Product details
Overview
P6KE150-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 150 V breakdown voltage (VBR min/max: 143–158 V), 128 V standoff voltage (VWM), 207 V clamping voltage (VC) at 2.9 A peak pulse current, 600 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the P6KE150-E3/54 datasheet, P6KE150-E3/54 pinout, P6KE150-E3/54 application, or P6KE150-E3/54 equivalent, this page delivers verified electrical parameters, DO-15 package mechanical data, clamping behavior under surge conditions, thermal resistance values, and validated alternative parts for circuit-level ESD and lightning transient protection design.
Technical Context
The P6KE150-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transients and low incremental surge resistance. Its unidirectional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 50 A only - consistent with VWM ≥ 10 V devices per specification note (3).
It complies with AEC-Q101 for automotive-grade reliability and is rated for 600 W peak pulse power (10/1000 µs waveform, 0.01% duty cycle), with thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient). The device fails short-circuit under severe overload, enabling fuse or breaker coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V - defines minimum and maximum voltage at which avalanche conduction begins reliably at 1 mA test current |
| VWM | 128 V - maximum continuous reverse working voltage before leakage exceeds 1 µA; sets upper limit for safe DC bias operation |
| VC @ IPPM | 207 V at 2.9 A - clamped voltage during 10/1000 µs surge; determines worst-case overvoltage seen by protected IC |
| PPPM | 600 W - peak transient power handling capacity; defines surge energy absorption capability without failure |
| IPPM | 2.9 A - maximum non-repetitive peak pulse current supported under standard 10/1000 µs waveform |
| TJ max. | +175 °C - maximum junction temperature rating; enables use in under-hood automotive and high-ambient industrial environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead; critical for estimating temperature rise during repetitive surges |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during positive transients when cathode is biased higher |
| Cathode | Avalanche conduction terminal | Marked with color band; connected to protected line (e.g., 12 V rail); clamps reverse transients by avalanching above VBR |
Key Features
| Feature | Design Value |
|---|---|

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 | Same VWM (128 V) and VC (207 V), but SMC package (higher IPPM = 3.2 A), 600 W rating, surface-mount | Requires PCB rework for SMT layout; better suited for high-density boards where through-hole DO-15 is impractical | Select SMBJ150A when space constraints prohibit axial-leaded components and thermal management supports SMT mounting |
| 1.5KE150A | Same VBR, VWM, VC, and DO-201 package; 1500 W rating (vs. 600 W), higher IPPM = 7.3 A, larger case | Higher surge margin for infrequent but extreme events (e.g., direct lightning coupling); requires larger board area and lead spacing | Choose 1.5KE150A where legacy designs demand higher pulse power headroom and mechanical envelope allows DO-201 size |
Compared with SMBJ150A and 1.5KE150A, P6KE150-E3/54 offers optimal balance of cost, proven reliability in through-hole automotive harness interfaces, and sufficient 600 W surge rating for most ISO 7637-2 and IEC 61000-4-5 Level 3 applications without over-engineering board space or BOM cost.

FAQ
What is the clamping voltage of P6KE150-E3/54 and how is it measured?
The clamping voltage of P6KE150-E3/54 is 207 V, measured at 2.9 A peak pulse current using the standardized 10/1000 µs double-exponential waveform per IEC 61000-4-5. This value represents the maximum voltage the device allows across its terminals during a defined surge event, directly protecting downstream components from overvoltage. The P6KE150-E3/54 achieves this clamping performance while maintaining a 128 V working voltage and 143–158 V breakdown range.
Is P6KE150-E3/54 suitable for automotive applications?
Yes, P6KE150-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and infotainment power supplies. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction, and 600 W surge capability meet ISO 7637-2 Pulse 1, 2a, and 5a requirements. The P6KE150-E3/54 E3 suffix denotes RoHS-compliant commercial grade, and HE3 variants are available for full AEC-Q101 traceability.
What does the "-E3/54" suffix mean in P6KE150-E3/54?
The "-E3/54" suffix indicates RoHS-compliant commercial-grade packaging: "E3" specifies matte tin-plated leads meeting JESD 201 Class 1A whisker resistance and J-STD-002 solderability, while "/54" denotes the preferred package code for 13-inch paper tape and reel delivery with 4000 units per reel. This configuration ensures compatibility with automated through-hole insertion equipment and satisfies environmental compliance requirements for global manufacturing.
How does P6KE150-E3/54 differ from bi-directional TVS diodes like P6KE150CA?
P6KE150-E3/54 is unidirectional and features a cathode band marking; it conducts only in reverse bias above VBR and blocks forward current up to 3.5 V at 50 A. In contrast, P6KE150CA is bi-directional with no polarity marking and clamps transients of either polarity symmetrically. The P6KE150-E3/54 is used where DC bias exists (e.g., +12 V rail to GND), while P6KE150CA suits AC-coupled or floating signal lines needing dual-polarity protection.
What is the thermal resistance of P6KE150-E3/54 and why does it matter?
P6KE150-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. These values determine how effectively heat from surge dissipation transfers out of the silicon die - critical for repetitive surge scenarios or elevated ambient temperatures. For example, under 2.9 A pulses at 0.01% duty cycle, RθJL helps estimate localized heating at the lead bond, ensuring long-term reliability in automotive under-hood deployments of the P6KE150-E3/54.
