BAS4005E6327HTSA1 Descripción general
A Schottky diode is a majority-carrier semiconductor device formed by a metal-semiconductor junction rather than the PN junction used in conventional diodes. This construction eliminates minority-carrier charge storage, which is why Schottky diodes switch far faster than silicon rectifier diodes and exhibit a lower forward voltage drop (typically 0.3-0.5 V at low current). The trade-off is a higher reverse leakage current and a lower maximum reverse-voltage rating, which is why Schottky diodes are typically deployed in low-voltage, high-speed signal paths and DC-DC converters rather than in mains rectification. The BAS4005 series sits in the hierarchy Schottky diode -> rectifier diode -> discrete semiconductor -> electronic component.
Key features of the BAS4005E6327HTSA1 include a 40 V repetitive peak reverse voltage (VRRM), a 120 mA average forward current (IF(AV)), a very low reverse recovery time suited to multi-MHz switching, and compliance with AEC-Q101 automotive qualification. The common-cathode configuration in the SOT-23 footprint provides two independent Schottky junctions sharing a single cathode pin, enabling OR-ing, voltage clamping, or full-wave rectification in a compact 3-pin outline.
The device is intended for general-purpose rectification, signal demodulation, high-speed switching, voltage clamping, high-level detecting, and mixing in both consumer and automotive designs. Its low forward voltage preserves signal margin in low-voltage analog circuits and protects downstream ICs from inductive kickback.
When designing with this part, observe the thermal derating shown on the IF = f(TS) curve: at 120 mA the allowed solder-point temperature limits the practical ambient temperature range, and the SOT-23 thermal resistance of approximately 357 C/W on a minimal pad means substantial copper area is required at higher duty cycles.

Aplicaciones típicas
BAS4005E6327HTSA1 es adecuado para 6 aplicacións: 12V/24V Automotive Load-Dump Protection, Signal Demodulation and Mixing, High-Speed Switching in DC-DC Converters, USB Data-Line ESD / Voltage Clamping, Battery Charger Reverse-Polarity Protection, Industrial Sensor Signal Conditioning.
12V/24V Automotive Load-Dump Protection
The BAS4005E6327HTSA1 is well suited as a steering / clamping diode in 12 V and 24 V automotive load-dump protection networks, where its 40 V reverse-voltage rating provides adequate headroom above the maximum load-dump transient specified by ISO 7637-2. The common-cathode configuration allows two parallel steering paths to a single ground-return TVS or shunt, simplifying PCB layout. AEC-Q101 qualification confirms reliability across the -40 C to +125 C automotive Grade-1 temperature range, and the 120 mA rating covers pilot-signal and low-current rail-monitoring paths. The SOT-23 footprint keeps the protection network compact near the connector.
Recomendado
Signal Demodulation and Mixing
For low-frequency signal demodulation and small-signal mixing, the BAS4005E6327HTSA1's majority-carrier Schottky construction yields negligible reverse-recovery charge and very low turn-on voltage. This preserves linearity in AM demodulators and RF detector circuits operating from a few kHz up to tens of MHz. The common-cathode configuration supports full-wave detector topologies where two antiparallel diodes share a common cathode feed to the load. The SOT-23-3 (PG-SOT23) outline allows the part to sit adjacent to the IF coil or detector transformer without disturbing the RF ground path.
Recomendado
High-Speed Switching in DC-DC Converters
In low-power buck and boost converters, the BAS4005E6327HTSA1 functions as a synchronous-rectifier or free-wheeling diode, where its low forward-voltage drop (approximately 1 V at 100 mA) minimizes conduction loss and its near-zero reverse-recovery time eliminates the switching losses that plague PN-junction rectifiers above 1 MHz. The common-cathode pair supports dual-phase rectification in a single SOT-23 footprint, halving board area versus two discrete diodes. AEC-Q101 qualification suits the part for automotive POL converters and industrial isolated DC-DC modules.
Recomendado
USB Data-Line ESD / Voltage Clamping
The BAS4005E6327HTSA1 is useful as a low-capacitance clamping element on USB 2.0 data lines and other low-speed logic interfaces where the 40 V reverse standoff safely exceeds the 5 V Vbus level and the fast switching edge limits ESD-induced ringing. The common-cathode dual allows the designer to clamp both D+ and D- to a single ground return, saving one PCB trace versus discrete single diodes. The SOT-23-3 (PG-SOT23) outline drops directly onto the standard USB footprint, and AEC-Q101 qualification permits use in automotive USB charging ports.
Recomendado
Battery Charger Reverse-Polarity Protection
In single-cell Li-ion and multi-cell NiMH charger front-ends, the BAS4005E6327HTSA1 provides reverse-polarity protection in series with the battery rail. Two common-cathode diodes OR two input sources (USB and adapter) into one charger input, while the low forward drop of approximately 1 V at 100 mA keeps charger dissipation under 100 mW. AEC-Q101 qualification supports automotive 12 V accessory chargers and industrial backup-battery systems. The SOT-23-3 footprint enables compact wearable and IoT charger PCB layouts.
Recomendado
Industrial Sensor Signal Conditioning
In industrial 4-20 mA current-loop sensor interfaces and PLC digital-input modules, the BAS4005E6327HTSA1 serves as a half-wave rectifier for low-level AC sensor signals or as a free-wheeling clamp across relay coils and solenoids. The 40 V rating tolerates 24 V industrial rails with margin, the 120 mA forward current handles typical PLC input currents, and AEC-Q101 plus the wide -55 C to +150 C junction range ensures robust operation in factory environments. The SOT-23-3 footprint supports dense channel-per-inch input modules.

Notas de diseño
Estimated: at 120 mA continuous forward current and a typical SOT-23 theta_JA of 357 C/W on a JEDEC EIA/JESD51 1-oz 2-layer test board, the junction-to-ambient thermal rise is approximately 43 C per 120 mW of dissipation. For applications near the full 120 mA rating, lay at least 25 mm^2 of 1-oz copper on both top and bottom layers under pin 3 (cathode) to reduce theta_JA by roughly 50 percent, and derate IF proportionally to keep TJ below 150 C.
Keep the SOT-23-3 cathode (pin 3) land area as large as practical and stitch it directly to the system ground plane with multiple vias. Because the common-cathode pair returns both diode currents through pin 3, inductance in that path will generate switching transients that defeat the diode's low reverse-recovery advantage. Place input traces short and direct, and avoid routing sensitive analog signals beneath the SOT-23 footprint.
Do not use the BAS4005E6327HTSA1 as a reverse-polarity blocker in series with high-current loads: its 120 mA IF rating will saturate and the part will fail short. For full reverse-polarity protection use a P-channel MOSFET in the positive rail, and use the BAS4005 only for low-current OR-ing, clamping, or signal-level rectification. Also observe that the typical VF around 1 V at 100 mA means a single diode drops nearly 10 percent of a 12 V rail - cascade two for symmetric AC applications.
