Product details
Overview
P6KE200HE3/73 from Vishay General Semiconductor is a unidirectional 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 standoff voltage (VWM), 274 V maximum clamping voltage at 2.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs to protect CAN transceivers from load dump and inductive switching transients.
For engineers reviewing the P6KE200HE3/73 datasheet, P6KE200HE3/73 pinout, P6KE200HE3/73 application, or P6KE200HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 0.108 %/°C breakdown voltage temperature coefficient, and verified performance under repetitive 0.01 % duty cycle surges - critical for under-hood automotive designs requiring long-term reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its 190–210 V breakdown range (VBR at 1 mA), it transitions from high-impedance blocking to low-impedance conduction within <1 ns, diverting surge current away from downstream ICs. Its glass-passivated junction ensures stable leakage (<1 µA at 171 V) and robust surge handling up to 100 A IFSM (8.3 ms half-sine).
Thermal design relies on RθJL = 20 °C/W (junction-to-lead), enabling effective heat dissipation into PCB copper or chassis mounts. The device's 5.0 W steady-state power rating (at TL = 75 °C) and derating curve support continuous operation in ambient temperatures up to 125 °C when properly heatsinked.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 24 V automotive systems. |
| VBR (min/max) | 190 V / 210 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 274 V at 2.2 A - Clamped voltage under 10/1000 µs surge; limits stress on protected MOSFET gate drivers or microcontroller I/O pins. |
| PPPM | 600 W - Peak pulse power capability; sustains single or repetitive surges per AEC-Q101 test conditions (0.01 % duty cycle). |
| TJ max | 175 °C - Maximum junction temperature; enables deployment in engine control modules and power converters with high thermal loads. |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package; compatible with legacy wave-solder and hand-solder processes. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for under-hood applications. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge events (e.g., reverse polarity connection). |
| Cathode | Reverse-biased clamping terminal | Marked with color band; connected to protected line (e.g., 24 V rail); initiates clamping when voltage exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualification | Validated for automotive use including HTOL, TC, and ESD testing - eliminates need for additional qualification by Tier 1 suppliers. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients; protects 3.3 V/5 V logic interfaces downstream of DC-DC converters. |
| RθJL = 20 °C/W | Enables direct thermal coupling to PCB copper pour or metal chassis; supports >100,000 surge cycles in industrial motor drives. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 24 V supply inputs in engine control units (ECUs) against load dump transients (ISO 16750-2) and alternator ripple.

Use Value: Absorbs 600 W surge energy without failure, reducing reliance on larger, slower secondary protectors and minimizing board space. |
Use Scenario: Shielding BLDC motor driver ICs (e.g., DRV8305) from back-EMF spikes during commutation in washing machine inverters. IC Role / Device Role / Timing Role: Unidirectional clamp on high-side FET source node; suppresses voltage reversal during freewheeling. Use Value: Extends MOSFET lifetime by limiting VDS overshoot to ≤274 V, avoiding avalanche stress beyond rated SOA. |
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 VWM (171 V) and VC (274 V), but SMC package (surface-mount); 600 W rating, AEC-Q101 qualified. | Requires PCB rework for SMT assembly; unsuitable for through-hole legacy designs or high-vibration mechanical retention. | Select SMBJ200A only when migrating to automated SMT production and board space constraints prohibit axial components. |
| 1.5KE200A | Identical electrical specs (VWM, VBR, VC, PPPM) but DO-201AD package; not AEC-Q101 qualified; commercial grade only. | Lacks automotive qualification; limited to industrial/commercial applications where extended temperature cycling is not required. | Choose 1.5KE200A for cost-sensitive non-automotive designs where AEC-Q101 is not mandated and DO-201AD footprint is acceptable. |
Compared with SMBJ200A and 1.5KE200A, P6KE200HE3/73 uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, and proven thermal performance in high-reliability automotive harnesses - making it the default choice for new ECU designs requiring drop-in replaceability and long-term supply stability.

FAQ
What is the maximum clamping voltage of the P6KE200HE3/73 under standard test conditions?
The P6KE200HE3/73 has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current (IPPM) of 2.2 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C 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 P6KE200HE3/73 suitable for automotive applications?
Yes, the P6KE200HE3/73 is AEC-Q101 qualified and specifically designed for automotive use. Its construction includes glass-passivated junctions, matte tin-plated leads compliant with JESD 201 Class 2 whisker resistance, and validated performance across -55 °C to +175 °C operating temperature range - meeting requirements for engine control, body electronics, and ADAS power rail protection.
How does the P6KE200HE3/73 differ from the commercial-grade P6KE200A variant?
The P6KE200HE3/73 differs from P6KE200A primarily in qualification and plating: the HE3 suffix indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas P6KE200A is commercial grade only. Both share identical electrical parameters (VWM, VBR, VC, PPPM), but P6KE200HE3/73 is certified for automotive production and long-term reliability under thermal cycling and humidity stress.
What is the thermal resistance from junction to lead for the P6KE200HE3/73?
The P6KE200HE3/73 has a typical thermal resistance from junction to lead (RθJL) of 20 °C/W. This low value enables efficient heat transfer from the silicon die to the PCB copper or chassis via the leads, supporting sustained operation at elevated ambient temperatures - especially important in enclosed automotive enclosures where airflow is limited.
Can the P6KE200HE3/73 be used in bi-directional protection circuits?
No, the P6KE200HE3/73 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bi-directional applications (e.g., AC lines or differential data buses), the CA-suffixed variant P6KE200CA must be used. Using P6KE200HE3/73 in reverse-biased AC configurations risks forward conduction and failure during negative half-cycles.
