Product details
Overview
P6KE12CHE3/73 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 sensitive electronics. It features 600 W peak pulse power (10/1000 μs), 16.7 V maximum clamping voltage at 35.9 A peak pulse current, and 12.6 V maximum breakdown voltage at 1 mA test current - deployed in automotive sensor signal lines, industrial I/O ports, and DC power rail protection.
For engineers reviewing the P6KE12CHE3/73 datasheet, P6KE12CHE3/73 pinout, P6KE12CHE3/73 application, or P6KE12CHE3/73 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, standoff voltage compatibility with operating rail (10.2 V max VWM), AEC-Q101 qualification status, and thermal resistance (RθJL = 20 °C/W) for sustained surge handling.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 10.2 V), but triggers into low-impedance conduction when transient voltage exceeds its 11.4–12.6 V breakdown range. Its glass-passivated junction enables fast response (<1 ns) and stable leakage performance (≤5.0 μA at VWM).
Designed for single-pulse and low-duty-cycle repetitive transients, it sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and derates linearly above 25 °C ambient per Fig. 2. The device's 20 °C/W junction-to-lead thermal resistance supports reliable power dissipation up to 5.0 W on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 11.4 V / 12.6 V at 1 mA - defines precise voltage threshold where clamping begins; ensures robust margin below 13.5 V automotive battery transients |
| VWM | 10.2 V max - maximum continuous working voltage; must exceed system nominal rail (e.g., 9–10 V automotive sensors) |
| VC @ IPPM | 16.7 V at 35.9 A - clamping voltage during 600 W surge; determines peak stress on downstream ICs |
| IPPM | 35.9 A (10/1000 μs) - peak surge current capacity; validates protection against ISO 7637-2 Pulse 1/2a/5a waveforms |
| PPPM | 600 W - standardized surge power rating; confirms suitability for CAN/LIN bus and 12 V power line protection |
| TJ max | +175 °C - maximum junction temperature; enables operation in under-hood automotive environments |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; supports PCB trace heat sinking without external heatsink |
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 solderability and JESD 201 Class 2 whisker resistance (HE3 suffix). Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | Same VBR range (11.4–12.6 V), lower PPPM (400 W), SMA package (surface-mount) | Requires PCB rework for SMT layout; unsuitable for through-hole legacy designs or high-vibration mounting | Select when board space is constrained and automated assembly is required. |
| 1.5KE12A | Higher PPPM (1500 W), same DO-15 package, higher VC (20.1 V), no AEC-Q101 qualification | Acceptable for industrial power supplies but not validated for automotive temperature cycling or humidity testing | Select when higher surge margin is needed and automotive qualification is not required. |
Compared with SMAJ12A and 1.5KE12A, the P6KE12CHE3/73 uniquely balances AEC-Q101 compliance, 600 W capability, and through-hole DO-15 form factor - making it optimal for automotive sensor modules and industrial field devices requiring mechanical robustness and qualification traceability.

FAQ
What does the 'HE3' suffix indicate in P6KE12CHE3/73?
The HE3 suffix in P6KE12CHE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. This distinguishes it from commercial-grade E3 variants and confirms suitability for automotive applications including engine control, chassis, and ADAS subsystems where reliability under thermal and vibration stress is mandatory. The P6KE12CHE3/73 meets all test requirements defined in AEC-Q101 Rev D.
How does P6KE12CHE3/73 differ from bi-directional P6KE12CA variants?
The P6KE12CHE3/73 is a uni-directional TVS diode with cathode marking and asymmetric conduction - it clamps only positive transients relative to ground. In contrast, P6KE12CA is bi-directional and suppresses both polarities, making it suitable for AC lines or differential buses. The P6KE12CHE3/73 offers tighter VBR tolerance (11.4–12.6 V vs. 11.1–13.4 V for CA) and lower clamping voltage (16.7 V vs. ~17.5 V), optimizing protection for single-rail DC systems.
Can P6KE12CHE3/73 be used for ESD protection per IEC 61000-4-2?
Yes, the P6KE12CHE3/73 provides effective system-level ESD protection due to its sub-nanosecond response time and low clamping voltage (16.7 V at 35.9 A), which aligns with IEC 61000-4-2 Level 4 (8 kV contact / 15 kV air) requirements when properly laid out with minimal trace inductance. However, for component-level ESD immunity, dedicated ESD arrays (e.g., USB-IF certified devices) are recommended - the P6KE12CHE3/73 serves best as secondary or board-level protection.
What is the maximum allowable lead temperature during soldering for P6KE12CHE3/73?
The P6KE12CHE3/73 supports solder dip at 275 °C maximum for 10 seconds per JESD 22-B106, and its matte tin-plated leads comply with J-STD-002 for solderability. Reflow profiles must stay within JEDEC J-STD-020 moisture sensitivity level (MSL) 1 limits - though as a non-MOISTURE-SENSITIVE device, P6KE12CHE3/73 has no floor life restriction and may be processed without baking.
Is thermal derating required for P6KE12CHE3/73 in high-temperature environments?
Yes - the P6KE12CHE3/73 must be derated above 25 °C ambient per Figure 2 in Vishay document 88369. At 85 °C ambient, its peak pulse power drops to ~75 % of 600 W (≈450 W), and at 125 °C, it falls to ~50 % (≈300 W). Designers must verify clamping performance under worst-case junction temperature (TJ ≤ 175 °C) using RθJL = 20 °C/W and actual lead temperature measurements, especially in sealed enclosures or near heat sources.
