Product details
Overview
P4KE10AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit protection against ESD and inductive switching transients. It features 10.5 V breakdown voltage (VBR), 14.5 V clamping voltage (VC) at 27.6 A peak pulse current, 400 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the P4KE10AHE3/54 datasheet, P4KE10AHE3/54 pinout, P4KE10AHE3/54 application, or P4KE10AHE3/54 equivalent, key selection criteria include standoff voltage (8.55 V), low clamping ratio (1.38×VBR), 175 °C max junction temperature, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-marked polarity (band denotes cathode). Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for protecting downstream ICs and MOSFETs from transient overvoltage events.
It is rated for 400 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle, with thermal resistance of 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient), supporting reliable operation in ambient temperatures from –55 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.5 V / 10.5 V at 1.0 mA test current - defines precise voltage threshold where clamping begins |
| VWM | 8.55 V - maximum continuous reverse working voltage before leakage exceeds 10 μA |
| VC @ IPPM | 14.5 V at 27.6 A - clamped voltage seen by protected circuit during worst-case transient |
| PPPM | 400 W - peak transient energy absorption capability with 10/1000 μs waveform |
| TJ max | +175 °C - enables use in under-hood automotive environments and high-power industrial enclosures |
| RθJL | 66 °C/W - supports thermal management when mounted on PCB with short lead lengths |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; cathode indicated by color band on body. Matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, rated for 275 °C dip soldering (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode | Clamping terminal | Marked end; connected to protected line - conducts during overvoltage to clamp to VC |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance (±5%) and long-term reliability under repeated surge stress |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards |
| 400 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without degradation when properly mounted |
| Low clamping ratio (VC/VBR = 1.38) | Minimizes voltage overshoot across protected ICs, reducing risk of latch-up or gate oxide damage |
| UL 94 V-0 molding compound | Provides flame-retardant housing essential for safety-critical industrial and automotive assemblies |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | DO-214AA package; 10.0 V VBR min, 17.0 V VC at 23.5 A; same 400 W rating but higher clamping voltage | Surface-mount alternative with lower profile; requires rework of PCB layout and thermal pad design | Preferred for space-constrained SMT designs where leaded DO-41 is not feasible |
| 1.5KE10A | Same DO-41 package; 10.0 V VBR min, 16.7 V VC at 23.9 A; 1500 W peak power rating | Higher power handling but larger junction capacitance and slower response due to larger die | Selected when system-level surge requirements exceed 400 W, e.g., telecom central office equipment |
Compared with SMBJ10A and 1.5KE10A, P4KE10AHE3/54 offers tighter VBR tolerance (±5% vs ±10%), lower clamping voltage (14.5 V vs 16.7–17.0 V), and AEC-Q101 qualification - making it optimal for cost-sensitive, high-reliability automotive and industrial board-level protection where axial lead mounting is acceptable.

FAQ
What is the breakdown voltage range of the P4KE10AHE3/54?
The P4KE10AHE3/54 has a guaranteed breakdown voltage (VBR) range of 9.5 V to 10.5 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight ±5% tolerance ensures predictable clamping onset and compatibility with 12 V nominal systems where overvoltage margin must be precisely controlled. The specification applies to each unit in production lot traceability.
Is the P4KE10AHE3/54 suitable for automotive applications?
Yes, the P4KE10AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junction, UL 94 V-0 epoxy, and matte tin-plated leads compliant with J-STD-002. The device operates from –55 °C to +175 °C and meets surge immunity requirements for engine control units, body electronics, and infotainment power rails as defined in ISO 7637-2.
What is the clamping voltage of the P4KE10AHE3/54 under peak pulse conditions?
The P4KE10AHE3/54 clamps to a maximum of 14.5 V at its rated peak pulse current of 27.6 A (10/1000 μs waveform). This value is measured per standard test conditions and represents the upper limit of voltage imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Does the P4KE10AHE3/54 have polarity marking, and how is it identified?
Yes, the P4KE10AHE3/54 is unidirectional and features a cathode band - a visible color ring near one end of the DO-41 package. This band identifies the cathode terminal, which must be connected to the line being protected (e.g., 12 V rail), while the anode connects to ground. No marking is present on bidirectional variants, but P4KE10AHE3/54 is strictly unidirectional per ordering code and datasheet designation.
What packaging format is used for the P4KE10AHE3/54, and what is the reel quantity?
The P4KE10AHE3/54 is supplied in 13-inch diameter paper tape and reel format with a base quantity of 5500 pieces per reel (ordering code suffix /54). The HE3 suffix confirms AEC-Q101 qualification and RoHS compliance, while the tape-and-reel configuration supports automated pick-and-place assembly in high-volume manufacturing environments.
