Product details
Overview
P4KE180HE3/54 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 171 V to 189 V breakdown voltage (VBR), 154 V maximum working peak reverse voltage (VWM), 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 and industrial I/O interfaces.
For engineers reviewing the P4KE180HE3/54 datasheet, P4KE180HE3/54 pinout, P4KE180HE3/54 application, or P4KE180HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, glass-passivated junction, low incremental surge resistance, and verified clamping performance under repetitive transients induced by inductive load switching.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert transient energy away from downstream circuitry. Its 10/1000 μs waveform rating reflects standardized surge immunity testing per REA definitions, and thermal resistance (RθJL = 66 °C/W) enables reliable operation up to 175 °C junction temperature.
The device exhibits 0.108 %/°C temperature coefficient of VBR, ensuring predictable voltage threshold drift across operating range. With 1.0 mA test current (IT) and ≤1.0 μA reverse leakage at VWM, it maintains low standby power loss while delivering fast response time and excellent clamping ratio (VC/VBR ≈ 1.30).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V at 1.0 mA - defines precise avalanche onset window for repeatable clamping behavior |
| VWM | 154 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR |
| VC at IPPM | 246 V at 1.6 A - clamped voltage during 10/1000 μs surge; determines protected circuit's maximum stress level |
| PPPM | 400 W - peak transient power handling capacity; validates protection against common lightning/ESD surges |
| IFSM | 40 A - 8.3 ms half-sine surge current rating; supports robustness against inductive kickback in relay/motor circuits |
| TJ max | +175 °C - extended junction temperature rating enables use in under-hood automotive and high-ambient industrial environments |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A | DO-214AA package; 170 V VBR min; 274 V VC at 1.45 A; 600 W PPPM | Higher power rating but larger footprint; requires PCB layout change | Select SMBJ170A when higher surge margin is needed and board space allows SMC/SMB package |
| 1.5KE180A | DO-201AD package; same VBR/VC specs; 1.5 kW PPPM; higher IPPM (2.2 A) | Higher peak power capability; not AEC-Q101 qualified | Choose 1.5KE180A for non-automotive industrial applications requiring greater single-event energy absorption |
Compared with P4KE180HE3/54, SMBJ170A offers higher surge power in a surface-mount package but lacks AEC-Q101 validation, while 1.5KE180A delivers 3.75× higher peak power in through-hole DO-201AD but omits automotive qualification - making P4KE180HE3/54 the optimal choice where space-constrained AEC-Q101 compliance is mandatory.

FAQ
What is the breakdown voltage tolerance for P4KE180HE3/54?
The P4KE180HE3/54 has a specified breakdown voltage range of 171 V to 189 V at 1.0 mA test current (IT), representing ±5.6% tolerance around the nominal 180 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports precise system-level surge margin design in the P4KE180HE3/54.
Is P4KE180HE3/54 suitable for bidirectional transient protection?
No, P4KE180HE3/54 is a unidirectional TVS diode - its cathode band indicates polarity, and it conducts only in reverse avalanche mode. For bidirectional protection, Vishay offers the P4KE180CA variant. Using P4KE180HE3/54 in bidirectional configurations risks forward conduction failure; always verify polarity alignment in the P4KE180HE3/54 layout.
Does P4KE180HE3/54 meet automotive reliability standards?
Yes, the HE3 suffix confirms AEC-Q101 qualification for P4KE180HE3/54, covering stress tests including high-temperature reverse bias (HTRB), temperature cycling (TC), and unbiased highly accelerated stress testing (UHAST). This makes P4KE180HE3/54 appropriate for under-hood and cabin electronics where automotive-grade reliability is mandated.
What is the maximum clamping voltage of P4KE180HE3/54 under surge conditions?
The maximum clamping voltage (VC) of P4KE180HE3/54 is 246 V at 1.6 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed per datasheet Table on page 2 and defines the upper voltage limit imposed on protected circuitry during standardized surge events - a critical parameter in P4KE180HE3/54 system-level surge design.
Can P4KE180HE3/54 be used in surface-mount designs?
No, P4KE180HE3/54 uses the axial DO-41 (DO-204AL) through-hole package and is not compatible with SMT assembly. For surface-mount equivalents, consider SMBJ170A (DO-214AA) or SMCJ170A (DO-214AB); however, neither carries the AEC-Q101 qualification of P4KE180HE3/54, so redesign and requalification would be required.
