Product details
Overview
P6KE120CHE3/73 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 126 V breakdown voltage (VBR max), 102 V stand-off voltage (VWM), 165 V clamping voltage (VC) at 3.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive engine control units to safeguard microcontrollers against load dump transients.
For engineers reviewing the P6KE120CHE3/73 datasheet, P6KE120CHE3/73 pinout, P6KE120CHE3/73 application, or P6KE120CHE3/73 equivalent, key selection criteria include clamping performance under 3.6 A surge, thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification, RoHS compliance, and unidirectional polarity marking for correct PCB orientation.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 102 V, it avalanches into low-impedance conduction to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response (<1 ns), while the DO-204AC package supports lead-free soldering per J-STD-002 and withstands 275 °C dip for 10 s.
The device is rated for non-repetitive 10/1000 µs surges up to 600 W, with derating above 25 °C ambient per Fig. 2; maximum junction temperature is +175 °C, and thermal resistance from junction to lead is 20 °C/W - enabling direct mounting to copper pours for enhanced thermal management in high-reliability automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 102 V - maximum continuous reverse operating voltage before avalanche onset; defines safe DC rail margin for 12 V/24 V systems. |
| VBR (min/max) | 114 V / 126 V at 1 mA - tight 10.5 % tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | 165 V at 3.6 A - clamping voltage limits stress on protected ICs during ISO 7637-2 Pulse 5a load dump events. |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform enables robust protection against inductive switching spikes. |
| TJ max | +175 °C - extended junction temperature range supports under-hood automotive placement without derating. |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance allows efficient heat transfer to PCB copper, critical for sustained surge duty. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0. Cathode indicated by color band on body; leads are matte tin-plated and solderable per JESD 22-B102.

| Cathode | Avalanche clamping terminal | Marked with color band; connected to protected line (e.g., 24 V rail); clamps reverse transients to ≤165 V. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120A-E3/52 | DO-214AA package; 120 V VWM, 133 V VBR min, 193 V VC @ 3.1 A; 600 W rating; same AEC-Q101/HE3 spec. | Surface-mount alternative with higher VC; requires PCB re-layout but offers better thermal coupling to copper. | Select when space-constrained SMT design prioritizes board area over through-hole serviceability. |
| 1.5KE120A | Same DO-204AC package; 120 V VWM, 133 V VBR min, 193 V VC @ 3.1 A; 1500 W rating; commercial grade only (no AEC-Q101). | Higher power rating but no automotive qualification; larger junction capacitance may affect high-speed signal lines. | Select for cost-sensitive industrial power supplies where AEC-Q101 is not mandated and surge energy exceeds 600 W. |
Compared with SMBJ120A-E3/52 and 1.5KE120A, P6KE120CHE3/73 delivers tighter VBR tolerance (114–126 V vs. 133–147 V), lower clamping voltage (165 V vs. 193 V), and verified AEC-Q101 qualification - making it optimal for automotive-critical 24 V rail protection where voltage margin and reliability are non-negotiable.

FAQ
What is the clamping voltage of P6KE120CHE3/73 and how is it measured?
The clamping voltage (VC) of P6KE120CHE3/73 is 165 V, measured at a peak pulse current (IPPM) of 3.6 A using a 10/1000 µs waveform per Fig. 1 in the datasheet. This value represents the maximum voltage imposed on the protected circuit during a standardized surge event and is guaranteed across temperature and production lot. The P6KE120CHE3/73 achieves this clamping performance due to its low incremental surge resistance and optimized junction design.
Is P6KE120CHE3/73 suitable for automotive applications?
Yes, P6KE120CHE3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments with operating junction temperatures up to +175 °C. Its DO-204AC package, matte tin-plated leads, and JESD 201 Class 2 whisker resistance (HE3 suffix) meet automotive assembly and reliability requirements. The P6KE120CHE3/73 is commonly used in engine control units, body control modules, and ADAS power supplies.
How does the HE3 suffix differ from E3 in P6KE120CHE3/73?
The HE3 suffix in P6KE120CHE3/73 denotes AEC-Q101 qualification, RoHS compliance, and JESD 201 Class 2 whisker resistance - whereas E3 indicates RoHS compliance and commercial-grade qualification only. The HE3 version undergoes additional stress testing (e.g., temperature cycling, HTRB) required for automotive deployment. Both share identical electrical specs, but P6KE120CHE3/73 is the qualified variant for mission-critical systems.
What is the maximum reverse leakage current for P6KE120CHE3/73 at VWM?
The maximum reverse leakage current (ID) for P6KE120CHE3/73 is 1.0 µA at its stand-off voltage (VWM) of 102 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss in standby mode and avoids false triggering in high-impedance circuits. The P6KE120CHE3/73 maintains this specification across its full operating temperature range (-55 °C to +175 °C), verified per the manufacturer's electrical characteristics table.
Can P6KE120CHE3/73 be used in bi-directional configurations?
No, P6KE120CHE3/73 is a uni-directional TVS diode, indicated by the "A" suffix and cathode band marking. Bi-directional variants use the "CA" suffix (e.g., P6KE120CA). Using P6KE120CHE3/73 in bi-directional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect. For AC or dual-polarity signal lines, select a confirmed bi-directional part such as P6KE120CA instead of P6KE120CHE3/73.
