Product details
Overview
P4KE16A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed to clamp transient overvoltages on power and signal lines. It features 15.2 V minimum breakdown voltage (VBR), 13.6 V maximum stand-off voltage (VWM), 22.5 V clamping voltage (VC) at 17.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used for protecting MOSFETs and ICs against inductive switching surges in industrial power supplies.
For engineers reviewing the P4KE16A-E3/54 datasheet, P4KE16A-E3/54 pinout, P4KE16A-E3/54 application, or P4KE16A-E3/54 equivalent, key selection criteria include unidirectional polarity, DO-41 mechanical compatibility, 1.0 mA test current for VBR, 1.0 μA max reverse leakage at VWM, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping performance across repetitive transients.
The device supports unidirectional operation only (cathode marked by band), with 175 °C maximum junction temperature and thermal resistance of 66 °C/W (junction-to-lead). It complies with JESD 22-B106 for solderability (275 °C, 10 s) and meets UL 94 V-0 flammability requirements via molded epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V at 1.0 mA - defines precise avalanche onset range for reliable overvoltage triggering |
| VWM | 13.6 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 22.5 V at 17.8 A - clamped voltage during 400 W transient, limiting downstream stress on protected ICs |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform, supporting IEC 61000-4-5 Level 3/4 surge immunity |
| IFSM | 40 A - non-repetitive forward surge capability (8.3 ms half-sine), enabling robustness against accidental polarity reversal |
| TJ max | +175 °C - high-temperature operation suitable for under-hood automotive and industrial environments |
| RθJL | 66 °C/W - enables thermal design margin estimation when mounted on PCB with defined lead length |

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, 600 W PPPM, 25.5 V VC @ 24.7 A, surface-mount | Higher power rating but larger footprint; requires rework of through-hole layout | Select SMBJ16A for space-constrained designs needing >400 W surge margin and SMT assembly. |
| 1.5KE16A | Same DO-41 package, 1500 W PPPM, 25.5 V VC @ 59 A, higher leakage (5.0 μA) | Greater surge capacity but looser VBR tolerance (±10%) and higher clamping voltage | Choose 1.5KE16A where extreme surge robustness outweighs precision clamping and low-leakage needs. |
Compared with SMBJ16A and 1.5KE16A, the P4KE16A-E3/54 offers optimal balance of DO-41 through-hole compatibility, tight 15.2–16.8 V VBR tolerance, and ultra-low 1.0 μA leakage - making it preferred for cost-sensitive, thermally constrained, and automotive-qualified designs requiring predictable clamping behavior.

FAQ
What is the breakdown voltage range of the P4KE16A-E3/54?
The P4KE16A-E3/54 has a guaranteed breakdown voltage (VBR) range of 15.2 V to 16.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight ±5% tolerance ensures consistent overvoltage triggering across production lots and temperature ranges, critical for protecting 12 V system components without premature conduction.
Is the P4KE16A-E3/54 suitable for automotive applications?
Yes - the P4KE16A-E3/54 is AEC-Q101 qualified (as confirmed by HE3 suffix variants and documentation note), making it suitable for automotive body electronics, infotainment power rails, and sensor interface protection. Its 175 °C max junction temperature and robust surge handling meet stringent automotive reliability requirements.
What does the "-E3/54" suffix indicate in P4KE16A-E3/54?
The "-E3" denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel packaging containing 5500 units. This ordering code ensures traceable, standardized logistics for automated assembly.
How does the clamping voltage of P4KE16A-E3/54 compare to its stand-off voltage?
The P4KE16A-E3/54 has a maximum stand-off voltage (VWM) of 13.6 V and a clamping voltage (VC) of 22.5 V at 17.8 A. This 8.9 V differential provides sufficient margin to avoid false triggering during normal operation while ensuring rapid, controlled clamping during transients - essential for safeguarding 15 V-tolerant interfaces.
Can P4KE16A-E3/54 be used in bidirectional configurations?
No - the P4KE16A-E3/54 is strictly unidirectional, as indicated by its "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies CA-suffixed variants (e.g., P4KE16CA); using P4KE16A-E3/54 in reverse-biased AC applications would result in forward conduction and failure.
