Product details
Overview
P6KA15AHE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 12.8 V stand-off voltage (VWM), 14.3–15.8 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), 28.3 A peak pulse current (IPPM), and clamps to ≤21.2 V at rated surge - deployed in automotive power supply inputs, industrial sensor interfaces, and MOSFET gate protection circuits.
For engineers reviewing the P6KA15AHE3/54 datasheet, P6KA15AHE3/54 pinout, P6KA15AHE3/54 application, or P6KA15AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C maximum junction temperature, DO-204AC (DO-15) package compatibility, and verified clamping performance under repetitive 10/1000 μs transients in high-reliability embedded systems.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable leakage and clamping behavior across temperature. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until breakdown threshold is exceeded.
Rated for 600 W peak pulse power (10/1000 μs), it delivers low incremental surge resistance and fast response time (<1 ns), ensuring effective suppression of ESD, load dump, and inductive switching transients without affecting normal circuit operation below VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.8 V - Maximum continuous reverse working voltage before significant leakage; sets safe operating margin above nominal 12 V rail. |
| VBR (min/max) | 14.3 V / 15.8 V at 1 mA - Confirmed breakdown range ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | ≤21.2 V at 28.3 A - Clamping voltage limits downstream device stress during full-rated surge. |
| PPPM | 600 W (10/1000 μs) - Sustains standardized lightning/surge waveforms per IEC 61000-4-5 Level 4. |
| TJ max. | +185 °C - Enables use in under-hood automotive and high-ambient industrial environments without derating. |
| IFSM | 75 A (8.3 ms half-sine) - Withstands motor startup surges and relay coil de-energization spikes. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, molded epoxy case meeting UL 94 V-0; matte tin-plated leads, solderable per J-STD-002; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional clamp configuration. |
| Cathode | Reverse-biased terminal | Connected to protected line (e.g., 12 V rail); conducts only when transient exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Passivated anisotropic rectifier structure | Reduces parameter drift over temperature and lifetime; maintains tight VBR tolerance (±5 %) across -65 °C to +185 °C. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving clamping fidelity for sensitive ICs. |
| 10 s solder dip rating (275 °C) | Supports standard wave and reflow assembly without junction degradation or delamination. |
| JESD 201 Class 2 whisker resistance | Ensures long-term reliability in high-vibration automotive modules where tin whisker growth could cause shorts. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 16750-2) and jump-start transients. IC Role / Device Role / Timing Role: Primary shunt TVS placed upstream of DC-DC converter input. Use Value: Clamps to ≤21.2 V during 600 W surges, preventing damage to downstream regulators rated for 24 V absolute max. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loop) from ESD and field wiring faults. IC Role / Device Role / Timing Role: Unidirectional clamp on sensor transmitter output, referenced to system ground. Use Value: Sub-1 ns response captures fast ESD events (IEC 61000-4-2 ±8 kV contact), limiting induced voltage to <22 V. |
| MOSFET Gate Overvoltage Suppression | Telecom DC Power Rail Clamp |
Use Scenario: Preventing gate oxide rupture in high-side N-channel MOSFET drivers exposed to inductive kickback. IC Role / Device Role / Timing Role: TVS connected between gate and source, absorbing negative-going transients. Use Value: Low VC ensures gate-source voltage stays within ±20 V rating of common logic-level MOSFETs. | Use Scenario: Hardening -48 V telecom power distribution boards against lightning-induced surges (ITU-T K.20/K.44). IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), handling residual energy. Use Value: 600 W rating sustains multiple 10/1000 μs surges without parametric shift, supporting >100 kA system-level testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/57T | Same DO-214AC (SMA) package; 15 V VWM, 24.4 V VC @ 24.4 A - higher clamping voltage, lower IPPM. | Less effective for 12 V systems requiring tight clamping; better suited for 24 V rails. | Select if board space allows SMA footprint and clamping margin permits higher VC. |
| 1.5KE15A | DO-201AD package; same 15 V rating but 1.5 kW PPPM; larger size, higher thermal mass. | Used where higher single-event energy absorption is required, not for repetitive surge duty. | Choose for infrequent high-energy events (e.g., utility grid coupling), not automotive cycling. |
Compared with SMAJ15A-E3/57T and 1.5KE15A, the P6KA15AHE3/54 offers optimal balance of compact DO-15 packaging, AEC-Q101 qualification, and low 21.2 V clamping - making it preferred for space-constrained, high-cycle automotive and industrial control designs.

FAQ
What is the maximum operating junction temperature of the P6KA15AHE3/54?
The P6KA15AHE3/54 has a maximum junction temperature (TJ) of +185 °C, validated per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive applications and high-ambient industrial settings without thermal derating up to that limit. The P6KA15AHE3/54 maintains specified VBR and leakage performance across its full -65 °C to +185 °C operating range.
Is the P6KA15AHE3/54 suitable for bidirectional transient suppression?
No, the P6KA15AHE3/54 is a unidirectional TVS diode and is not rated for bidirectional operation. Its design supports clamping only in reverse bias above VBR; forward conduction follows standard silicon diode characteristics. For AC or bipolar signal line protection, a dedicated bidirectional part such as P6SMB15CAHE3/A must be used instead of the P6KA15AHE3/54.
What does the "HE3/54" suffix indicate in P6KA15AHE3/54?
The "HE3/54" suffix denotes RoHS-compliant construction (HE3), JESD 201 Class 2 whisker resistance, and packaging in 13-inch paper tape and reel with 4000 units per reel (54 = package code per Vishay ordering nomenclature). This confirms the P6KA15AHE3/54 meets automotive-grade plating and packaging requirements, distinct from non-HE3 variants.
How does the clamping voltage of P6KA15AHE3/54 compare to its breakdown voltage?
The P6KA15AHE3/54 has a breakdown voltage (VBR) range of 14.3 V to 15.8 V at 1 mA, while its maximum clamping voltage (VC) is 21.2 V at 28.3 A peak pulse current. This ~34 % overvoltage margin reflects the device's dynamic impedance under surge conditions and ensures protected circuits remain within safe voltage limits during standardized 10/1000 μs transients. The P6KA15AHE3/54 achieves this with low incremental resistance.
Can the P6KA15AHE3/54 replace older P6KE15A parts in existing designs?
The P6KA15AHE3/54 is not a direct drop-in replacement for P6KE15A due to differences in package (DO-204AC vs. DO-15 identical footprint but different lead form), thermal profile, and AEC-Q101 qualification status. While both share 15 V rating, the P6KA15AHE3/54 offers higher TJ (185 °C vs. 175 °C) and tighter VBR tolerance. Layout reuse is possible, but validation of surge performance and thermal margin under actual conditions is required before substituting P6KA15AHE3/54.
