Product details
Overview
P6KE15A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 14.3 V minimum breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 21.2 V maximum clamping voltage at 28.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE15A-E3/54 datasheet, P6KE15A-E3/54 pinout, P6KE15A-E3/54 application, or P6KE15A-E3/54 equivalent, key selection criteria include its DO-15 package compatibility, unidirectional polarity with cathode band marking, 1.0 μA max reverse leakage at VWM, -55 °C to +175 °C operating junction temperature range, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 GΩ at 12.8 V), then rapidly avalanches below 14.3 V to clamp transients. Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance (Rdyn ≈ 0.32 Ω derived from ΔV/ΔI = (21.2 V − 14.3 V)/28.3 A).
The device sustains 600 W peak pulse power only at TA = 25 °C and derates linearly above 25 °C per Fig. 2; thermal resistance junction-to-lead is 20 °C/W, enabling direct PCB trace heat sinking. It is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 0.084 %/°C temperature coefficient of VBR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 14.3 V / 15.8 V at 1.0 mA test current - defines precise avalanche initiation threshold for reliable clamping onset |
| VWM | 12.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 21.2 V at 28.3 A (10/1000 μs) - ensures protected ICs see ≤21.2 V during worst-case surge |
| PPPM | 600 W - delivers robust transient energy absorption without degradation under defined waveform |
| IFSM | 100 A - withstands high-energy inductive turn-off surges common in relay/valve driver circuits |
| TJ range | -55 °C to +175 °C - supports operation in under-hood automotive and industrial ambient environments |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with 0.250" lead spacing and UL 94 V-0 molding |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; cathode identified by color band on body end. Leads conform to J-STD-002 and JESD 22-B102 solderability standards; RoHS compliant (E3 suffix), JESD 201 class 1A whisker tested.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during positive transients when cathode is biased higher |
| Cathode | Reverse-biased clamping terminal | Marked with color band; connected to protected line (e.g., 12 V rail or CAN_H); avalanches to shunt surge current to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, repeatable avalanche characteristics over 1000+ surge events without parameter drift |
| 600 W peak pulse power (10/1000 μs) | Handles typical ISO 7637-2 Pulse 1/2a/5a transients in 12 V automotive systems without failure |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive electronics per stress test requirements including HTGB, HTRB, and temperature cycling |
| Low clamping ratio (VC/VBR ≈ 1.49) | Minimizes overvoltage stress on downstream components such as microcontrollers and transceivers |
| 1.0 μA max reverse leakage at VWM | Prevents excessive standby current in battery-powered applications like telematics and ADAS sensors |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
|

IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between signal line and chassis ground, clamping transients within 1 ns. Use Value: Limits voltage seen by op-amp input stage to ≤21.2 V, preventing latch-up or oxide breakdown in precision ADC front-ends. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to 24 V DC field wiring with long cable runs. IC Role / Device Role / Timing Role: Primary overvoltage clamp on each discrete input channel, mounted adjacent to connector. Use Value: Absorbs 600 W surge energy from ESD or lightning-induced coupling without requiring series impedance or timing delay. |
| Consumer Power Adapter Input | Telecom Line Interface |
|
Use Scenario: Secondary-side DC bus protection in wall adapters subjected to conducted surges via AC mains or USB-C PD negotiation faults. IC Role / Device Role / Timing Role: Standoff-rated TVS across +5 V/3.3 V outputs to suppress cross-talk and regulator overshoot. Use Value: Maintains 12.8 V working margin while clamping to 21.2 V, ensuring LDOs and PMICs remain within absolute maximum ratings. |
Use Scenario: Overvoltage guard on Ethernet PHY interface lines (e.g., MDI pairs) in PoE-powered switches against induced surges. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on data lines referenced to local ground plane. Use Value: Adds <1 pF junction capacitance (per Fig. 4), preserving signal integrity up to 100 MHz without equalization penalty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Same VWM (12.8 V), same VC (21.2 V), but SMA package (surface-mount); 400 W PPPM | Requires PCB rework for SMT layout; unsuitable for through-hole prototyping or high-vibration mechanical mounting | Select when board space is constrained and automated assembly is used; verify thermal pad design for 20 °C/W RθJA |
| 1.5KE15A | Same DO-15 package and electrical specs, but 1500 W PPPM; larger die size increases capacitance and cost | Over-spec'd for most 12 V systems; may cause unnecessary BOM cost and longer lead times | Choose only if system-level testing confirms need for >600 W surge margin, e.g., heavy-duty truck alternator load dump |
Compared with SMAJ15A and 1.5KE15A, P6KE15A-E3/54 delivers optimal balance of proven 600 W surge capability, DO-15 mechanical robustness, and cost efficiency for volume automotive and industrial designs - without over-engineering or SMT conversion overhead.

FAQ
What is the exact breakdown voltage range for P6KE15A-E3/54?
The P6KE15A-E3/54 has a guaranteed breakdown voltage range of 14.3 V to 15.8 V at 1.0 mA test current (VBR), measured per ANSI/IEEE C62.35. This range ensures consistent clamping behavior across production lots and temperature extremes, directly supporting design margin calculations for protected ICs.
Is P6KE15A-E3/54 suitable for automotive applications?
Yes, P6KE15A-E3/54 is AEC-Q101 qualified when ordered with the HE3 suffix (e.g., P6KE15AHE3/54). The E3 suffix version is commercial grade but shares identical electrical and thermal specifications; for automotive use, specify the HE3 variant to ensure full qualification documentation and lot traceability.
What does the "-E3/54" suffix mean in P6KE15A-E3/54?
In P6KE15A-E3/54, "E3" denotes RoHS-compliant, matte tin-plated leads meeting JESD 201 class 1A whisker resistance, while "/54" specifies the preferred package code for 13-inch paper tape and reel packaging with 4000 units per reel - standard for automated SMT placement despite its axial DO-15 form factor.
How does P6KE15A-E3/54 compare to bidirectional variants like P6KE15CA?
P6KE15A-E3/54 is unidirectional with cathode marking and blocks reverse current until breakdown; P6KE15CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. Use P6KE15A-E3/54 for DC rails with defined ground reference; choose P6KE15CA only for AC-coupled or floating signal lines like telecom interfaces.
What is the maximum clamping voltage of P6KE15A-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE15A-E3/54 is 21.2 V at 28.3 A peak pulse current with a 10/1000 μs waveform. This value is guaranteed across temperature and lifetime, enabling accurate worst-case overvoltage analysis for downstream components such as 24 V-rated CAN transceivers or 3.3 V microcontroller I/O pins.
