Product details
Overview
P6KE150HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 150 V breakdown voltage (VBR min/max = 143 V / 158 V), 128 V stand-off voltage (VWM), 207 V clamping voltage (VC) at 2.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the P6KE150HE3/54 datasheet, P6KE150HE3/54 pinout, P6KE150HE3/54 application, or P6KE150HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 0.108 %/°C VBR temperature coefficient, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability standards.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 128 V), then rapidly avalanches below 207 V to divert surge energy away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for suppressing ESD and inductive switching transients.
The device is rated for 100 A non-repetitive forward surge current (IFSM) and exhibits 20 °C/W typical junction-to-lead thermal resistance - enabling reliable operation without heatsinking in moderate-duty-cycle applications such as 12 V/24 V automotive control modules and PLC I/O protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V at 1.0 mA test current - defines precise avalanche initiation threshold for consistent clamping behavior |
| VWM | 128 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 207 V at 2.9 A peak pulse current - limits protected circuit voltage during 600 W transient events |
| PPPM | 600 W with 10/1000 µs waveform - sustains high-energy surges common in automotive load-dump scenarios |
| TJ max | 175 °C - supports operation in under-hood automotive environments and industrial enclosures |
| RθJL | 20 °C/W - enables effective heat transfer to PCB copper or lead frame without external heatsink |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |

Use Scenario: RS-485 transceiver ports in outdoor telecom cabinets subjected to induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: TVS placed differential-mode across A/B lines and common-mode to ground to suppress both modes simultaneously. Use Value: 128 V VWM permits full 12 V common-mode range while clamping differential surges to safe levels for 3.3 V transceivers. |
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-E3/52 | DO-214AA package; same VBR (143–158 V), but lower 600 W rating and higher VC (243 V @ 2.5 A) | Surface-mount alternative requiring PCB redesign; better suited for space-constrained consumer electronics | Select when board space is limited and reflow assembly is preferred over through-hole mounting |
| 1.5KE150A | Same DO-204AC package and electrical specs, but commercial-grade only (no AEC-Q101 qualification) | Lacks automotive qualification; suitable for industrial or telecom equipment not requiring automotive reliability | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with SMBJ150A-E3/52 and 1.5KE150A, P6KE150HE3/54 uniquely combines AEC-Q101 qualification, axial through-hole DO-15 packaging, and verified 207 V clamping performance - making it the preferred choice for automotive and harsh-environment industrial deployments requiring proven reliability and legacy-compatible assembly.

FAQ
What is the clamping voltage of P6KE150HE3/54 and how is it measured?
The clamping voltage (VC) of P6KE150HE3/54 is 207 V, measured at 2.9 A peak pulse current using a 10/1000 µs waveform per IEC 61000-4-5. This value represents the maximum voltage seen across the device during a standardized surge event - directly limiting stress on downstream components. The P6KE150HE3/54 achieves this clamping level while maintaining low incremental resistance, ensuring predictable protection behavior in real-world transients.
Is P6KE150HE3/54 suitable for automotive applications?
Yes, P6KE150HE3/54 is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body control modules, and infotainment power supplies. Its 175 °C maximum junction temperature, glass-passivated junction, and matte tin-plated leads (JESD 201 Class 2) meet automotive reliability requirements. The P6KE150HE3/54 has been validated for load-dump immunity and thermal cycling - confirming its suitability for under-hood and cabin-mounted systems.
What does the HE3/54 suffix mean in P6KE150HE3/54?
The HE3 suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; the /54 denotes 13-inch paper tape and reel packaging with 4000 units per reel. This distinguishes P6KE150HE3/54 from commercial-grade variants (e.g., P6KE150A-E3/54) and confirms its suitability for automotive production. The P6KE150HE3/54 meets all mechanical, thermal, and reliability requirements specified in the Vishay P6KE family datasheet (88369).
How does P6KE150HE3/54 compare to P6KE150A in terms of reliability?
P6KE150HE3/54 adds AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and enhanced process controls versus standard P6KE150A - resulting in superior long-term reliability in automotive and industrial environments. While both share identical electrical specs (VBR, VC, PPPM), the P6KE150HE3/54 undergoes additional stress testing including HTGB, H3TRB, and temperature cycling. For mission-critical applications, P6KE150HE3/54 provides documented reliability assurance that P6KE150A does not offer.
Can P6KE150HE3/54 be used in bi-directional configurations?
No, P6KE150HE3/54 is a uni-directional TVS diode - identified by the "A" suffix and cathode band marking. Bi-directional variants use the "CA" suffix (e.g., P6KE150CA). Using P6KE150HE3/54 in reverse-biased mode would result in uncontrolled conduction and potential failure. For AC or bidirectional signal line protection, select the appropriate CA-series part; the P6KE150HE3/54 must be installed with cathode toward the protected line and anode to reference ground.
