Product details
Overview
P4KE200HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 171 V stand-off voltage (VWM), 190–210 V breakdown voltage (VBR), 274 V maximum clamping voltage (VC) at 1.5 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform-used to safeguard MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the P4KE200HE3/73 datasheet, P4KE200HE3/73 pinout, P4KE200HE3/73 application, or P4KE200HE3/73 equivalent, key selection criteria include clamping performance under 10/1000 µs transients, AEC-Q101 qualification for automotive reliability, DO-41 mechanical compatibility, and thermal resistance (RθJL = 66 °C/W) for board-level thermal design.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown to clamp transient overvoltages above its VWM threshold while maintaining low leakage (<1.0 µA at 171 V). Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1.0 ns), enabling effective suppression of ESD, inductive switching spikes, and lightning-induced surges.
Rated for 175 °C maximum junction temperature and qualified to AEC-Q101, the P4KE200HE3/73 supports high-reliability automotive applications. Its 1.5 W steady-state power dissipation and 66 °C/W junction-to-lead thermal resistance allow direct PCB mounting without heatsinking for moderate-duty transient events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 190 V / 210 V at 1.0 mA - Ensures predictable, tight-breakdown activation across production lots |
| VC @ IPPM | 274 V at 1.5 A - Clamping voltage limits downstream component stress during 10/1000 µs surge |
| PPPM | 400 W - Peak pulse power handling capability per single 10/1000 µs transient event |
| IFSM | 40 A - Surge current rating for 8.3 ms half-sine wave, critical for inductive load switching protection |
| TJ max. | 175 °C - Enables operation in under-hood automotive environments and industrial enclosures |
| RθJL | 66 °C/W - Junction-to-lead thermal resistance supports thermal management without added heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | DO-214AA package; 200 V VWM; 322 V VC at 1.23 A; 600 W PPPM | Higher power density but larger footprint; requires different PCB layout | Select SMBJ200A when higher surge margin or surface-mount assembly is required. |
| 1.5KE200A | DO-201AD package; same VWM/VBR specs; 274 V VC at 1.5 A; 1500 W PPPM | Larger case size and higher IPPM capacity; not AEC-Q101 qualified | Choose 1.5KE200A for non-automotive applications needing higher single-pulse energy absorption. |
Compared with SMBJ200A and 1.5KE200A, the P4KE200HE3/73 offers AEC-Q101 qualification and DO-41 through-hole compatibility ideal for legacy automotive modules and industrial controls where mechanical robustness and serviceability matter-without requiring requalification for existing designs.

FAQ
What is the clamping voltage of the P4KE200HE3/73 under standard test conditions?
The P4KE200HE3/73 has a maximum clamping voltage (VC) of 274 V at 1.5 A peak pulse current using a 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events-critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P4KE200HE3/73 suitable for automotive applications?
Yes, the P4KE200HE3/73 is AEC-Q101 qualified and manufactured with HE3 suffix indicating compliance with JESD 201 Class 2 whisker resistance and RoHS requirements. Its 175 °C maximum junction temperature and tested performance under repetitive surge conditions make it appropriate for engine control modules, body controllers, and ADAS sensor interfaces.
How does the P4KE200HE3/73 differ from the commercial-grade P4KE200A-E3/73?
The P4KE200HE3/73 differs from P4KE200A-E3/73 primarily in qualification level: HE3 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker testing, whereas E3 is commercial grade with Class 1A whisker resistance. Both share identical electrical specs and DO-41 packaging, but only the HE3 variant is approved for automotive use.
What is the thermal resistance of the P4KE200HE3/73, and how does it affect PCB layout?
The P4KE200HE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W. This enables effective heat transfer from the die to PCB copper via the leads-so generous copper pour around anode/cathode pads and ≥9.5 mm lead length significantly improve sustained power handling without external heatsinking.
Can the P4KE200HE3/73 be used in bidirectional configurations?
No, the P4KE200HE3/73 is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection, Vishay specifies CA-suffix variants (e.g., P4KE200CA); using P4KE200HE3/73 in reverse-biased mode risks permanent breakdown due to lack of symmetrical avalanche structure.
