Product details
Overview
P6KE12HE3/73 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), 12.6 V maximum breakdown voltage (VBR), 16.7 V maximum clamping voltage (VC) at 35.9 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE12HE3/73 datasheet, P6KE12HE3/73 pinout, P6KE12HE3/73 application, or P6KE12HE3/73 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, thermal resistance (RθJL = 20 °C/W), unidirectional polarity with cathode band marking, and RoHS-compliant AEC-Q101 qualification for automotive electronics protection.
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 avalanches rapidly (<1 ns response) when transient voltage exceeds its 11.4–12.6 V breakdown range. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low temperature coefficient (0.078 %/°C).
Designed for single-pulse and low-duty-cycle repetitive transients, it sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and dissipates 5.0 W continuously on infinite heatsink at TL = 75 °C. The DO-204AC package enables manual or automated through-hole assembly with matte tin-plated leads compliant to J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 11.4 V / 12.6 V - defines precise avalanche initiation window for reliable clamping onset |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | Lower peak power (400 W), SMC package (surface-mount), VC = 19.9 V @ 20.1 A | Better suited for space-constrained PCBs; less robust for high-energy automotive transients | Select SMAJ12A only when board area is critical and surge energy remains below 400 W. |
| 1.5KE12A | Same DO-15 package, higher peak power (1500 W), VC = 19.2 V @ 78.1 A, no AEC-Q101 qualification | Higher energy handling but lacks automotive reliability validation and tighter VBR tolerance | Choose 1.5KE12A for industrial mains input stages where AEC-Q101 is not required. |
Compared with SMAJ12A and 1.5KE12A, the P6KE12HE3/73 delivers optimal balance of AEC-Q101 compliance, 600 W surge capacity, and tight 11.4–12.6 V breakdown control-making it the preferred choice for automotive body control modules and industrial sensor nodes requiring certified reliability.

FAQ
What is the clamping voltage of P6KE12HE3/73 under maximum surge conditions?
The P6KE12HE3/73 exhibits a maximum clamping voltage (VC) of 16.7 V when subjected to its rated 35.9 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and guarantees that protected circuitry sees no more than 16.7 V during worst-case transient events, directly supporting 16 V-rated ICs.
Is P6KE12HE3/73 suitable for automotive applications?
Yes, P6KE12HE3/73 is AEC-Q101 qualified and specifically designed for automotive use. Its construction includes glass-passivated junction, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, and operation up to +175 °C junction temperature-enabling deployment in engine control units, body electronics, and ADAS sensor modules.
How does the HE3 suffix differ from E3 in P6KE12HE3/73?
The HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates commercial-grade RoHS compliance only. P6KE12HE3/73 undergoes additional stress testing-including temperature cycling, highly accelerated life testing (HALT), and mechanical shock-to validate reliability for automotive under-hood environments.
What is the standoff voltage rating for P6KE12HE3/73?
The standoff voltage (VWM) of P6KE12HE3/73 is 10.2 V-the maximum DC or RMS voltage that can be continuously applied without exceeding 5 μA reverse leakage current. This allows safe operation on 9–10 V nominal rails while providing sufficient margin before avalanche onset at 11.4 V minimum breakdown.
Can P6KE12HE3/73 be used in bi-directional protection circuits?
No, P6KE12HE3/73 is a uni-directional TVS diode, identifiable by its cathode band marking. For bi-directional applications (e.g., AC lines or differential data buses), Vishay offers the P6KE12CA variant, which has symmetrical breakdown in both polarities and no polarity marking.
