Product details
Overview
P6KE56CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 56 V breakdown voltage (VBR min/max = 53.2–58.8 V), 77.0 V maximum clamping voltage at 7.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE56CA-E3/54 datasheet, P6KE56CA-E3/54 pinout, P6KE56CA-E3/54 application, or P6KE56CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and low leakage (<1.0 μA at 47.8 V stand-off).
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche breakdown in both polarities. Its glass-passivated junction enables fast response time (<1.0 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01% duty cycle.
Designed for unclamped inductive switching events and lightning-induced surges, it maintains clamping performance across -55 °C to +175 °C junction temperature range and supports soldering per JESD 22-B106 (275 °C, 10 s). The DO-15 package provides UL 94 V-0 rated epoxy encapsulation and matte tin-plated leads compliant with J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 53.2 V / 58.8 V at 1.0 mA test current - defines reliable avalanche initiation threshold in both directions |
| VWM | 47.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 77.0 V at 7.8 A - clamping voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 600 W - peak transient power handling without degradation under standardized waveform |
| IFSM | Not applicable - bidirectional device has no forward surge rating (unidirectional only) |
| TJ max | +175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pour design |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case with UL 94 V-0 flammability rating. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Either terminal serves as input/output - identical clamping behavior in both directions |
| Lead 1 / Lead 2 | Thermal and electrical interface | Matte tin-plated, solderable per J-STD-002; primary heat path to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables <1.0 ns response time and stable long-term leakage performance under thermal cycling |
| 600 W peak pulse power (10/1000 μs) | Supports protection against ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surges |
| AEC-Q101 qualified (HE3 suffix variant) | P6KE56CA-E3/54 is commercial grade; HE3 variant meets automotive reliability requirements |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage exposure to protected ICs while maintaining margin above VWM |
| UL 94 V-0 molding compound | Ensures flame retardancy in enclosed industrial enclosures and automotive junction boxes |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between power rail and ground. Use Value: Limits transients to ≤77.0 V during 7.8 A surges, preventing latch-up in microcontrollers and CAN transceivers. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on differential or single-ended signal lines. Use Value: Sub-μA leakage at 47.8 V ensures minimal impact on 24-bit ADC reference accuracy and offset stability. |
| Telecom Line Surge Suppression | Consumer Appliance Motor Control |
Use Scenario: Guarding RS-485/RS-232 ports against induced lightning surges on long cable runs. IC Role / Device Role / Timing Role: Primary line-to-ground TVS on data port PCB edge. Use Value: 600 W rating handles IEC 61000-4-5 combination wave (10/700 μs) up to 4 kV with margin. |
Use Scenario: Suppressing inductive kickback from brushed DC motors in washing machines or HVAC blowers. IC Role / Device Role / Timing Role: Across-motor terminals to clamp back-EMF spikes during commutation. Use Value: Fast avalanche response prevents MOSFET drain-source breakdown during 100 ns rise-time transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | DO-214AA package, 58 V VBR, same 600 W rating but lower RθJA (50 °C/W vs. 75 °C/W) | Better suited for surface-mount high-density layouts; requires rework of footprint and thermal relief | Select when board space is constrained and automated SMT assembly is preferred over through-hole |
| 1.5KE56CA | Same DO-15 package, 56 V VBR, but 1500 W peak power and higher IPPM (21.1 A) | Over-specified for typical 600 W use cases; larger junction capacitance may affect high-speed signal integrity | Choose only when legacy designs require backward compatibility or surge immunity beyond ISO 16750-2 Level IV |
Compared with SMBJ58CA and 1.5KE56CA, P6KE56CA-E3/54 offers optimal balance of cost, through-hole manufacturability, and thermal performance for mid-tier industrial and automotive subsystems where 600 W clamping suffices and lead-based soldering remains standard.

FAQ
What is the maximum clamping voltage of P6KE56CA-E3/54 under standard surge conditions?
The P6KE56CA-E3/54 exhibits a maximum clamping voltage (VC) of 77.0 V when subjected to its rated 7.8 A peak pulse current (IPPM) using the 10/1000 μs waveform. This value is measured per JEDEC standards and represents the upper voltage limit imposed on protected circuitry during worst-case transient events. The clamping occurs symmetrically in both directions due to its bidirectional construction.
Is P6KE56CA-E3/54 qualified for automotive applications?
P6KE56CA-E3/54 carries the E3 suffix, indicating RoHS compliance and commercial-grade qualification. For automotive use, Vishay offers the P6KE56CAHE3/54 variant with AEC-Q101 qualification. Engineers must select the HE3 version explicitly when designing for automotive environments requiring certified reliability - the E3/54 part is not AEC-Q101 qualified despite sharing identical electrical parameters.
How does the bidirectional nature of P6KE56CA-E3/54 affect PCB layout?
The bidirectional design of P6KE56CA-E3/54 eliminates polarity marking and orientation constraints - either lead can connect to the line or ground side of the protected circuit. This simplifies PCB layout, reduces assembly errors, and allows reuse in both power-rail and signal-line configurations without redesign. No silkscreen polarity indicator is required, and footprint symmetry supports automated optical inspection.
What is the thermal resistance from junction to ambient for P6KE56CA-E3/54?
The P6KE56CA-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W under standard test conditions (free-air, no heatsink). This value assumes minimal PCB copper area; actual performance improves significantly with ≥1 sq-in. of 2-oz copper connected to both leads. For thermal design, junction temperature must stay below +175 °C under worst-case power dissipation.
Can P6KE56CA-E3/54 be used in place of a unidirectional TVS like P6KE56A?
No - P6KE56CA-E3/54 is strictly bidirectional and cannot replace unidirectional P6KE56A in circuits requiring DC blocking or asymmetric clamping. Unidirectional types have a defined cathode (band-marked) and conduct only in reverse bias; substituting P6KE56CA-E3/54 would allow unintended forward conduction in DC-biased rails. Always verify circuit polarity requirements before interchange.
