Product details
Overview
P4KE16AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level overvoltage protection. It features a 16.8 V maximum breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 22.5 V clamping voltage at 17.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and signal lines of automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P4KE16AHE3/54 datasheet, P4KE16AHE3/54 pinout, P4KE16AHE3/54 application, or P4KE16AHE3/54 equivalent, key selection criteria include verified AEC-Q101 qualification, DO-41 mechanical compatibility, unidirectional polarity with cathode band marking, and clamping performance under 10/1000 μs transients per IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 13.6 V, it avalanches at VBR = 15.2–16.8 V (tested at 1.0 mA), limiting transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at VWM) across -55 °C to +175 °C junction temperature range.
Thermal design relies on RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm); power derating begins above 25 °C ambient, with full 1.5 W dissipation only at TL ≤ 75 °C. It supports 40 A non-repetitive forward surge (8.3 ms half-sine) but is rated for unidirectional operation only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V at 1.0 mA - defines reliable avalanche initiation threshold for overvoltage detection |
| VWM | 13.6 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 22.5 V at 17.8 A - clamping voltage during 10/1000 μs surge, limiting downstream IC stress |
| PPPM | 400 W - peak transient power handling capability per single 10/1000 μs pulse |
| IFSM | 40 A - max non-repetitive forward surge current (8.3 ms half-sine), critical for inductive turn-off events |
| TJ max | +175 °C - enables use in under-hood automotive and high-temperature industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|

IC Role / Device Role / Timing Role: Unidirectional TVS on each differential pair (TX+/TX−, RX+/RX−), grounded at chassis. Use Value: Withstands repeated 10/1000 μs surges up to 17.8 A while maintaining <1.0 μA leakage at 13.6 V standby. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | DO-214AA package; 16 V VBR min/max = 17.8–19.7 V; 600 W PPPM; higher VC = 26.0 V @ 24.7 A | Higher power handling but larger footprint; better suited for PCBs with >1.6 mm creepage clearance | Select SMBJ16A when 600 W surge margin is required and board space allows SMC/SMB package |
| 1.5KE16A | DO-201AD package; same VBR range (15.2–16.8 V); identical 400 W PPPM; VC = 22.5 V @ 17.8 A; no AEC-Q101 qualification | Commercial-grade only; not validated for automotive temperature cycling or humidity testing | Choose 1.5KE16A for cost-sensitive industrial or consumer designs where AEC-Q101 is not mandated |
Compared with SMBJ16A and 1.5KE16A, the P4KE16AHE3/54 delivers AEC-Q101 reliability in the compact DO-41 form factor, making it optimal for space-constrained automotive modules requiring proven field robustness without upgrading to SMC packages.

FAQ
What is the polarity configuration of the P4KE16AHE3/54?
The P4KE16AHE3/54 is a unidirectional TVS diode: its cathode is marked by a color band on the DO-41 package body. This configuration allows it to conduct only during reverse overvoltage events on the protected line, while blocking normal forward-biased operation. The P4KE16AHE3/54 does not function as a bidirectional device - for symmetrical clamping, a CA-suffixed variant like P4KE16CA would be required.
Does the P4KE16AHE3/54 meet automotive qualification standards?
Yes, the P4KE16AHE3/54 is explicitly AEC-Q101 qualified, as confirmed in Vishay document 88365 (Revision: 16-Sep-2021). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge (ESD), validating its suitability for automotive powertrain, chassis, and body electronics applications.
What is the clamping voltage of the P4KE16AHE3/54 under surge conditions?
The P4KE16AHE3/54 exhibits a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current (IPPM) of 17.8 A using the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper limit of voltage seen by downstream circuitry during transient suppression.
Can the P4KE16AHE3/54 be used in bidirectional signal line protection?
No - the P4KE16AHE3/54 is strictly unidirectional and must be oriented with cathode toward the protected line. For bidirectional protection (e.g., RS-485, CAN, or AC-coupled signals), a bidirectional variant such as P4KE16CA is required. Using P4KE16AHE3/54 on bidirectional lines risks forward conduction during normal signal swings and failure to clamp negative transients.
What is the thermal resistance profile of the P4KE16AHE3/54?
The P4KE16AHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient resistance (RθJA) of 100 °C/W (with 10 mm lead length). These values define its ability to dissipate 1.5 W continuously at TL ≤ 75 °C and inform layout decisions such as copper pour area and standoff height for thermal relief.
