Product details
Overview
P6KE36HE3/73 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 a 34.2 V minimum breakdown voltage (VBR), 30.8 V maximum stand-off voltage (VWM), 49.9 V clamping voltage (VC) at 12.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial sensor interfaces, and telecom power input stages.
For engineers reviewing the P6KE36HE3/73 datasheet, P6KE36HE3/73 pinout, P6KE36HE3/73 application, or P6KE36HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, 1.0 µA max reverse leakage at VWM, and compatibility with lead-free reflow and wave soldering per J-STD-002/JESD 22-B102.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 GΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR. Its glass-passivated junction ensures stable avalanche characteristics and repeatable clamping performance across 1000+ surge events.
The device is rated for 100 A non-repetitive forward surge current (IFSM) and exhibits a +0.099 %/°C temperature coefficient of VBR, enabling predictable derating above 25 °C ambient. Thermal resistance from junction to lead is 20 °C/W, supporting reliable operation without heatsinking in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA; defines safe DC rail margin |
| VBR (min/max) | 34.2 V / 37.8 V at 1.0 mA test current - guaranteed avalanche initiation range; determines earliest clamping onset |
| VC @ IPPM | 49.9 V at 12.0 A (10/1000 µs) - maximum clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capability; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity |
| TJ max | 175 °C - maximum junction temperature; enables use in under-hood automotive environments and sealed industrial enclosures |
| RoHS / AEC-Q101 | RoHS-compliant (E3/HE3 suffix) and AEC-Q101 qualified - certified for automotive electronics and industrial-grade reliability |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during positive transients when cathode is biased higher |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 24 V rail or signal input); initiates clamping when voltage exceeds VBR relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, low-drift avalanche characteristics over 1000+ surge cycles and 15-year service life |
| 600 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 combination wave surges up to 4 kV without degradation |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage stress on downstream ICs - critical for protecting 3.3 V/5 V logic and MOSFET gate drivers |
| 175 °C junction rating | Enables direct placement near heat sources (e.g., power converters) without thermal derating penalties |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamping |
|---|---|

Use Scenario: 12 V/24 V battery-fed ECU inputs exposed to load-dump (ISO 16750-2) and jump-start transients. IC Role / Device Role / Timing Role: Shunt clamping element placed between supply rail and ground, triggered within <1 ns to limit voltage to ≤49.9 V. Use Value: Prevents destruction of MCU power management ICs and CAN transceivers during 120 V/400 ms load-dump events. |
Use Scenario: Analog output lines (e.g., 4–20 mA current loop or 0–10 V sensor outputs) in factory automation PLC modules. IC Role / Device Role / Timing Role: Bidirectional protection (when used with companion diode) or uni-directional rail clamp against ESD and inductive switching noise. Use Value: Maintains signal integrity below ±15 V common-mode noise while surviving 8 kV contact ESD (IEC 61000-4-2). |
| Telecom DC Power Entry Stage | Consumer Appliance Motor Drive Protection |
|
Use Scenario: -48 V DC power feed to base station radios and optical line terminals subject to lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of DC/DC converter, coordinated with MOV and fuse. Use Value: Limits transient voltage to <50 V during 10/1000 µs surges, preventing latch-up in PMICs and protecting GaN FET gate oxide. |
Use Scenario: Brushed DC motor driver PCBs in washing machines and HVAC blowers, where back-EMF spikes exceed 100 V. IC Role / Device Role / Timing Role: Clamp across motor terminals or H-bridge supply rails to absorb inductive kickback energy. Use Value: Eliminates need for snubber RC networks; reduces board space by 40% vs. discrete Zener+capacitor solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | DO-214AA package; 36.0 V VBR min; 58.1 V VC @ 10.3 A; 600 W rating; same AEC-Q101 qualification | Surface-mount footprint; lower thermal resistance (RθJA = 40 °C/W vs. 75 °C/W); better suited for high-density PCBs | Select SMBJ36A when automated SMT assembly, smaller board area, or improved thermal performance is required. |
| 1.5KE36A | DO-201AD package; identical VBR/VC specs; 1500 W PPPM; no AEC-Q101 qualification; higher leakage (5.0 µA) | Higher surge capacity for infrequent, high-energy events (e.g., AC mains coupling); not automotive-qualified | Choose 1.5KE36A only for cost-sensitive industrial equipment where AEC-Q101 is unnecessary and surge duty cycle is low. |
Compared with SMBJ36A and 1.5KE36A, P6KE36HE3/73 offers optimal balance of AEC-Q101 compliance, axial-leaded through-hole robustness, and proven field reliability in automotive and harsh industrial environments - making it preferred for long-lifecycle, safety-critical deployments where manual assembly or mechanical stress tolerance matters.

FAQ
What is the clamping voltage of P6KE36HE3/73 and how is it measured?
The clamping voltage (VC) of P6KE36HE3/73 is 49.9 V, measured at 12.0 A peak pulse current using a standardized 10/1000 µs double-exponential waveform per IEC 61000-4-5. This value represents the maximum voltage imposed on the protected circuit during a surge event and is verified at TA = 25 °C with specified test conditions in the Vishay datasheet 88369.
Is P6KE36HE3/73 suitable for automotive applications?
Yes, P6KE36HE3/73 is AEC-Q101 qualified (HE3 suffix), meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and surge endurance required for automotive electronics. It is widely used in engine control modules, body control units, and ADAS sensor power supplies where reliability under vibration and thermal cycling is critical.
What does the "HE3" suffix mean in P6KE36HE3/73?
The "HE3" suffix in P6KE36HE3/73 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this automotive-grade variant from commercial "E3" versions (e.g., P6KE36AE3/73), which lack AEC-Q101 validation and are intended for industrial or consumer applications.
How does P6KE36HE3/73 compare to P6KE36A in terms of reliability?
P6KE36HE3/73 provides enhanced reliability over standard P6KE36A due to AEC-Q101 qualification, stricter process controls, and extended lifetime testing under automotive stress profiles. While both share identical electrical specs, P6KE36HE3/73 undergoes additional qualification including 1000-hour HTOL, temperature humidity bias, and surge endurance cycling - ensuring robustness in mission-critical automotive systems.
Can P6KE36HE3/73 be used in bi-directional protection circuits?
No, P6KE36HE3/73 is a uni-directional TVS diode, identifiable by its cathode band marking. For bi-directional protection, Vishay specifies CA-suffix variants (e.g., P6KE36CA). Using P6KE36HE3/73 in reverse-biased configurations risks permanent damage, as it is not rated for reverse conduction beyond VWM.
