Product details
Overview
P6KE15AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 15 V breakdown voltage (VBR min/max = 14.3–15.8 V), 12.8 V stand-off voltage (VWM), 21.2 V clamping voltage at 28.3 A peak pulse current (VC), and 600 W peak pulse power capability with 10/1000 μs waveform.
For engineers reviewing the P6KE15AHE3/54 datasheet, P6KE15AHE3/54 pinout, P6KE15AHE3/54 application, or P6KE15AHE3/54 equivalent, key selection criteria include clamping performance under 28.3 A surge, unidirectional polarity for DC rail protection, AEC-Q101 qualification for automotive-grade reliability, and DO-15 mechanical compatibility with legacy through-hole layouts.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (<1 μA leakage at 12.8 V), but triggers into low-impedance conduction when transient voltage exceeds its 14.3–15.8 V breakdown range. Its glass-passivated junction ensures stable VBR tolerance and fast response time (<1 ns), critical for protecting MOSFET gates and IC inputs.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); derating begins above 25 °C ambient, with full power (5.0 W) only sustainable at TL ≤ 75 °C. The device fails short-circuit under severe overload, enabling fuse/breaker coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V - defines precise voltage threshold where clamping initiates; tight 10% tolerance enables accurate overvoltage margining |
| VWM | 12.8 V - maximum continuous working voltage; must exceed system DC rail (e.g., 12 V automotive) to avoid leakage-induced power loss |
| VC @ IPPM | 21.2 V @ 28.3 A - clamped voltage during 10/1000 μs surge; determines protected circuit's maximum transient exposure |
| PPPM | 600 W - peak pulse power handling; supports robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) |
| IPPM | 28.3 A - peak pulse current capacity; sets minimum series impedance required to limit surge energy into the device |
| TJ max | +175 °C - maximum junction temperature; enables operation in under-hood automotive environments with minimal thermal margin loss |
| AEC-Q101 | Qualified - validated for automotive applications including engine control units and body electronics per stress test requirements |
Pinout & Package

IC Role / Device Role / Timing Role: Primary-level clamping device on DC bias feed to PoE circuitry; coordinates with gas discharge tube (GDT) for staged protection. Use Value: Clamps fast-rising transients to 21.2 V before GDT fires, preventing latch-up in IEEE 802.3af/at compliant controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Same VBR (14.3–15.8 V) and VC (24.4 V @ 24.4 A), but SMC package (surface-mount) with higher IPPM (24.4 A vs. 28.3 A) and lower RθJA (50 °C/W) | Requires PCB redesign for SMD layout; better suited for space-constrained consumer electronics than through-hole automotive harnesses | Select SMBJ15A when board space is limited and reflow soldering is available; retain P6KE15AHE3/54 for legacy through-hole production or high-vibration mounting. |
| 1.5KE15A | Identical electrical specs (VBR, VC, PPPM) and DO-15 package, but commercial-grade (E3 suffix), not AEC-Q101 qualified | Lacks automotive qualification testing; unsuitable for safety-critical vehicle subsystems despite identical form/fit/function | Choose 1.5KE15A for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated. |
Compared with SMBJ15A and 1.5KE15A, P6KE15AHE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole robustness, and verified 28.3 A surge handling-making it the only option qualified for under-hood automotive deployment without layout change or reliability compromise.

FAQ
What is the clamping voltage of P6KE15AHE3/54 and how is it measured?
The clamping voltage of P6KE15AHE3/54 is 21.2 V, measured at 28.3 A peak pulse current using a 10/1000 μs waveform per IEC 61000-4-5. This value represents the maximum voltage imposed on the protected circuit during a standardized surge event and is guaranteed across the full operating temperature range. The P6KE15AHE3/54 achieves this clamping performance due to its low incremental surge resistance and glass-passivated junction structure.
Is P6KE15AHE3/54 suitable for automotive applications?
Yes, P6KE15AHE3/54 is AEC-Q101 qualified, meaning it has passed rigorous stress tests-including temperature cycling, humidity bias, and high-temperature reverse bias-for use in automotive electronic systems. Its DO-15 package provides mechanical robustness for under-hood environments, and its 175 °C maximum junction temperature supports operation in engine control units and body control modules where ambient temperatures exceed 125 °C.
What does the HE3/54 suffix indicate in P6KE15AHE3/54?
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 P6KE15AHE3/54 from commercial-grade variants like P6KE15AE3/54 (no AEC-Q101) and confirms compliance with automotive supply chain traceability and reliability requirements.
How does P6KE15AHE3/54 differ from bidirectional TVS diodes?
P6KE15AHE3/54 is unidirectional, featuring a cathode band and conducting only when anode-to-cathode voltage exceeds 14.3–15.8 V; it blocks reverse voltage up to 12.8 V. Bidirectional variants (e.g., P6KE15CA) conduct symmetrically in both directions and lack polarity marking. Use P6KE15AHE3/54 on DC rails where polarity is fixed; choose bidirectional types only for AC-coupled or floating signal lines.
What is the maximum leakage current of P6KE15AHE3/54 at its stand-off voltage?
The maximum reverse leakage current of P6KE15AHE3/54 is 1.0 μA at its 12.8 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage ensures negligible power loss in always-on automotive modules and prevents false triggering in high-impedance sensor circuits. Leakage remains below 5 μA across the full -55 °C to +125 °C operating range per datasheet characterization.
