Product details
Overview
P4KE150-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 128 V standoff voltage (VWM), 143–158 V breakdown voltage (VBR) at 1 mA test current, 207 A peak pulse current (IPPM), and clamps to ≤207 V at that current under 10/1000 μs waveform.
For engineers reviewing the P4KE150-E3/73 datasheet, P4KE150-E3/73 pinout, P4KE150-E3/73 application, or P4KE150-E3/73 equivalent, key selection criteria include its 400 W peak pulse power rating, AEC-Q101 qualification for automotive use, glass-passivated junction for reliability, and DO-41 leaded package compatibility with through-hole PCB assembly.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, entering avalanche conduction when transient voltage exceeds its breakdown threshold. Its unidirectional polarity-marked with a cathode band-enables DC-biased line protection without reverse conduction during normal operation.
The device delivers 400 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, with thermal resistance of 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient). It supports operating junction temperatures from –55 °C to +175 °C and meets JESD 22-B106 solderability standards (275 °C, 10 s).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Surface-mount SMB package (vs. axial DO-41); same VWM (128 V), slightly lower VC (209 V @ 202 A) | Requires PCB re-layout for SMT assembly; better high-frequency response due to lower parasitic inductance | Select when board space is constrained and automated SMT placement is preferred over through-hole assembly |
| 1.5KE150A | Same DO-41 package but higher PPPM (1500 W); identical VWM/VBR/VC specs; larger die size increases thermal mass | Higher surge margin for infrequent extreme events (e.g., direct lightning coupling); not AEC-Q101 qualified | Select when legacy 1.5 kW surge immunity is mandated and automotive qualification is not required |
Compared with SMBJ150A and 1.5KE150A, the P4KE150-E3/73 offers AEC-Q101 qualification in a cost-effective DO-41 through-hole package, balancing automotive reliability, proven surge performance, and ease of manual or wave-solder assembly without requiring layout changes.

FAQ
What is the maximum clamping voltage of the P4KE150-E3/73 under surge conditions?
The P4KE150-E3/73 has a maximum clamping voltage (VC) of 207 V when subjected to its rated peak pulse current (IPPM) of 207 A under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the highest voltage the protected circuit will experience during full-rated surge conduction. The clamping performance is guaranteed across the full operating temperature range and remains stable due to the glass-passivated junction structure of the P4KE150-E3/73.
Is the P4KE150-E3/73 suitable for automotive applications?
Yes, the P4KE150-E3/73 is AEC-Q101 qualified, confirming its suitability for automotive applications such as engine control units, body electronics, and lighting modules. Its operating junction temperature range of –55 °C to +175 °C, robust surge handling (400 W, 10/1000 μs), and DO-41 package with matte tin-plated leads meet automotive reliability and solderability requirements. The P4KE150-E3/73 is explicitly listed in Vishay's AEC-Q101 qualified product documentation.
What does the "E3/73" suffix indicate in P4KE150-E3/73?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/73" specifies the packaging option: 73 = 1.5 kΩ tape-and-reel quantity (standard for DO-41 parts at Vishay). This distinguishes it from other variants like "/54" (5.5 kΩ reels) or "HE3" (AEC-Q101 qualified version). The P4KE150-E3/73 uses the same die and electrical specifications as other P4KE150A variants but is configured for commercial-volume automated assembly.
How does the P4KE150-E3/73 differ from bidirectional TVS diodes like P4KE150CA?
The P4KE150-E3/73 is unidirectional and features a cathode band for polarity-sensitive placement, allowing it to block reverse voltage up to 128 V while clamping positive transients. In contrast, P4KE150CA is bidirectional with symmetrical clamping in both directions and no polarity marking. The unidirectional P4KE150-E3/73 provides lower leakage (<1.0 μA) and avoids unnecessary conduction on negative half-cycles-making it ideal for DC-biased lines where reverse conduction must be avoided.
What is the thermal resistance of the P4KE150-E3/73, and how does it affect PCB layout?
The P4KE150-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient resistance (RθJA) of 100 °C/W with 10 mm lead length. For reliable operation under repetitive surges, PCB layout should provide adequate copper area around the leads-especially the cathode-to act as a heat sink. Minimizing lead length and using thermal relief pads improves heat transfer; this thermal profile enables the P4KE150-E3/73 to sustain its 400 W rating in typical through-hole mounting configurations.
