Product details
Overview
P6KE150HE3/73 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 V clamping voltage (VC) at 2.9 A peak pulse current, 600 W peak pulse power rating with 10/1000 μs waveform, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE150HE3/73 datasheet, P6KE150HE3/73 pinout, P6KE150HE3/73 application, or P6KE150HE3/73 equivalent, this device is selected for robust surge immunity in automotive power modules, industrial sensor interfaces, and telecom line protection where stable clamping performance under repetitive transients and lead-free RoHS-compliant assembly are required.
Technical Context
This TVS diode employs a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its uni-directional polarity enables integration into DC-biased circuits without reverse conduction during normal operation, while maintaining symmetrical clamping behavior under positive transients.
The device operates across -55 °C to +175 °C junction temperature range and exhibits a +0.108 %/°C temperature coefficient of breakdown voltage - enabling predictable voltage derating in high-temperature environments such as engine control units or power supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 128 V maximum - ensures reliable blocking of normal operating voltage with ≥15 % margin below minimum breakdown. |
| VBR (min/max) | 143 V / 158 V at 1 mA - defines precise voltage threshold for avalanche conduction onset under transient stress. |
| VC @ IPPM | 207 V at 2.9 A - limits worst-case voltage seen by protected ICs during 10/1000 μs surge events. |
| PPPM | 600 W - sustains high-energy lightning-induced surges per IEC 61000-4-5 Level 4 without degradation. |
| IFSM | 100 A (8.3 ms half-sine) - withstands inrush currents and short-circuit fault conditions in power distribution networks. |
| TJ max | +175 °C - supports placement near heat-generating components in automotive and industrial enclosures. |
| RθJL | 20 °C/W - enables effective thermal coupling to PCB copper pour or heatsinked leads for sustained power dissipation. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards. The cathode is marked by a color band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to circuit ground or lowest potential node; conducts during positive transients when cathode is at higher potential. |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V rail); avalanche conduction initiates here when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables <1 ns response time and stable leakage performance across temperature and humidity stress. |
| AEC-Q101 qualified | Validated for automotive applications including powertrain, body electronics, and ADAS sensor interfaces. |
| 600 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge immunity requirements for industrial and automotive equipment. |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance for long-term reliability in lead-free reflow. |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation suitable for enclosed systems requiring safety certification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Same VWM/VBR/VC ratings but SMC (DO-214AB) surface-mount package; 600 W rating at 10/1000 μs; lower RθJA (50 °C/W). | Requires PCB redesign for SMT layout; better suited for high-density consumer electronics vs. through-hole industrial modules. | Select SMBJ150A when board space is constrained and automated assembly is preferred over manual leaded insertion. |
| 1.5KE150A | Same DO-204AC package and electrical specs but commercial-grade (non-AEC-Q101); 1.5 kW peak power rating (10/1000 μs); higher IPPM (9.4 A). | Lacks automotive qualification; used in cost-sensitive industrial controls where extended temperature validation is not required. | Select 1.5KE150A only for non-automotive applications where higher single-pulse energy tolerance is prioritized over long-term reliability under thermal cycling. |
Compared with SMBJ150A and 1.5KE150A, P6KE150HE3/73 uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, and optimized thermal resistance (RθJL = 20 °C/W) for mechanically robust, high-reliability power rail protection in harsh environments.

FAQ
What is the clamping voltage of P6KE150HE3/73 and how does it protect downstream components?
The P6KE150HE3/73 has a maximum clamping voltage (VC) of 207 V at 2.9 A peak pulse current (10/1000 μs waveform). This value represents the highest voltage that will appear across the protected line during a standardized surge event. By limiting transient voltage to this level, the P6KE150HE3/73 prevents overstress of downstream components such as MOSFET gate oxides, microcontroller I/O pins, and DC/DC converter input stages - ensuring functional integrity after exposure to IEC 61000-4-5 Level 4 surges.
Is P6KE150HE3/73 suitable for automotive applications?
Yes, P6KE150HE3/73 is AEC-Q101 qualified and specifically rated for automotive use. Its construction includes glass-passivated junction, JESD 201 Class 2 whisker-resistant matte tin plating, and operation up to +175 °C junction temperature - meeting requirements for engine bay, powertrain, and body control module deployments. The HE3 suffix explicitly denotes this qualification status per Vishay's ordering nomenclature.
How does the VWM of 128 V relate to system operating voltage selection for P6KE150HE3/73?
The 128 V maximum stand-off voltage (VWM) defines the highest continuous DC or RMS voltage the P6KE150HE3/73 can block without entering avalanche conduction. For reliable operation, system nominal voltage must remain at least 15–20 % below VWM; thus, P6KE150HE3/73 is appropriate for 100 V DC bus systems (e.g., 48 V telecom backup supplies or 24 V industrial controls with high-voltage transients), ensuring no leakage or thermal runaway during steady-state conditions.
What is the meaning of the 'HE3' suffix in P6KE150HE3/73?
The 'HE3' suffix in P6KE150HE3/73 indicates two key attributes: 'H' denotes AEC-Q101 qualification, and 'E3' specifies RoHS compliance with JESD 201 Class 2 whisker resistance. The '/73' denotes packaging in 7-inch tape-and-reel format (4000 pcs/reel). This distinguishes it from commercial-grade variants like P6KE150A-E3/54 and confirms suitability for automotive and high-reliability industrial applications.
Can P6KE150HE3/73 be used in bi-directional protection circuits?
No, P6KE150HE3/73 is a uni-directional TVS diode, identifiable by its cathode band marking and specified electrical characteristics for forward-biased avalanche only. For bi-directional protection (e.g., AC lines or ungrounded signal pairs), Vishay offers CA-suffixed variants such as P6KE150CA. Using P6KE150HE3/73 in bi-directional configurations would result in unintended conduction during negative transients and possible device failure.
