Product details
Overview
P6KE56CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 53.2 V minimum breakdown voltage (VBR), 47.8 V maximum stand-off voltage (VWM), 77.0 V clamping voltage (VC) at 7.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the P6KE56CHE3/73 datasheet, P6KE56CHE3/73 pinout, P6KE56CHE3/73 application, or P6KE56CHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, 175 °C max junction temperature, and verified clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (47.8 V), it avalanches into low-impedance conduction to divert surge current away from downstream ICs. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and fast response (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling reliable operation up to 175 °C junction temperature. The device sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 0.103 %/°C VBR temperature coefficient - essential for high-temperature automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 47.8 V maximum - defines maximum continuous DC operating voltage before leakage exceeds 1 µA; sets safe margin below system rail (e.g., 48 V nominal bus) |
| VBR @ IT = 1 mA | 53.2–58.8 V - breakdown threshold where device enters avalanche; used to verify minimum protection level against overvoltage events |
| VC @ IPPM = 7.8 A | 77.0 V - clamped voltage during 600 W transient; determines maximum stress imposed on protected circuitry |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform; validates robustness against IEC 61000-4-5 Level 4 surges |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms); supports protection of power converters subject to load dump transients |
| TJ max | 175 °C - maximum junction temperature; enables use in under-hood automotive modules without derating penalties |
| Package | DO-204AC (DO-15) - axial-leaded through-hole package with 0.300" lead spacing; compatible with legacy PCB layouts and wave soldering |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with matte tin-plated leads; cathode indicated by color band on one end; meets UL 94 V-0 flammability rating and J-STD-002 solderability standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or low-side return path in uni-directional clamp configuration |
| Cathode | Current exit point during reverse-biased avalanche | Connected to protected line (e.g., +12 V rail); color band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control units and ADAS power supplies |
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and low leakage (<1 µA at VWM) across -55 °C to +175 °C operating range |
| 600 W peak pulse power | Withstands 10/1000 µs surges up to 7.8 A - meets IEC 61000-4-5 Level 4 (4 kV) requirements for industrial equipment |
| Fast response time | <1 ns turn-on - limits voltage overshoot during nanosecond-scale ESD or switching transients on data lines |
| Low incremental surge resistance | Minimizes VC rise under high-current pulses - preserves margin between clamped voltage and protected IC's absolute maximum rating |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
|
Use Scenario: 12 V battery-fed ECUs exposed to load dump transients (ISO 7637-2 Pulse 5a, up to 60 V/100 ms). IC Role / Device Role: Primary shunt clamp on main power rail upstream of DC/DC converter input. Use Value: Limits rail voltage to ≤77.0 V during 600 W surge, preventing damage to buck controller ICs rated for 80 V max input. |
Use Scenario: 4–20 mA current loop interface in factory automation PLC modules subjected to field wiring ESD. IC Role / Device Role: Uni-directional TVS placed across loop terminals to suppress ±8 kV contact discharge (IEC 61000-4-2). Use Value: Clamps transients within 1 ns while maintaining <1 µA leakage at 24 V - avoids signal offset or loop error. |
| Consumer Device USB Port Surge Guard | Telecom Power Supply Inrush Limiter |
|
Use Scenario: USB 2.0 VBUS line in set-top boxes connected to unshielded cables in noisy home environments. IC Role / Device Role: Standoff-limited TVS (VWM = 47.8 V) placed between VBUS and chassis ground. Use Value: Blocks 100 V lightning-induced surges while remaining inactive during normal 5 V operation - no standby power loss. |
Use Scenario: Secondary-side 48 V output of telecom rectifier subjected to AC line transients coupled via transformer. IC Role / Device Role: Low-capacitance TVS on output rail to protect downstream PoE controllers and Ethernet PHYs. Use Value: Delivers 600 W surge absorption without degrading 48 V regulation - maintains tight ±1 % output tolerance during fault. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A | Lower peak pulse power (400 W), SMA package (SMT), 58 V VBR min, 50 V VWM | Designed for space-constrained SMT layouts; not AEC-Q101 qualified; higher thermal resistance (RθJA ≈ 110 °C/W) | Select for cost-sensitive consumer boards where board area is limited and automotive qualification is unnecessary. |
| 1.5KE56A | Same DO-15 package, 600 W rating, but commercial-grade only (not AEC-Q101); 53.2–58.8 V VBR, 47.8 V VWM | Lacks automotive qualification and whisker-tested leads; identical electrical specs but lower reliability assurance for harsh environments | Use in industrial controls or test equipment where AEC-Q101 is not mandated and lifecycle continuity is less critical. |
Compared with SMAJ58A and 1.5KE56A, P6KE56CHE3/73 uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and 175 °C junction rating - making it the preferred choice for automotive power modules requiring long-term reliability and serviceability.

FAQ
What is the maximum clamping voltage of the P6KE56CHE3/73 under a 600 W transient?
The P6KE56CHE3/73 clamps to a maximum of 77.0 V when subjected to its rated 7.8 A peak pulse current (10/1000 µs waveform). This value is measured per JEDEC standards and represents the upper limit of voltage seen by protected circuitry during worst-case surge events - critical for ensuring downstream ICs remain within their absolute maximum voltage ratings.
Is the P6KE56CHE3/73 suitable for automotive applications?
Yes, the P6KE56CHE3/73 is AEC-Q101 qualified and features matte tin-plated leads meeting JESD 201 Class 2 whisker testing. Its 175 °C maximum junction temperature, glass-passivated junction, and validated surge performance make it appropriate for under-hood ECUs, body control modules, and ADAS power supplies where reliability under thermal and electrical stress is mandatory.
How does the P6KE56CHE3/73 differ from the standard P6KE56A variant?
The P6KE56CHE3/73 differs from P6KE56A by its HE3 suffix: it is RoHS-compliant, AEC-Q101 qualified, and undergoes JESD 201 Class 2 whisker testing. The base P6KE56A is commercial-grade only. Both share identical electrical specs (VBR, VC, PPPM), but P6KE56CHE3/73 adds automotive-grade process controls and extended reliability validation.
What is the standoff voltage rating for the P6KE56CHE3/73?
The P6KE56CHE3/73 has a maximum stand-off voltage (VWM) of 47.8 V - the highest DC or RMS voltage that can be continuously applied without exceeding 1 µA reverse leakage current. This allows safe integration into 48 V nominal systems while preserving margin against ripple and tolerance drift.
Can the P6KE56CHE3/73 be used in bi-directional protection circuits?
No, the P6KE56CHE3/73 is a uni-directional TVS diode, indicated by the "A" suffix and cathode band marking. For bi-directional applications (e.g., AC lines or differential data buses), the P6KE56CA variant must be used - it provides symmetrical clamping in both polarities and lacks polarity marking.
