Product details
Overview
P4KE180CHE3/73 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 stand-off voltage (VWM), 171–189 V breakdown range (VBR at 1 mA), 246 V maximum clamping voltage (VC) at 1.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform. It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the P4KE180CHE3/73 datasheet, P4KE180CHE3/73 pinout, P4KE180CHE3/73 application, or P4KE180CHE3/73 equivalent, key selection criteria include clamping voltage margin relative to protected circuit's absolute maximum rating, junction temperature derating above 25 °C, lead-free RoHS compliance with AEC-Q101 qualification, and DO-41 mechanical compatibility with legacy through-hole layouts.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its specified breakdown range. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the DO-41 package provides thermal resistance of 100 °C/W (junction-to-ambient) and 66 °C/W (junction-to-lead).
It sustains 40 A non-repetitive forward surge current (8.3 ms half-sine), dissipates 1.5 W continuously on infinite heatsink at 75 °C lead temperature, and exhibits 0.108 %/°C temperature coefficient of VBR. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Surface-mount SMB package (vs. through-hole DO-41); same 180 V nominal breakdown, but 600 W PPPM. | Requires PCB rework for SMT layout; better suited for space-constrained designs with automated assembly. | Select SMBJ180A when board real estate is limited and SMT process is established; verify thermal pad design for 600 W dissipation. |
| 1.5KE180A | Same DO-41 package but higher 1.5 kW PPPM; VC = 259 V at 6.1 A, wider VBR tolerance (171–189 V → 171–209 V). | Higher energy handling for severe surge environments (e.g., utility metering), but larger VC margin may compromise protection of low-voltage ICs. | Choose 1.5KE180A only if system-level surge testing requires >400 W capability; confirm protected ICs tolerate 259 V clamping. |
Compared with P4KE180CHE3/73, SMBJ180A offers higher power density in SMT form but lacks AEC-Q101 qualification, while 1.5KE180A delivers greater surge capacity at the cost of reduced clamping precision and no automotive qualification-making P4KE180CHE3/73 optimal for cost-sensitive, AEC-Q101–mandated automotive and industrial through-hole designs.

FAQ
What is the clamping voltage of P4KE180CHE3/73 and how does it protect downstream components?
The P4KE180CHE3/73 has a maximum clamping voltage (VC) of 246 V at 1.6 A peak pulse current (10/1000 μs). This value represents the highest voltage that appears across the device during a transient event, limiting stress on protected ICs or MOSFETs. Because P4KE180CHE3/73 clamps reliably below typical 28 V or 36 V absolute maximum ratings of many power management ICs, it prevents overvoltage damage while maintaining functional integrity of the host circuit.
Is P4KE180CHE3/73 suitable for automotive applications?
Yes, P4KE180CHE3/73 is AEC-Q101 qualified (confirmed by the HE3 suffix), making it suitable for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces. Its 175 °C maximum junction temperature, glass-passivated junction, and validated reliability under thermal cycling and humidity testing meet stringent automotive requirements-unlike commercial-grade variants such as P4KE180A-E3.
How does the DO-41 package of P4KE180CHE3/73 affect thermal performance?
The DO-41 package of P4KE180CHE3/73 delivers a junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 66 °C/W. This means effective heat dissipation relies on adequate copper pour and lead length; for continuous 1.5 W operation, lead temperature must be held ≤75 °C. In practice, P4KE180CHE3/73 is optimized for transient (not steady-state) power handling, so thermal design focuses on pulse energy absorption rather than DC thermal management.
What is the significance of the HE3 suffix in P4KE180CHE3/73?
The HE3 suffix in P4KE180CHE3/73 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike the E3 suffix (commercial grade only), HE3 certifies that P4KE180CHE3/73 has passed automotive-specific stress tests including temperature cycling, highly accelerated life testing (HALT), and mechanical shock-ensuring long-term reliability in harsh vehicular environments where P4KE180CHE3/73 is deployed.
Can P4KE180CHE3/73 be used in bidirectional protection circuits?
No, P4KE180CHE3/73 is a unidirectional TVS diode, identifiable by its cathode band marking and specification table listing only unidirectional parameters (e.g., IFSM, VF). For bidirectional protection, Vishay specifies CA-suffix parts like P4KE180CA. Using P4KE180CHE3/73 in bidirectional configurations risks forward conduction during negative transients, potentially damaging the device or failing to suppress the surge-so P4KE180CHE3/73 must be applied only in polarity-aware, unidirectional layouts.
