Product details
Overview
P6KE15HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 15 V breakdown voltage (VBR = 14.3–15.8 V at 1 mA), 12.8 V stand-off voltage (VWM), clamps to ≤21.2 V at 28.3 A peak pulse current (10/1000 µs), and delivers 600 W peak pulse power. It is AEC-Q101 qualified and used in automotive sensor interface protection.
For engineers reviewing the P6KE15HE3/54 datasheet, P6KE15HE3/54 pinout, P6KE15HE3/54 application, or P6KE15HE3/54 equivalent, key selection criteria include its 12.8 V working voltage, 21.2 V clamping performance at rated surge, DO-204AC (DO-15) package compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6KE15HE3/54 operates as a uni-directional avalanche diode with glass-passivated junction, optimized for fast transient suppression on positive-rail circuits. Its 20 °C/W junction-to-lead thermal resistance and 175 °C maximum junction temperature support sustained operation under repetitive surge conditions in constrained thermal environments.
It exhibits low incremental surge resistance and sub-nanosecond response time, enabling effective clamping of ESD, load dump, and inductive switching transients. The device complies with UL 497B recognition (QVGQ2) and meets JESD 201 Class 2 whisker resistance due to its HE3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 12.8 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | ≤21.2 V at 28.3 A (10/1000 µs) - clamping voltage limiting downstream component stress during surge |
| PPPM | 600 W - peak transient power handling capability without failure under standardized surge waveform |
| IFSM | 100 A (8.3 ms half-sine) - surge current rating for non-repetitive fault events like load dump |
| TJ max. | +175 °C - enables use in under-hood automotive environments and high-ambient industrial settings |
| RθJL | 20 °C/W - low thermal resistance supports PCB-level heat dissipation without heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Same VWM (12.8 V) and VC (21.2 V), but lower PPPM (400 W) and DO-214AC (SMA) surface-mount package | Requires PCB re-layout; suitable only where space-constrained SMT assembly is preferred over through-hole | Select SMAJ15A only when board real estate is limited and 400 W surge margin is sufficient for target threat model |
| 1.5KE15A | Identical electrical specs (VBR, VWM, VC, PPPM) and DO-204AC package, but commercial-grade (E3), not AEC-Q101 qualified | Lacks automotive qualification; acceptable for industrial/commercial systems without automotive lifecycle or reliability requirements | Choose 1.5KE15A for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with SMAJ15A and 1.5KE15A, the P6KE15HE3/54 uniquely combines AEC-Q101 qualification, DO-204AC through-hole mechanical robustness, and full 600 W surge capability-making it the only option qualified for under-hood automotive deployment without layout change or derating.

FAQ
What is the clamping voltage of the P6KE15HE3/54 under maximum surge conditions?
The P6KE15HE3/54 clamps to a maximum of 21.2 V when subjected to its rated 28.3 A peak pulse current (10/1000 µs waveform). This value is measured at the device terminals under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping performance is guaranteed across the full operating temperature range and forms the basis for downstream IC voltage tolerance analysis in designs using the P6KE15HE3/54.
Is the P6KE15HE3/54 suitable for automotive applications?
Yes, the P6KE15HE3/54 is AEC-Q101 qualified and specifically intended for automotive use. Its HE3 suffix denotes compliance with JESD 201 Class 2 whisker resistance and full qualification per AEC-Q101 stress tests-including temperature cycling, humidity bias HAST, and accelerated life testing. It is deployed in engine control units, body control modules, and ADAS sensor interfaces where reliability under harsh thermal and electrical conditions is mandatory. The P6KE15HE3/54 meets these requirements without derating up to +125 °C ambient.
What does the "HE3/54" suffix mean in P6KE15HE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "54" refers to the preferred package code for 13-inch paper tape and reel packaging containing 4000 units. This ordering format ensures traceable, automotive-grade material flow and automated placement compatibility. The P6KE15HE3/54 is distinct from commercial-grade variants (e.g., P6KE15A-E3/54) which lack AEC-Q101 validation and Class 2 whisker resistance.
How does the P6KE15HE3/54 compare to the 1.5KE15A in terms of reliability?
The P6KE15HE3/54 exceeds the 1.5KE15A in reliability due to its AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and UL 497B recognition-none of which apply to the 1.5KE15A. While both share identical electrical ratings (VBR, VC, PPPM), the P6KE15HE3/54 undergoes extended stress testing for automotive lifecycles, including 1000-hour high-temperature operating life and -55 °C to +175 °C thermal cycling. These validations make the P6KE15HE3/54 the only choice for safety-critical or mission-reliability applications where the 1.5KE15A is restricted to commercial-grade use.
Can the P6KE15HE3/54 be used in bi-directional configurations?
No, the P6KE15HE3/54 is a uni-directional TVS diode and must not be used in bi-directional applications. Its cathode-band marking and asymmetric IV characteristics are designed for single-polarity clamping-typically protecting positive rails referenced to ground. For bi-directional protection (e.g., AC lines or differential data buses), Vishay specifies CA-suffix parts such as P6KE15CA. Using the P6KE15HE3/54 in reverse-biased AC scenarios risks premature failure due to uncontrolled reverse conduction beyond its specified VWM and leakage limits.
