Product details
Overview
P6KE16AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of sensitive electronics. It features a 16.8 V maximum breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current, and 600 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 P6KE16AHE3/54 datasheet, P6KE16AHE3/54 pinout, P6KE16AHE3/54 application, or P6KE16AHE3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, DO-15 mechanical compatibility, thermal resistance (RθJL = 20 °C/W), and clamping performance under repetitive 0.01% duty cycle surges.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (13.6 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for suppressing ESD and inductive switching spikes.
Thermally, it supports continuous operation up to TJ = 175 °C and delivers 5.0 W power dissipation on infinite heatsink at TL = 75 °C. The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits low incremental surge resistance - enabling robust protection without significant voltage overshoot during high-current transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (max) | 16.8 V - guaranteed avalanche onset voltage at 1.0 mA test current; defines upper threshold for reliable clamping activation |
| VWM | 13.6 V - maximum continuous reverse operating voltage; must exceed system's normal signal or supply rail |
| VC @ IPPM | 22.5 V at 26.7 A - clamped voltage during 10/1000 µs surge; determines worst-case stress on protected IC inputs |
| PPPM | 600 W - peak pulse power handling capability; enables suppression of high-energy transients like ISO 7637-2 Pulse 1/2a/5a |
| IFSM | 100 A - surge current rating for 8.3 ms half-sine; validates robustness against motor-switching or relay-bounce events |
| TJ max. | 175 °C - maximum junction temperature; supports under-hood automotive use and high-ambient industrial environments |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; informs PCB copper pour requirements for sustained power dissipation |

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; 16.7 V VBR min, 25.8 V VC @ 23.3 A; lower RθJA (50 °C/W vs. 75 °C/W) | Suitable for surface-mount layouts; higher clamping voltage reduces margin for 3.3 V logic protection | Select SMBJ16A when board space constraints require SMD mounting and thermal management permits higher VC |
| 1.5KE16A | Same DO-15 package; identical VBR/VWM/VC specs but commercial-grade (non-AEC-Q101); 1.5 kW PPPM | Applicable in non-automotive industrial settings where qualification is not mandated | Choose 1.5KE16A for cost-sensitive consumer or telecom designs requiring higher single-pulse energy handling |
Compared with SMBJ16A and 1.5KE16A, P6KE16AHE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole reliability, and optimized clamping ratio (22.5 V) - making it the preferred choice for automotive Tier-1 sensor modules and industrial control systems requiring long-term field stability.

FAQ
What is the breakdown voltage tolerance for P6KE16AHE3/54?
The P6KE16AHE3/54 has a specified breakdown voltage range of 15.2 V (min) to 16.8 V (max) at 1.0 mA test current, corresponding to a ±5% tolerance around the nominal 16 V rating. This tight VBR distribution ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in safety-critical circuits such as automotive engine control units.
Is P6KE16AHE3/54 suitable for bidirectional transient protection?
No, P6KE16AHE3/54 is a unidirectional TVS diode - its cathode band indicates polarity, and it conducts only during positive transients relative to the anode. For bidirectional protection, Vishay offers the P6KE16CA variant. Using P6KE16AHE3/54 in bidirectional applications risks failure during negative excursions, as it lacks symmetrical clamping capability.
What does the HE3/54 suffix indicate in P6KE16AHE3/54?
The HE3 suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; the /54 indicates packaging in 13-inch paper tape and reel with 4000 units per reel. This distinguishes P6KE16AHE3/54 from commercial-grade P6KE16A-E3/54 (no AEC-Q101) and confirms suitability for automotive production environments.
How does P6KE16AHE3/54 perform under repeated surge conditions?
P6KE16AHE3/54 is rated for repetitive 10/1000 µs surges at 0.01% duty cycle, meaning it can sustain up to one pulse per second without thermal runaway. Its RθJL of 20 °C/W and TJ max. of 175 °C allow reliable operation in cyclic industrial environments - verified per Fig. 2 derating curves in Vishay document 88369 - provided lead temperature remains ≤75 °C during sustained pulsing.
Can P6KE16AHE3/54 replace P6KE15A in existing designs?
Yes, P6KE16AHE3/54 can substitute for P6KE15A with minor design review: VWM increases from 12.8 V to 13.6 V (+6.3%), VC rises from 21.2 V to 22.5 V (+6.1%), and IPPM decreases from 28.3 A to 26.7 A (−5.7%). These shifts maintain functional compatibility in most 12 V systems but require verification that the higher clamping voltage remains within protected IC's absolute maximum ratings.
