Product details
Overview
P4KE200HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level overvoltage protection. It features a 171 V standoff voltage (VWM), 190–210 V breakdown range (VBR at 1 mA), 400 W peak pulse power (10/1000 μs), and clamps transients to ≤274 V at 1.5 A peak pulse current - deployed on power rails and I/O lines of automotive ECUs and industrial motor drives.
For engineers reviewing the P4KE200HE3/54 datasheet, P4KE200HE3/54 pinout, P4KE200HE3/54 application, or P4KE200HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, DO-41 mechanical compatibility, and verified clamping performance under 10/1000 μs surge conditions per IEC 61000-4-5.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified VBR range (190–210 V). Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM = 171 V).
It delivers 400 W peak pulse power handling with 10/1000 μs waveform, exhibits 66 °C/W junction-to-lead thermal resistance, and supports 40 A non-repetitive forward surge current (8.3 ms half-sine), making it suitable for transient suppression in DC power inputs and relay coil snubbing.
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 mA - precise avalanche threshold defining turn-on consistency |
| VC @ IPPM | ≤274 V at 1.5 A - clamping voltage limiting downstream component stress during surge |
| PPPM | 400 W - surge energy absorption capability under standardized 10/1000 μs waveform |
| IFSM | 40 A - single half-sine surge current rating (8.3 ms), critical for inductive load switching |
| TJ max | 175 °C - enables operation in under-hood automotive environments and high-ambient industrial settings |
| RθJL | 66 °C/W - low thermal resistance supports reliable power dissipation without heatsinking |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102; cathode indicated by color band on body.

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 (SMB), 200 V VBR, same 400 W PPPM, but lower IPPM (1.4 A vs. 1.5 A) | Surface-mount layout; unsuitable for through-hole designs requiring axial lead strength | Select when board space is constrained and reflow assembly is used. |
| 1.5KE200A | Same DO-41 package, identical VWM/VBR specs, but higher PPPM (1500 W) and larger junction thermal mass | Higher surge margin for infrequent, high-energy events (e.g., utility grid coupling) | Choose when legacy 1.5KE footprint compatibility is required and 1500 W headroom is needed. |
Compared with SMBJ200A, P4KE200HE3/54 offers proven axial-leaded mechanical robustness and AEC-Q101 validation for vibration-prone environments; versus 1.5KE200A, it provides tighter VBR tolerance and lower cost where 400 W suffices.

FAQ
What is the standoff voltage rating of the P4KE200HE3/54?
The P4KE200HE3/54 has a maximum working peak reverse voltage (VWM) of 171 V. This means it remains non-conductive under normal DC or AC peak conditions up to this level, ensuring no leakage or power loss during steady-state operation while remaining ready to clamp transients above its 190–210 V breakdown range.
Is the P4KE200HE3/54 qualified for automotive use?
Yes, the P4KE200HE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification. This includes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - confirming suitability for under-hood and chassis-mounted automotive electronics where reliability under thermal and vibration stress is mandatory.
What does the "HE3/54" suffix mean in P4KE200HE3/54?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies packaging in 13-inch paper tape and reel with 5500 units per reel. This ordering code ensures traceability, automotive-grade process control, and automated placement compatibility.
How does the P4KE200HE3/54 compare to bidirectional TVS diodes?
The P4KE200HE3/54 is unidirectional and must be installed with correct polarity - cathode toward the protected line. Unlike bidirectional variants (e.g., P4KE200CA), it does not conduct on positive transients; thus, it is ideal for DC circuits where only negative-going surges or reverse-polarity faults require suppression, offering tighter VBR control and lower capacitance than equivalent bidirectional parts.
What is the clamping voltage of the P4KE200HE3/54 at rated surge current?
At its rated peak pulse current of 1.5 A (10/1000 μs waveform), the P4KE200HE3/54 clamps to a maximum of 274 V. This value defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings during transient exposure.
