Product details
Overview
P6KE150CHE3/73 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 143 V minimum breakdown voltage (VBR), 128 V maximum stand-off voltage (VWM), 207 A peak pulse current (IPPM) under 10/1000 μs waveform, 600 W peak pulse power (PPPM), and clamps to ≤207 V at rated surge current - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the P6KE150CHE3/73 datasheet, P6KE150CHE3/73 pinout, P6KE150CHE3/73 application, or P6KE150CHE3/73 equivalent, key selection criteria include verified clamping voltage at 207 A, AEC-Q101 qualification status, DO-204AC (DO-15) package thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B for telecom/sensor protection circuits.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VWM = 128 V, it avalanches into low-impedance conduction to divert transient energy away from downstream ICs. Its glass-passivated junction enables fast response (<1 ns) and stable breakdown characteristics across temperature.
Designed for single-pulse and low-duty-cycle repetitive transients (0.01 % max duty cycle), it sustains 600 W peak power only under standardized 10/1000 μs waveform testing. Thermal derating applies above TA = 25 °C per Fig. 2, with maximum junction temperature limited to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse operating voltage before avalanche onset; defines safe DC bias margin for protected line. |
| VBR (Breakdown Voltage) | 143–158 V at IT = 1 mA - Confirmed avalanche initiation range; ensures reliable triggering above system nominal voltage. |
| VC (Clamping Voltage) | ≤207 V at IPPM = 207 A - Measured maximum voltage seen by protected circuit during 10/1000 μs surge; critical for IC survival. |
| PPPM (Peak Pulse Power) | 600 W - Sustained under standardized 10/1000 μs waveform; defines transient energy handling capacity. |
| IPPM (Peak Pulse Current) | 207 A - Maximum non-repetitive surge current the device can safely clamp; determines protection level against lightning/ESD. |
| RθJL (Junction-to-Lead Thermal Resistance) | 20 °C/W - Enables direct PCB copper pour heat sinking; supports 5.0 W steady-state dissipation at TL = 75 °C. |
| Operating Temperature | −55 °C to +175 °C - Validated junction temperature range; supports under-hood automotive and industrial ambient conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | DO-214AA package; 130 V VWM, 144–159 V VBR, 192 V VC @ 171 A; lower PPPM = 600 W but smaller footprint. | Preferred for space-constrained PCBs; lacks AEC-Q101 qualification in standard grade; requires HE3 variant for automotive. | Select SMBJ130A when board area is limited and thermal mass is sufficient to manage RθJA = 40 °C/W. |
| 1.5KE150A | DO-201AD package; identical VWM/VBR/VC specs; same 600 W rating but higher RθJL = 25 °C/W; no AEC-Q101 option. | Used in legacy industrial designs; larger body increases mounting stability but reduces density; not qualified for automotive use. | Choose 1.5KE150A only for cost-sensitive commercial equipment where AEC-Q101 is unnecessary and lead length allows thermal relief. |
Compared with SMBJ130A and 1.5KE150A, P6KE150CHE3/73 uniquely combines AEC-Q101 qualification, DO-15 mechanical robustness, and 20 °C/W junction-to-lead thermal resistance - making it optimal for high-reliability automotive and industrial power rail protection where thermal management and qualification are mandatory.

FAQ
What is the clamping voltage of P6KE150CHE3/73 at its rated peak pulse current?
The P6KE150CHE3/73 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 per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE150CHE3/73 maintains this clamping performance across its full operating temperature range of −55 °C to +175 °C.
Is P6KE150CHE3/73 qualified for automotive applications?
Yes, P6KE150CHE3/73 is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its part number and documented in Vishay's official datasheet revision 18-Sep-12. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for under-hood and chassis-mounted automotive electronics. The P6KE150CHE3/73 meets all requirements for use in engine control units, body control modules, and ADAS power supplies.
What does the "HE3" suffix indicate in P6KE150CHE3/73?
The "HE3" suffix in P6KE150CHE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from the commercial-grade "E3" version (e.g., P6KE150AE3/73), which lacks automotive qualification. The HE3 marking confirms compliance with automotive reliability standards, UL 497B recognition, and enhanced plating integrity for long-term solder joint reliability in thermally demanding environments.
Can P6KE150CHE3/73 be used for bi-directional transient protection?
No, P6KE150CHE3/73 is a uni-directional TVS diode, intended for DC rail protection where polarity is fixed. For bi-directional applications - such as AC lines or differential signal pairs - Vishay specifies CA-suffix variants (e.g., P6KE150CA). Using P6KE150CHE3/73 in reverse-biased AC configurations risks forward conduction and failure; always match device polarity to circuit topology. The P6KE150CHE3/73 data sheet explicitly states polarity designation via cathode band and excludes bi-directional operation.
What is the thermal resistance from junction to lead for P6KE150CHE3/73?
The P6KE150CHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the Thermal Characteristics table of its datasheet. This low value enables effective heat transfer from the silicon die to PCB copper pours or heatsinking leads, supporting its 5.0 W steady-state power dissipation rating at TL = 75 °C. Designers should maintain ≥0.25" (6.35 mm) straight lead length and use thermal vias or copper fill to realize this thermal performance in practice. The P6KE150CHE3/73 relies on this parameter for sustained operation under repetitive surge conditions.
