Product details
Overview
P6KE200CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 200 V breakdown voltage (VBR min = 190 V), 274 V maximum clamping voltage at 2.2 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability - used to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients.
For engineers reviewing the P6KE200CHE3/73 datasheet, P6KE200CHE3/73 pinout, P6KE200CHE3/73 application, or P6KE200CHE3/73 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, RoHS-compliant matte tin plating, and compatibility with J-STD-002 solderability standards.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 171 V, it avalanches into low-impedance conduction to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the DO-204AC package supports high surge current handling without thermal runaway.
Designed for single-polarity DC systems, P6KE200CHE3/73 exhibits 3.5 V forward voltage at 50 A (per spec note), 100 A non-repetitive surge rating (8.3 ms half-sine), and temperature coefficient of +0.108 %/°C - enabling predictable derating above 25 °C ambient per Fig. 2 and Fig. 5 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V at 1 mA test current - defines precise avalanche onset range for reliable triggering |
| VWM | 171 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 274 V at 2.2 A peak pulse - clamping voltage limiting stress on protected ICs during 10/1000 µs transients |
| PPPM | 600 W - peak pulse power dissipation capability with 0.01 % duty cycle, enabling robust surge immunity |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for inrush and fault tolerance |
| TJ max | 175 °C - maximum junction temperature supporting operation in under-hood automotive environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead, enabling direct PCB copper pour heatsinking |
Pinout & Package

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 | Same VBR range (190–210 V), but SMB package (surface-mount); lower IPPM (2.1 A vs. 2.2 A), higher VC (281 V) | Requires PCB rework for SMT layout; better suited for space-constrained consumer boards than through-hole automotive harnesses | Select SMBJ200A only if board real estate is constrained and thermal coupling to copper is optimized. |
| 1.5KE200A | Same DO-204AC package and VBR, but 1.5 kW rating (vs. 600 W); higher IPPM (7.4 A), larger package volume (DO-201AD) | Overqualified for most 12 V/24 V systems; requires larger footprint and higher cost; used in heavy-duty industrial drives | Choose 1.5KE200A only when repeated high-energy surges (>1 kV) are expected and PCB layout allows larger body size. |
Compared with SMBJ200A and 1.5KE200A, P6KE200CHE3/73 delivers optimal balance of through-hole mechanical robustness, AEC-Q101 qualification, and 600 W surge capacity in standard DO-15 form - making it the preferred choice for cost-sensitive, high-volume automotive and industrial power rail designs where leaded reliability and proven field performance are prioritized.

FAQ
What is the clamping voltage of P6KE200CHE3/73 at its rated peak pulse current?
The P6KE200CHE3/73 has a maximum clamping voltage (VC) of 274 V at 2.2 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per Figure 1 in the Vishay datasheet 88369 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE200CHE3/73 maintains this clamping performance across its specified operating temperature range.
Is P6KE200CHE3/73 suitable for automotive applications?
Yes, P6KE200CHE3/73 is AEC-Q101 qualified and carries the HE3 suffix indicating compliance with JESD 201 Class 2 whisker testing and automotive material categorization. Its 175 °C maximum junction temperature, glass-passivated junction, and DO-204AC mechanical robustness make it suitable for under-hood and body-control module applications. The P6KE200CHE3/73 meets requirements for load dump and ISO 7637-2 transient immunity in 12 V/24 V vehicle systems.
What does the "HE3" suffix mean in P6KE200CHE3/73?
The "HE3" suffix in P6KE200CHE3/73 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions and confirms compliance with automotive reliability standards, including extended temperature operation and enhanced plating integrity. The P6KE200CHE3/73 HE3 designation is documented in Vishay's ordering information table on page 3 of datasheet 88369.
How does P6KE200CHE3/73 differ from bi-directional P6KE200CA variants?
P6KE200CHE3/73 is a uni-directional TVS diode with cathode marking and forward voltage specification (3.5 V at 50 A), intended for DC rail protection where polarity is fixed. In contrast, P6KE200CA is bi-directional, lacks polarity marking, and has no forward voltage rating - suited for AC or floating signal lines. The P6KE200CHE3/73 cannot replace P6KE200CA in AC-coupled circuits due to asymmetric conduction behavior.
What is the thermal resistance of P6KE200CHE3/73, and how does it affect PCB layout?
The P6KE200CHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning each watt dissipated raises the junction temperature 20 °C above the lead temperature. To maintain reliability, PCB layout should maximize copper area connected to both leads - especially the cathode - to act as a heatsink. The P6KE200CHE3/73 datasheet recommends minimum 0.375" (9.5 mm) lead length for thermal testing, and layout must avoid thermal isolation that could cause premature thermal runaway during repetitive surges.
