Product details
Overview
P4KE180CAHE3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 154 V standoff voltage (VWM), 171–189 V breakdown range (VBR) at 1 mA, 246 V maximum clamping voltage at 1.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE180CAHE3/54 datasheet, P4KE180CAHE3/54 pinout, P4KE180CAHE3/54 application, or P4KE180CAHE3/54 equivalent, this device is selected for automotive-grade overvoltage protection where AEC-Q101 qualification, low leakage (<1 μA at VWM), and stable clamping under repetitive surge conditions are required.
Technical Context
The P4KE180CAHE3/54 operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity marking. Its glass-passivated junction enables fast response time (<1.0 ns) and low incremental surge resistance, critical for protecting sensitive downstream circuitry from inductive switching spikes and ESD events.
Thermally, it supports operation from –55 °C to +175 °C junction temperature, with 66 °C/W junction-to-lead thermal resistance and 100 °C/W junction-to-ambient (LLead = 10 mm). The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, distinguishing it from commercial-grade E3 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 171–189 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 246 V at IPPM = 1.6 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability per single 10/1000 μs transient; validates robustness against IEC 61000-4-5 surges. |
| ID (Reverse Leakage) | <1 μA at VWM - Minimal standby current; avoids power loss and false triggering in high-impedance circuits. |
| TJ max. | +175 °C - Enables use in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTOL, TC, HAST, and UHAST. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180CA | DO-214AA package; 180 V VBR; 200 W PPPM; lower clamping (292 V at 1.2 A); surface-mount only. | Preferred for space-constrained PCBs; unsuitable for through-hole legacy designs or high-power derating scenarios. | Select SMBJ180CA when board real estate is limited and peak surge energy does not exceed 200 W. |
| 1.5KE180CA | DO-201AD package; same VBR/VWM/VC specs; 1500 W PPPM; higher IFSM (125 A); larger footprint and thermal mass. | Better suited for infrequent but extreme surges (e.g., utility grid coupling); requires larger pad layout and thermal relief. | Choose 1.5KE180CA when system-level surge testing exceeds IEC 61000-4-5 Level 4 and PCB layout allows larger package. |
Compared with SMBJ180CA and 1.5KE180CA, the P4KE180CAHE3/54 delivers optimal balance of AEC-Q101 qualification, through-hole manufacturability, and 400 W surge handling-making it ideal for automotive and industrial through-hole assemblies where reliability and process compatibility are prioritized over miniaturization or ultra-high-power rating.

FAQ
What is the standoff voltage rating of the P4KE180CAHE3/54?
The P4KE180CAHE3/54 has a standoff voltage (VWM) of 154 V, meaning it remains non-conductive up to this DC or RMS voltage level. This value provides a safety margin below its 171–189 V breakdown range and ensures minimal leakage (<1 μA) during normal operation-critical for maintaining signal integrity in always-on automotive modules.
Is the P4KE180CAHE3/54 suitable for automotive applications?
Yes, the P4KE180CAHE3/54 is AEC-Q101 qualified (confirmed by the HE3 suffix), making it suitable for automotive applications including body control units, lighting drivers, and power distribution modules. Its –55 °C to +175 °C operating range, glass-passivated junction, and validated surge endurance meet stringent automotive reliability requirements.
How does the clamping voltage of P4KE180CAHE3/54 compare to its breakdown voltage?
The P4KE180CAHE3/54 clamps at 246 V when subjected to its rated 1.6 A peak pulse current (IPPM), which is approximately 37 % above its minimum breakdown voltage of 171 V. This controlled voltage overshoot ensures protected ICs experience stress within safe absolute maximum ratings while maintaining effective transient suppression.
What packaging format is used for the P4KE180CAHE3/54?
The P4KE180CAHE3/54 is supplied in 13-inch paper tape and reel format with a base quantity of 5500 units (package code 54). Its DO-41 (DO-204AL) through-hole package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Does the P4KE180CAHE3/54 have polarity markings?
No, the P4KE180CAHE3/54 is a bidirectional TVS diode and carries no polarity marking on its DO-41 package. Its symmetrical construction allows either lead to serve as anode or cathode depending on transient polarity-simplifying layout and eliminating orientation errors during manual or automated assembly.
