TPD1E10B09DPYT Обзор
A TVS diode is a discrete transient-voltage-suppression device that diverts ESD energy away from sensitive circuitry. TVS protection devices sit at connector entry points, interface lines, and exposed external ports, where electrostatic discharge can otherwise damage low-voltage integrated circuits. The TPD1E10B09 family combines low capacitance with IEC 61000-4-2 level 4 contact and air-gap ESD protection, making it appropriate for compact consumer, industrial, and communications equipment.
The TPD1E10B09DPYT provides plus-or-minus 9 V ESD protection, a 20 V clamp voltage, 4.5 A peak pulse current, and 10 pF line capacitance. Its back-to-back TVS structure supports bipolar or bidirectional signal operation. The 0402 package is approximately 1.0 mm by 0.5 mm and is intended for space-constrained boards where protection must be added without materially increasing placement area.
Use this device near the connector or entry point of the protected signal rather than deep inside the PCB, where the ESD path becomes longer and inductance can reduce clamping performance. Keep the protected trace short, provide a low-impedance return path, and place the device on the same side of the board as the connector when practical. The protection device should be selected together with the signal's voltage tolerance, bandwidth, and connector geometry.
Typical uses include USB, headphone, control, sensor, and other compact serial interfaces exposed to user contact. For high-speed lines, verify that the 10 pF capacitance does not create unacceptable signal attenuation or edge-rate degradation. The device is not intended as a surge protector for sustained overvoltage or power transients beyond the specified ESD test conditions.
This page combines verified manufacturer and distributor information with practical ESD-layout guidance. Verify the final footprint, polarity, working voltage, clamp behavior, and system-level ESD immunity on the assembled design before production.

Типичное применение
TPD1E10B09DPYT подходит для 6 применениеs: USB Interface Protection, Headphone and Audio Interface, Sensor and Control Port ESD Protection, Compact Industrial Control Module, Portable and Wearable Device Port, Low-Voltage Serial Communication Line.
USB Interface Protection
The TPD1E10B09DPYT is useful for protecting compact USB-facing signal lines that are exposed to user contact or cable ESD. Its single-channel 0402 package preserves board area, while the 10 pF line capacitance limits additional loading on high-speed transitions. Place it close to the connector entry point, with the protected trace routed directly toward the receiver. The device is rated for ±20 kV IEC 61000-4-2 level 4 contact and air-gap protection, but the final USB design must still satisfy the applicable interface, impedance, and system-level ESD requirements.
Рекомендуется
Headphone and Audio Interface
For headphone, microphone, and other low-voltage audio interfaces, the TPD1E10B09DPYT provides ESD diversion in a very small footprint. Its 10 pF capacitance can be useful on lines where excessive loading would affect signal transitions, although the exact audio bandwidth and impedance must still be checked. The bidirectional back-to-back structure supports positive or negative signal excursions. Place the diode close to the external connector and keep the return path short so the ESD pulse reaches the protection device before it reaches sensitive audio circuitry.
Рекомендуется
Sensor and Control Port ESD Protection
The TPD1E10B09DPYT is appropriate for compact sensor, control, and general-purpose I/O ports where an exposed connector can receive electrostatic discharge. Its ±9 V ESD protection and 20 V clamp target low-voltage interface protection, while its 0402 package allows protection to be added close to the connector without occupying a large board region. Validate the protected signal's normal voltage range, polarity, and leakage requirements against the complete external cable and equipment environment. The diode should supplement, not replace, normal overvoltage and surge protection.
Рекомендуется
Compact Industrial Control Module
In a small industrial control module, the TPD1E10B09DPYT can protect a low-voltage external command or status line from ESD events while conserving board area. The 20 V clamp and 4.5 A 8/20-microsecond pulse rating provide a defined transient response, and the 10 pF capacitance helps limit loading on digital or slow analog signals. The device should be positioned at the enclosure or connector boundary, with a short return connection and controlled routing. Industrial qualification, operating temperature, and system immunity requirements remain application-specific and are not supplied by the verified search data.
Рекомендуется
Portable and Wearable Device Port
The TPD1E10B09DPYT is well suited to portable and wearable products where a small connector or exposed touch/control interface requires ESD protection with minimal board footprint. Its 0402 2-X1SON package is convenient for dense layouts, and its 10 pF capacitance is comparatively low for a protection diode. The protection element should be placed directly at the entry point, with the protected net routed away from sensitive analog or radio circuitry. Final qualification should include mechanical cable movement, human-body contact, and the product's complete enclosure and charging environment.
Рекомендуется
Low-Voltage Serial Communication Line
TPD1E10B09DPYT can be placed on a low-voltage serial or control communication line where ESD transients may enter through an external cable. The single-channel, bidirectional configuration supports signal polarity variations, and the 20 V clamp is intended to limit stress on downstream circuitry. Confirm that the line's normal operating voltage, data rate, ground reference, and connector exposure remain within the device's specified operating conditions. In high-speed designs, measure edge degradation and channel attenuation after adding the 10 pF protection capacitance.

Заметки по проектированию
Place the TPD1E10B09DPYT at the PCB boundary facing the connector or user-accessible port. Keep the ESD path from the connector pad to the protection diode as short as practical, and provide a nearby low-impedance return connection. A long trace adds parasitic inductance and can reduce effective clamping during a fast ESD event. For differential or high-speed pairs, place the protection components consistently on the same PCB side and preserve the intended return-path geometry.
Account for the specified 10 pF line capacitance when the protected signal is not a low-frequency control line. Capacitive loading increases with data rate and can slow edges, reduce signal amplitude, or disturb impedance-controlled routing. Validate with the actual connector, receiver, trace length, and termination network. If the interface is especially fast, compare the complete channel response with and without the diode before releasing the layout.
Do not treat the TPD1E10B09DPYT as a complete surge-protection solution for sustained overvoltage, lightning, or industrial transients. The verified information describes ESD protection and an 8/20-microsecond pulse rating, not unlimited power handling. Confirm the normal signal voltage, polarity, cable length, grounding arrangement, and required system immunity before relying on the device as the sole protection element.
