Product details
Overview
P4KE150AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 150 V breakdown voltage (VBR min/max: 143–158 V), 128 V stand-off voltage (VWM), 207 A peak pulse current (IPPM), 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification - used to protect MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the P4KE150AHE3/54 datasheet, P4KE150AHE3/54 pinout, P4KE150AHE3/54 application, or P4KE150AHE3/54 equivalent, key selection criteria include clamping voltage (VC = 207 V at IPPM), thermal resistance (RθJL = 66 °C/W), RoHS-compliant matte tin leads, and JESD 201 Class 2 whisker resistance.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated junction and fast response time (<1 ns). Its 10/1000 µs waveform rating supports repetitive surge suppression at 0.01% duty cycle, and it exhibits low incremental surge resistance for stable clamping under high-current transients.
The device is rated for TJ = –55 °C to +175 °C operation, with 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C. Its forward voltage is 5.0 V at 25 A (per note 3), and it meets UL 94 V-0 flammability requirements via molded epoxy DO-41 packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V - defines minimum and maximum voltage at which device enters avalanche conduction during transient events |
| VWM | 128 V - maximum continuous reverse working voltage before leakage exceeds 1 µA; sets safe operating margin below clamping threshold |
| VC @ IPPM | 207 V - clamped voltage seen by protected circuit when subjected to full 207 A surge, critical for downstream component survivability |
| IPPM | 207 A - peak surge current capability with 10/1000 µs waveform; determines protection level against lightning or inductive switch-off spikes |
| PPPM | 400 W - peak pulse power handling capacity; validates suitability for automotive load-dump and ISO 7637-2 pulse 5a/b compliance |
| TJ max. | +175 °C - maximum junction temperature enabling reliable operation in under-hood automotive environments |
| RθJL | 66 °C/W - thermal resistance from junction to lead; informs PCB copper pour and heatsinking requirements for sustained surge duty |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; matte tin-plated terminals solderable per J-STD-002/JESD 22-B102; cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | DO-214AA package; 150 V VBR; 200 A IPPM; 400 W PPPM; surface-mount | Requires PCB rework for SMD layout; better thermal performance in high-density designs | Select SMBJ150A when board space is constrained and automated assembly is preferred over through-hole mounting. |
| 1.5KE150A | Same DO-41 package; identical VBR/VWM/VC; 1.5 kW PPPM; 3x higher peak power rating | Over-specified for most 400 W use cases; larger physical size and higher cost | Choose 1.5KE150A only where legacy 1.5 kW surge test profiles apply or where derating margin beyond 400 W is mandated. |
Compared with SMBJ150A, P4KE150AHE3/54 offers proven through-hole mechanical stability and AEC-Q101 qualification, while 1.5KE150A provides higher surge headroom at the expense of footprint and cost efficiency.

FAQ
What is the clamping voltage of P4KE150AHE3/54 at its rated peak pulse current?
The clamping voltage (VC) of P4KE150AHE3/54 is 207 V when subjected to its specified peak pulse current (IPPM) of 207 A under a 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88365 and defines the maximum voltage imposed on the protected circuit during worst-case surge conditions. The P4KE150AHE3/54 maintains this clamping performance across its qualified operating temperature range.
Is P4KE150AHE3/54 suitable for automotive applications?
Yes, P4KE150AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay's documentation. Its DO-41 package, 175 °C maximum junction temperature, and JESD 201 Class 2 whisker resistance make it appropriate for engine control units, body control modules, and sensor interface protection. The P4KE150AHE3/54 meets requirements for under-hood thermal cycling and long-term reliability in automotive power networks.
What does the "HE3/54" suffix indicate in P4KE150AHE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery with 5500 units per reel. This distinguishes P4KE150AHE3/54 from commercial-grade variants like P4KE150A-E3/54. The P4KE150AHE3/54 is traceable to Vishay's qualified automotive production line.
How does P4KE150AHE3/54 differ from bidirectional TVS diodes like P4KE150CA?
P4KE150AHE3/54 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P4KE150CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The P4KE150AHE3/54 has a forward voltage drop (~5.0 V at 25 A), while P4KE150CA does not conduct forward - making P4KE150AHE3/54 suitable for DC supply rail protection where polarity is fixed and known.
What is the thermal resistance from junction to lead for P4KE150AHE3/54?
The typical thermal resistance from junction to lead (RθJL) for P4KE150AHE3/54 is 66 °C/W, as specified in Vishay document 88365. This parameter governs heat transfer from the silicon die to the PCB copper via axial leads and directly impacts surge repetition rate capability. For sustained surge duty, the P4KE150AHE3/54 requires adequate PCB copper area and lead length optimization to maintain junction temperature within the –55 °C to +175 °C operating range.
