Product details
Overview
P6KE120HE3/73 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 102 V stand-off voltage (VWM), 114–126 V breakdown range (VBR at 1 mA), 165 V maximum clamping voltage (VC) at 3.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the P6KE120HE3/73 datasheet, P6KE120HE3/73 pinout, P6KE120HE3/73 application, or P6KE120HE3/73 equivalent, this AEC-Q101 qualified TVS offers validated surge robustness for automotive body electronics, industrial PLC I/O modules, and telecom power supply front-ends where reliability under repetitive transient stress is critical.
Technical Context
The P6KE120HE3/73 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to voltage transients. Its uni-directional polarity uses a cathode band marking and exhibits low incremental surge resistance (< 46 Ω derived from VC/IPPM), ensuring effective clamping during 8.3 ms half-sine or 10/1000 µs surges.
Thermally, it supports operation from –55 °C to +175 °C junction temperature, with 20 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient rating. The device is rated for 100 A non-repetitive forward surge current (IFSM) and dissipates up to 5.0 W continuously on an infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 102 V - Maximum continuous reverse working voltage before significant leakage; sets safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 114–126 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 165 V at 3.6 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; defines protection level. |
| PPPM (Peak Pulse Power) | 600 W - Sustains single high-energy transients without failure; validated per IEC 61000-4-5 Level 4. |
| IPPM (Peak Pulse Current) | 3.6 A - Maximum surge current handled at rated clamping voltage; determines minimum series impedance needed. |
| TJmax | +175 °C - Enables use in under-hood automotive environments and high-temperature industrial enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120A-E3/52 (Vishay) | Same VWM/VBR/VC specs but in SMB (DO-214AA) surface-mount package; 600 W rating retained. | Requires PCB re-layout for SMD placement; better suited for high-density automated assembly. | Select when board space is constrained and reflow compatibility is required over through-hole mounting. |
| 1.5KE120A (Littelfuse) | Identical DO-204AC package and electrical ratings (VWM = 102 V, VC = 165 V), but not AEC-Q101 qualified. | Limited to commercial/industrial use; unsuitable for automotive production without additional qualification. | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with SMBJ120A-E3/52 and 1.5KE120A, the P6KE120HE3/73 uniquely combines AEC-Q101 qualification, axial-leaded DO-15 form factor, and verified 175 °C operation - making it the only option among the three qualified for under-hood automotive deployment without derating.

FAQ
What is the maximum clamping voltage of the P6KE120HE3/73 under standard test conditions?
The P6KE120HE3/73 has a maximum clamping voltage (VC) of 165 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 3.6 A. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings.
Is the P6KE120HE3/73 suitable for automotive applications?
Yes, the P6KE120HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes JESD 201 Class 2 whisker-resistant matte tin plating, operation up to +175 °C junction temperature, and validation across temperature cycling, high-temperature reverse bias, and ESD tests - confirming suitability for body electronics, lighting control, and infotainment power domains.
How does the HE3 suffix differ from the E3 suffix in the P6KE120HE3/73 part number?
The HE3 suffix in P6KE120HE3/73 indicates RoHS compliance plus AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. In contrast, the E3 suffix denotes RoHS compliance and JESD 201 Class 1A whisker resistance but no AEC-Q101 validation. Thus, P6KE120HE3/73 is the only version approved for automotive production without additional component-level qualification.
What is the stand-off voltage (VWM) of the P6KE120HE3/73, and why is it important?
The P6KE120HE3/73 has a stand-off voltage (VWM) of 102 V - the maximum continuous DC or RMS voltage the device can block without significant leakage current (<1 µA). This parameter ensures reliable operation under normal conditions while maintaining sufficient margin below the 114–126 V breakdown range, preventing false triggering during nominal supply fluctuations or ripple.
Can the P6KE120HE3/73 be used in bi-directional configurations?
No, the P6KE120HE3/73 is a uni-directional TVS diode, identifiable by its cathode band marking. Bi-directional variants in the same family use the "CA" suffix (e.g., P6KE120CA). Using P6KE120HE3/73 in bi-directional applications would leave positive-going transients unclamped; correct selection requires matching polarity to circuit topology and transient directionality.
