 X-capacitor discharge compliance. Designers can use a larger X capacitor for better EMI filtering without violating standby budgets. The 1000 V rating covers universal 80 to 265 VAC input and global OVP transients. Compact 8-SOIC packaging fits wall-wart and outlet form factors.
Recommandé
White Goods Standby Supplies
Refrigerators, washing machines, and dishwashers need standby rails that consume under 100 mW to satisfy EU 2021 standby regulation. The CAP014DG-TL's sub-5 mW standby enables ultra-low standby overall budgets when paired with a CAPZero or InnoSwitch flyback primary. The IC pairs naturally with Power Integrations' LinkSwitch-XT family. Universal 80 to 265 VAC compatibility simplifies global SKU consolidation.
Recommandé
Ultra-Low Standby AC-DC Converters
Designing an AC-DC flyback with standby below 30 mW at 230 VAC is impractical with discrete 1.5 megohm bleed resistors. The CAP014DG-TL replaces the bleeder network with a smart switch that engages only when AC is removed, eliminating steady-state drain. Up to 1000 nF capacitance gives designers flexibility to balance EMI filtering and discharge time constants. The 8-SOIC enables low-profile packaging for ultra-thin designs.
Recommandé
Audio Amplifier and Set-Top Box Power Supplies
Soundbars, AV receivers, and set-top boxes often have mandatory standby entries after a few hours of inactivity. The CAP014DG-TL minimizes standby consumption while keeping audio rails ready for fast wake. Its 1000 V rating tolerates surge events on the AC input, and the 8-SOIC package boards cleanly alongside PFC inductors. Designers can use a larger X capacitor to reduce common-mode noise coupled into analog stages.
Recommandé
LED Driver Standby Rails
Connected LED drivers and smart luminaires often remain powered at all times for wireless control. The CAP014DG-TL allows a smaller standby bias supply by eliminating bleeder-resistor loss. The 1000 V breakdown voltage handles universal mains and over-voltage transients, while the 8-SOIC package co-locates with PFC and flyback stages. This supports Dim-to-Off and standby operation needed for Title 24 and EU lighting regulations.
Recommandé
Industrial Auxiliary Supplies
Industrial PLCs, sensor hubs, and machine controllers require reliable standby for network keep-alive. The CAP014DG-TL delivers robust 1000 V isolation and supports the universal 80 to 265 VAC range typical of factory mains. Pairing with Power Integrations' InnoSwitch or LinkSwitch primary gives a complete auxiliary supply. The 8-SOIC ships in tape and reel for high-throughput SMT production.

Principaux différenciateurs
- Highest X capacitance support in the 1000 V class of CAPZero family (vs CAP012DG-TL)
- Back-to-back high-voltage MOSFET topology eliminates bleeder-resistor standby loss (vs Discrete 1.5 Mohm discharge resistors)
- Universal AC input compatibility within the same part number (vs Region-specific discharge ICs)
Notes de conception
Do not exceed the 1000 nF maximum X capacitance rating. Exceeding this limit risks incomplete discharge within the IEC 62368-1 one-second time limit. The CAP014DG-TL only engages discharge resistors when AC is removed, so a defective or absent AC sense path can leave X capacitors charged. Verify AC presence with the appropriate sense divider before finalizing the BOM. Estimated: this guidance is based on the manufacturer's CAPZero family operating principle, not a specific datasheet figure.
Maintain creepage and clearance distances on the high-voltage pins per IEC 62368-1. The 1000 V breakdown rating demands at least 2.5 mm clearance on 230 VAC systems, more for pollution degree 2 environments. Place the IC away from low-voltage signal traces to minimize coupling. Use a grounded copper shield under the high-voltage section if the layout is dense.
Keep the trace between the IC and the X capacitor short to reduce parasitic inductance. Locate the external discharge resistors close to the IC's R1 and R2 pins to minimize trace length. Avoid routing noisy switching nodes near the AC sense pins. A 100 nF ceramic bypass close to the VS pin improves noise immunity during discharge events.
Under normal operation the CAP014DG-TL dissipates less than 5 mW and requires no heatsink. However, surge events on the AC line can briefly increase dissipation. Ensure the PCB copper pour connected to the high-voltage pins is sized for the worst-case surge current. Estimated: thermal rise at 5 mW continuous is negligible at the 8-SOIC's 200 C/W theta_JA.
