Product details
Overview
P4KE180CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 154 V standoff voltage (VWM), 171–189 V breakdown range (VBR at 1 mA), 246 V clamping voltage (VC) at 1.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines, industrial I/O ports, and DC power rails.
For engineers reviewing the P4KE180CHE3/54 datasheet, P4KE180CHE3/54 pinout, P4KE180CHE3/54 application, or P4KE180CHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, glass-passivated junction, low incremental surge resistance, and compatibility with manual or wave soldering per J-STD-002 - critical for high-reliability embedded power and interface protection designs.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation, it avalanches sharply at VBR to limit transient overvoltages. Its glass-passivated junction ensures stable leakage and repeatable breakdown behavior across temperature (-55 °C to +175 °C).
It delivers 400 W peak pulse power handling with 10/1000 μs waveform at 0.01% duty cycle, supported by a thermal resistance of 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient), enabling effective heat dissipation in compact PCB layouts without heatsinking.
Key Specifications

FAQ
What is the clamping voltage of P4KE180CHE3/54 and how does it protect downstream circuits?
The P4KE180CHE3/54 has a maximum clamping voltage (VC) of 246 V at 1.6 A peak pulse current (10/1000 μs waveform). This means that during a transient event, the device limits the voltage seen by protected components to ≤246 V, preventing overvoltage damage to ICs, transceivers, or sensors connected to the same line. Its low incremental surge resistance ensures minimal overshoot, making P4KE180CHE3/54 effective for IEC 61000-4-5 Level 3/4 surge immunity.
Is P4KE180CHE3/54 suitable for automotive applications?
Yes, P4KE180CHE3/54 is AEC-Q101 qualified and carries the HE3 suffix indicating compliance with automotive stress tests including high-temperature operating life, temperature cycling, and ESD-HBM ≥ 8 kV. It is rated for operation from -55 °C to +175 °C and is widely used in engine control units, ADAS sensor interfaces, and body electronics where load dump and ISO 7637-2 transients must be suppressed - confirming P4KE180CHE3/54 as an automotive-grade solution.
What does the "HE3" suffix mean in P4KE180CHE3/54?
The "HE3" suffix in P4KE180CHE3/54 indicates two key attributes: RoHS compliance and AEC-Q101 qualification. Specifically, HE3 denotes JESD 201 Class 2 whisker resistance, full automotive reliability testing, and traceable manufacturing per automotive standards. This distinguishes P4KE180CHE3/54 from the commercial-grade P4KE180A-E3/54 (E3 only), making P4KE180CHE3/54 mandatory for OEM automotive programs requiring certified qualification.
Can P4KE180CHE3/54 be used in bidirectional configurations?
No, P4KE180CHE3/54 is a unidirectional TVS diode, as confirmed by its part number ending in "A" (not "CA"). Bidirectional variants like P4KE180CA exist for AC-line or symmetrical transient protection, but P4KE180CHE3/54 is polarity-sensitive and must be installed with the cathode toward the protected line and anode to ground. Using P4KE180CHE3/54 in bidirectional circuits would result in forward conduction during negative transients and failure to clamp.
What is the thermal resistance and power derating behavior of P4KE180CHE3/54?
P4KE180CHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient (RθJA) of 100 °C/W with 10 mm lead length. Its steady-state power dissipation (PD) is 1.5 W at TL = 75 °C, derating linearly to zero at 175 °C. For pulsed operation, it sustains 400 W peak power at 0.01% duty cycle - meaning P4KE180CHE3/54 requires no heatsink in typical PCB layouts but benefits from copper pour under leads for sustained surge repetition.
