Product details
Overview
P4KE15AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level ESD and surge protection. It features 15 V breakdown voltage (VBR min/max: 14.3–15.8 V), 12.8 V stand-off voltage (VWM), 1.0 mA test current, 1.0 μA max reverse leakage at VWM, and clamps transients to ≤21.2 V at 18.9 A peak pulse current - deployed on power rails and I/O lines of automotive sensor modules.
For engineers reviewing the P4KE15AHE3/54 datasheet, P4KE15AHE3/54 pinout, P4KE15AHE3/54 application, or P4KE15AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 400 W 10/1000 μs peak pulse power rating, DO-41 mechanical compatibility, and verified clamping performance under repetitive surge stress in automotive-grade designs.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 14.3–15.8 V breakdown range. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting MOSFET gates and microcontroller I/O pins against inductive switching spikes.
Thermal design relies on RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm). The HE3 suffix confirms AEC-Q101 qualification, matte tin-plated leads compliant with J-STD-002, and JESD 201 Class 2 whisker resistance - meeting automotive reliability requirements without derating at TJ ≤ 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V at 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping behavior |
| VWM | 12.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | ≤21.2 V at 18.9 A - clamping voltage during 10/1000 μs surge, limiting downstream voltage stress |
| PPPM | 400 W - peak pulse power handling capability under standardized transient waveform |
| IFSM | 40 A - non-repetitive forward surge current rating (8.3 ms half-sine), supporting inrush tolerance |
| TJ max. | +175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| Package | DO-41 (DO-204AL) - industry-standard axial leaded package with UL 94 V-0 molded epoxy body |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, molded epoxy body with glass-passivated chip junction. Cathode indicated by color band on one end; anode is unmarked lead. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102.

| Low incremental surge resistance | Minimizes VC overshoot during high di/dt events, improving protection margin for downstream ICs |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and automotive material compliance standards |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control modules against ISO 7637-2 Pulse 1 and Pulse 2a transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC converter input to clamp negative-going spikes. Use Value: Clamps to ≤21.2 V at 18.9 A, preventing damage to 36 V-rated input stages while maintaining AEC-Q101 qualification. |
Use Scenario: Safeguarding analog outputs of pressure sensors in factory automation PLCs exposed to relay coil flyback. IC Role / Device Role / Timing Role: TVS mounted directly at sensor connector to suppress 10/1000 μs surges induced by nearby contactor switching. Use Value: 12.8 V stand-off ensures no interference during normal 0–10 V output operation; 400 W rating absorbs repeated 500 V transients. |
| Consumer Power Adapter Input Stage | Telecom Line Card Surge Protection |
Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters after rectification. IC Role / Device Role / Timing Role: Unidirectional TVS across +5 V/9 V/15 V output rails to prevent latch-up in GaN FET drivers. Use Value: 15 V VBR aligns with common adapter output voltages; DO-41 footprint allows easy integration into existing layouts. |
Use Scenario: Front-end protection on Ethernet PHY power pins in telecom base station line cards subjected to lightning-induced surges. IC Role / Device Role / Timing Role: TVS placed between isolated DC-DC output and PHY VDDIO to limit transient coupling from chassis ground. Use Value: 175 °C max junction temperature supports operation in sealed, high-ambient enclosures; 1.0 μA leakage avoids bias current errors. |
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 | Surface-mount SMB package (vs. axial DO-41); same VBR range (14.3–15.8 V), identical 400 W rating | Requires PCB rework for SMT assembly; better high-frequency impedance but lower thermal mass than DO-41 | Select when automated assembly and board space constraints outweigh manual repairability needs |
| 1.5KE15A | Higher 1500 W peak pulse power rating; same DO-41 package and VBR spec; larger die size increases capacitance | Overqualified for 400 W use cases; higher cost and larger footprint without benefit for standard automotive transients | Choose only if system-level testing requires >400 W margin or legacy 1.5KE footprint reuse is mandatory |
Compared with SMBJ15A and 1.5KE15A, P4KE15AHE3/54 delivers optimal balance of AEC-Q101 compliance, proven DO-41 reliability in through-hole automotive harnesses, and precise 15 V clamping - making it preferred for cost-sensitive, serviceable, and thermally constrained designs where 400 W suffices.

FAQ
What is the exact breakdown voltage range for P4KE15AHE3/54?
The P4KE15AHE3/54 has a guaranteed breakdown voltage range of 14.3 V to 15.8 V measured at 1.0 mA test current (IT). This range is specified per Vishay document 88365 and defines the minimum and maximum voltage at which the device enters avalanche conduction - critical for ensuring consistent clamping behavior across production lots.
Is P4KE15AHE3/54 suitable for automotive applications?
Yes, P4KE15AHE3/54 is AEC-Q101 qualified (as confirmed by the HE3 suffix), features matte tin-plated leads compliant with J-STD-002, and operates up to +175 °C junction temperature - making it approved for under-hood and cabin-mounted automotive electronics including body control modules and sensor interfaces.
What does the "HE3" suffix mean in P4KE15AHE3/54?
The "HE3" suffix in P4KE15AHE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and matte tin plating meeting J-STD-002 solderability standards - distinguishing it from commercial-grade "E3" variants and confirming suitability for automotive production.
How does P4KE15AHE3/54 compare to P4KE15A-E3/54?
P4KE15AHE3/54 and P4KE15A-E3/54 share identical electrical specs (VBR, VWM, VC, PPPM) and DO-41 packaging, but only P4KE15AHE3/54 carries AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - essential for automotive use where P4KE15A-E3/54 is limited to commercial-grade applications.
What is the maximum clamping voltage of P4KE15AHE3/54 during a surge event?
The maximum clamping voltage (VC) of P4KE15AHE3/54 is 21.2 V at 18.9 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88365 and represents the upper limit of voltage seen by protected circuitry during worst-case transient conditions.
