Product details
Overview
P6KE10CHE3/73 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 600 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, 8.55 V stand-off voltage, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE10CHE3/73 datasheet, P6KE10CHE3/73 pinout, P6KE10CHE3/73 application, or P6KE10CHE3/73 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, surge current handling under IEC 61000-4-5 Level 4, thermal resistance (RθJL = 20 °C/W), and RoHS-compliant AEC-Q101 qualification status.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 8.55 V), but avalanches rapidly when transient voltage exceeds its 9.5–10.5 V breakdown range (IT = 1.0 mA). Its glass-passivated junction ensures stable breakdown and low leakage (<10 μA at VWM).
Designed for unidirectional DC line protection, it uses cathode-band polarity marking and delivers sub-nanosecond response time with low incremental surge resistance-critical for safeguarding MOSFET gates, microcontroller I/O, and sensor supply inputs against ESD and inductive switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 8.55 V - Maximum continuous DC operating voltage before leakage exceeds 10 μA; sets upper limit for protected circuit's nominal rail. |
| Breakdown Voltage (VBR) | 9.5–10.5 V at 1.0 mA - Confirmed avalanche initiation range; defines minimum overvoltage threshold for clamping action. |
| Clamping Voltage (VC) | 14.5 V at 41.4 A (10/1000 μs) - Maximum voltage seen by downstream circuit during worst-case surge; determines required IC absolute maximum rating margin. |
| Peak Pulse Power (PPPM) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; enables compliance with IEC 61000-4-5 Level 4 (4 kV) |
| Thermal Resistance (RθJL) | 20 °C/W - Junction-to-lead thermal path efficiency; supports 5.0 W steady-state dissipation at TL = 75 °C without heatsink. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications per stress test requirements including HTOL, TC, and HAST; suitable for engine control, body electronics, and ADAS power domains. |
| RoHS & Whisker Rating | RoHS compliant (E3/HE3 suffix); HE3 meets JESD 201 Class 2 whisker resistance - ensures long-term solder joint integrity in high-reliability assemblies. |
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/JESD 22-B102. Cathode identified by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes shunt path during avalanche conduction. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 12 V rail or sensor output); avalanche initiates here when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable breakdown voltage across temperature (-55 °C to +175 °C) and lifetime; eliminates parameter drift due to surface contamination. |
| 600 W peak pulse power (10/1000 μs) | Supports robust protection against IEC 61000-4-5 surges up to 4 kV (open-circuit) without degradation; validated at 0.01 % duty cycle. |
| Fast response time (<1 ns) | Clamps transients before sensitive ICs experience overstress; critical for protecting high-speed logic and analog front-ends. |
| AEC-Q101 qualification | Confirms suitability for automotive powertrain, chassis, and infotainment systems where reliability under thermal cycling and humidity is mandatory. |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes voltage overshoot during surge events; reduces risk of latch-up or gate oxide damage in downstream MOSFETs and MCUs. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12 V battery-supplied ECUs exposed to load-dump transients (ISO 7637-2 Pulse 5a, up to 60 V/100 ms). IC Role / Device Role / Timing Role: Shunt clamp placed between VBAT and GND upstream of DC-DC converter input. Use Value: Limits peak voltage to ≤14.5 V during 41.4 A surge, preventing overvoltage failure of buck controller ICs rated for 16 V max. |
Use Scenario: 4–20 mA current-loop transmitter outputs connected to PLC analog inputs in factory automation. IC Role / Device Role / Timing Role: Uni-directional TVS on signal line referenced to local ground, guarding ADC driver stage. Use Value: Clamps ESD (IEC 61000-4-2 ±8 kV contact) and cable-induced surges within 1 ns, preserving 16-bit measurement accuracy. |
| Consumer Device USB Port Protection | Telecom Line Card Surge Suppression |
|
Use Scenario: VBUS line (5 V) in USB 2.0 host ports subjected to hot-plug ESD and capacitive coupling noise. IC Role / Device Role / Timing Role: Primary protection device placed immediately after USB connector, before polyfuse and port controller. Use Value: Withstands ±15 kV air discharge (IEC 61000-4-2) while maintaining <10 μA leakage at 5 V, avoiding false disconnect detection. |
Use Scenario: Tip/ring lines in VoIP gateway FXS interfaces exposed to lightning-induced surges (ITU-T K.20/21). IC Role / Device Role / Timing Role: First-stage protector on line side of transformer, coordinated with gas discharge tube (GDT) secondary stage. Use Value: Fast clamping (≤14.5 V) prevents semiconductor damage before GDT fires; RθJL = 20 °C/W enables reliable thermal recovery between surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same VWM (8.55 V) and VC (14.5 V), but SMC package (higher PPPM = 600 W, lower RθJA = 40 °C/W vs. DO-15's 75 °C/W) | Preferred for higher board-level power density and improved thermal performance in space-constrained industrial PCBs. | Select SMBJ10A when layout allows SMC footprint and enhanced thermal management is required for repeated surge events. |
| 1.5KE10A | Same DO-204AC package and electrical specs, but commercial-grade only (no AEC-Q101 qualification); identical VBR, VC, and PPPM | Suitable for non-automotive applications where AEC-Q101 is not mandated (e.g., consumer power adapters, office equipment). | Choose 1.5KE10A for cost-sensitive commercial designs where automotive qualification is unnecessary and DO-15 footprint must be retained. |
Compared with SMBJ10A, P6KE10CHE3/73 offers AEC-Q101 validation and tighter manufacturing controls for automotive use, while 1.5KE10A provides identical protection performance at lower cost for non-automotive deployments-enabling tiered sourcing without redesign.

The P6KE10CHE3/73 maintains this specification under AEC-Q101 stress conditions.
Is the P6KE10CHE3/73 suitable for automotive applications?
Yes, the P6KE10CHE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its HE3 suffix denotes compliance with JESD 201 Class 2 whisker resistance and full AEC-Q101 stress testing-including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. The P6KE10CHE3/73 is deployed in engine control units, body control modules, and ADAS power domains.
What is the maximum clamping voltage of the P6KE10CHE3/73 under surge conditions?
The P6KE10CHE3/73 clamps to a maximum of 14.5 V when subjected to a 10/1000 μs waveform peak pulse current of 41.4 A. This value is specified in the Vishay datasheet (Document Number 88369, page 2) and represents the worst-case voltage imposed on protected circuitry during standardized surge events such as IEC 61000-4-5.
Does the P6KE10CHE3/73 have RoHS and lead-free compliance?
Yes, the P6KE10CHE3/73 is RoHS compliant per Directive 2011/65/EU and features matte tin-plated leads. The "HE3" suffix confirms compliance with JESD 201 Class 2 whisker resistance testing, and the molding compound meets UL 94 V-0 flammability standards. All materials documentation is accessible via Vishay's Material Category Policy (Doc. 99912).
How does the P6KE10CHE3/73 differ from the P6KE10A variant?
The P6KE10CHE3/73 differs from the base P6KE10A by its AEC-Q101 qualification (denoted by "H"), RoHS-compliant HE3 plating (Class 2 whisker resistance), and tighter process controls for automotive use. Electrically, both share identical VWM, VBR, VC, and PPPM specs-but only the P6KE10CHE3/73 carries automotive-grade validation and traceable lot-level qualification data.
