Product details
Overview
P6KE150CHE3/54 from Vishay General Semiconductor is a uni-directional 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 = 143 V, max = 158 V), 128 V stand-off voltage (VWM), 207 A peak pulse current (IPPM) under 10/1000 μs waveform, and clamps to ≤207 V at rated surge - used to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients in automotive ECUs and industrial PLC I/O modules.
For engineers reviewing the P6KE150CHE3/54 datasheet, P6KE150CHE3/54 pinout, P6KE150CHE3/54 application, or P6KE150CHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package with matte tin-plated leads, 600 W peak pulse power rating, and verified clamping performance at 25 °C ambient - critical for robust ESD and lightning surge protection in safety-critical embedded systems.
Technical Context
This TVS diode employs a glass passivated silicon junction optimized for fast response (<1 ns) and low dynamic impedance during transient events. Its unidirectional polarity uses a cathode band marking and operates with a maximum reverse leakage of 1.0 μA at 128 V, ensuring minimal standby power loss in always-on circuits.
The device delivers 600 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, derating linearly above 25 °C with RθJA = 75 °C/W and RθJL = 20 °C/W. It sustains 100 A non-repetitive forward surge current (IFSM) and exhibits a temperature coefficient of +0.108 %/°C on VBR, enabling stable clamping across automotive-grade temperature ranges (–55 °C to +175 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V at 1.0 mA test current - defines reliable conduction onset threshold for overvoltage triggering |
| VWM | 128 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| IPPM | 207 A at 10/1000 μs waveform - peak surge current it safely clamps without failure |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V/24 V battery-fed microcontroller power inputs in engine control units against load dump surges up to 120 V. IC Role / Device Role / Timing Role: Primary clamping device placed upstream of LDO regulators and MCU VDD pins. Use Value: Limits transient voltage to ≤207 V within nanoseconds, preventing latch-up or gate oxide damage in downstream ICs. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop transmitters) from ESD and cable discharge events in factory automation sensors. IC Role / Device Role / Timing Role: Bidirectional-capable protection element (though P6KE150CHE3/54 is uni-directional, used with series resistor for bidirectional effect) on signal path. Use Value: Clamps fast transients while maintaining <1.0 μA leakage at 128 V, preserving signal accuracy and offset stability. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Input Protection |
|

Use Scenario: Overvoltage protection on primary-side rectified DC bus in AC/DC adapters subjected to mains overvoltage and capacitor discharge events. IC Role / Device Role / Timing Role: Standoff-rated TVS placed across bulk capacitor to absorb energy from MOV failure or rectifier ringback. Use Value: 128 V VWM ensures no conduction during normal 110–240 VAC operation; 207 V clamping prevents capacitor overvoltage rupture. |
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 (Vishay) | Same VBR range (143–158 V), but SMB package (DO-214AA); 600 W rating, lower RθJA (50 °C/W) | Better thermal performance in space-constrained PCB layouts; requires footprint redesign | Select when board area is limited and higher power density is needed without changing circuit topology |
| 1.5KE150A (ON Semiconductor) | Identical DO-204AC package and electrical specs (VBR, VC, PPPM); not AEC-Q101 qualified | Suitable for commercial/industrial use only; lacks automotive reliability validation | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with SMBJ150A-E3/52 and 1.5KE150A, P6KE150CHE3/54 offers AEC-Q101 qualification in the legacy DO-15 through-hole package - making it ideal for legacy automotive harness assemblies and high-vibration mechanical mounting where lead strength and solder joint robustness are prioritized over miniaturization.

FAQ
What is the clamping voltage of P6KE150CHE3/54 at its rated peak pulse current?
The P6KE150CHE3/54 has a maximum clamping voltage (VC) of 207 V when subjected to its rated 207 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on the protected circuit during worst-case surge events. The P6KE150CHE3/54 maintains this clamping performance consistently due to its glass-passivated junction and low dynamic impedance.
Is P6KE150CHE3/54 suitable for automotive applications?
Yes, P6KE150CHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including matte tin-plated leads, JESD 201 Class 2 whisker resistance (HE3 suffix), and operation from –55 °C to +175 °C - meets stringent automotive reliability requirements. The P6KE150CHE3/54 is commonly deployed in engine control units, body control modules, and ADAS power supplies where load dump and jump-start transients must be suppressed.
What does the "HE3/54" suffix mean in P6KE150CHE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "54" denotes the preferred package code for 13-inch paper tape and reel packaging with a base quantity of 4000 units. The P6KE150CHE3/54 is supplied in this format to support automated SMT placement - though its DO-204AC (DO-15) package is through-hole, the tape-and-reel enables compatible pick-and-place handling in hybrid assembly lines.
How does P6KE150CHE3/54 differ from bi-directional P6KE150CA variants?
P6KE150CHE3/54 is a uni-directional TVS diode with cathode band marking and forward voltage drop (~5.0 V at 50 A), intended for DC rail protection where polarity is fixed. In contrast, P6KE150CA is bi-directional - symmetric in both directions, no polarity marking, and no forward conduction path - suited for AC lines or differential signal pairs. The P6KE150CHE3/54 cannot replace P6KE150CA in AC-coupled applications without circuit redesign.
What is the maximum reverse leakage current for P6KE150CHE3/54 at its stand-off voltage?
The maximum reverse leakage current (ID) for P6KE150CHE3/54 is 1.0 μA at its rated stand-off voltage (VWM) of 128 V and TA = 25 °C. This low leakage ensures minimal power loss in always-on systems and preserves signal integrity in high-impedance sensor interfaces. The P6KE150CHE3/54 maintains this specification across its full operating temperature range, supporting precision analog and low-power IoT applications.
