Product details
Overview
P6KE120CHE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for overvoltage protection of sensitive electronics. It features a 114 V minimum breakdown voltage (VBR), 102 V maximum stand-off voltage (VWM), and clamps transients to ≤165 V at 3.6 A peak pulse current (IPPM) under 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the P6KE120CHE3/54 datasheet, P6KE120CHE3/54 pinout, P6KE120CHE3/54 application, or P6KE120CHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 600 W peak pulse power rating, low clamping ratio (VC/VWM ≈ 1.62), and compatibility with high-surge environments where fast response (<1 ns) and robust thermal performance (TJ max = 175 °C) are critical.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (102 V), it avalanches into low-impedance conduction to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive transient stress.
Designed for uni-directional DC line protection, P6KE120CHE3/54 exhibits a maximum reverse leakage of 1.0 µA at VWM, forward voltage of 3.5 V at 50 A (per spec note), and thermal resistance of 20 °C/W (junction-to-lead), enabling effective heat dissipation in compact PCB layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 102 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR (min/max) | 114 V / 126 V - Breakdown occurs within this range at 1.0 mA test current; ensures consistent turn-on threshold. |
| VC @ IPPM | ≤165 V - Clamped voltage during 3.6 A 10/1000 µs surge; determines worst-case stress on protected IC. |
| PPPM | 600 W - Peak pulse power handling capability; supports high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive or industrial enclosures. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; allows direct solder-pad thermal path design without external heatsink. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronic components including temperature cycling and HTRB. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in uni-directional configuration. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail or signal input); avalanche conduction initiates here during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under humidity and thermal cycling. |
| 600 W peak pulse power (10/1000 µs) | Withstands automotive load-dump surges up to ISO 7637-2 Level III (12 V systems) without degradation. |
| AEC-Q101 qualified | Validated for automotive-grade deployment including temperature cycling, HTRB, and ESD testing per JESD22-A114. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., EFT bursts), improving protection margin. |
| RoHS-compliant HE3 suffix | Meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability for safety-critical assemblies. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Shunt TVS placed between power rail and ground to clamp surges above 102 V before reaching MCU or PMIC.

IC Role / Device Role / Timing Role: Uni-directional clamping device on sensor output line referenced to system ground. Use Value: Maintains signal integrity during ESD events (IEC 61000-4-2 ±8 kV contact) while adding <1 pF capacitance to avoid bandwidth reduction. |
| DC-DC Converter Input Stage | Telecom Line Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Lower PPPM (600 W same), but SMC package (higher IPPM = 5.3 A), VC = 177 V at 3.4 A | Preferred for higher board-level surge immunity (IEC 61000-4-5 Level 4) due to superior thermal mass | Select SMBJ110A when layout allows SMC footprint and higher surge margin is required. |
| 1.5KE120A | Same DO-15 package, identical VWM/VBR/VC, but commercial-grade (non-AEC-Q101), 1.5 kW PPPM | Suitable for non-automotive industrial use where qualification is not mandated | Choose 1.5KE120A for cost-sensitive consumer or computing applications without automotive reliability requirements. |
Compared with SMBJ110A and 1.5KE120A, P6KE120CHE3/54 uniquely balances AEC-Q101 compliance, DO-15 form factor, and 600 W surge capability - making it optimal for space-constrained automotive modules requiring validated reliability without SMC-level thermal overhead.

FAQ
What is the clamping voltage of P6KE120CHE3/54 under standard surge conditions?
The P6KE120CHE3/54 clamps to a maximum 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 reflects worst-case voltage seen by protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6KE120CHE3/54 suitable for automotive applications?
Yes, P6KE120CHE3/54 is AEC-Q101 qualified and manufactured with HE3 suffix indicating compliance with JESD201 Class 2 whisker resistance and RoHS requirements. Its 175 °C maximum junction temperature and validation across temperature cycling, HTRB, and ESD tests make it appropriate for under-hood and chassis-mounted automotive modules.
How does the HE3 suffix differ from E3 in P6KE120CHE3/54?
The HE3 suffix denotes AEC-Q101 qualification and JESD201 Class 2 whisker resistance, whereas E3 indicates commercial-grade RoHS compliance only (JESD201 Class 1A). For P6KE120CHE3/54, HE3 confirms automotive suitability, including enhanced process controls and extended reliability testing beyond standard commercial requirements.
What is the thermal resistance of P6KE120CHE3/54, and how does it affect PCB layout?
P6KE120CHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W. This allows efficient heat transfer through the leads to copper pours or chassis connections - meaning no dedicated heatsink is needed, but wide copper traces (≥25 mm² per lead) are recommended to maintain TJ < 175 °C during repetitive surges.
Can P6KE120CHE3/54 be used in bi-directional configurations?
No, P6KE120CHE3/54 is a uni-directional TVS diode, identified by the "A" suffix and cathode band marking. Bi-directional variants require "CA" suffix (e.g., P6KE120CA); using P6KE120CHE3/54 in AC or floating applications risks forward conduction and failure during negative half-cycles.
