Product details
Overview
P6KE56C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for overvoltage protection of sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. It features a 56 V breakdown voltage (VBR min = 53.2 V, max = 58.8 V), 77.0 V maximum clamping voltage at 7.8 A peak pulse current (10/1000 µs), 600 W peak pulse power rating, and DO-204AC (DO-15) package. It is used in automotive sensor signal lines, industrial I/O ports, and telecom interface protection.
For engineers reviewing the P6KE56C-E3/73 datasheet, P6KE56C-E3/73 pinout, P6KE56C-E3/73 application, or P6KE56C-E3/73 equivalent, key selection criteria include bi-directional clamping capability, low thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and compliance with UL 497B for surge protectors - all confirmed for this specific variant.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM = 47.8 V), then rapidly avalanches into low-impedance conduction when transient voltage exceeds VBR. Its bi-directional symmetry ensures identical clamping behavior in both polarities, eliminating polarity sensitivity in AC-coupled or floating signal paths.
It delivers 600 W peak pulse power handling per the standardized 10/1000 µs waveform, with thermal derating above 25 °C ambient (derates to zero at TL = 175 °C). The glass-passivated junction enables fast response (<1 ns), while the DO-204AC package supports manual or automated through-hole assembly with matte tin-plated leads compliant to J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 53.2 V / 58.8 V at IT = 1.0 mA - defines precise avalanche onset threshold for reliable clamping initiation |
| VWM | 47.8 V - maximum continuous reverse working voltage; ensures no leakage conduction during normal operation |
| VC @ IPPM | 77.0 V at 7.8 A (10/1000 µs) - actual worst-case voltage seen by protected circuit during surge event |
| PPPM | 600 W - peak transient energy absorption capacity without failure under standardized surge test condition |
| IPPM | 7.8 A - maximum non-repetitive surge current the device safely clamps without degradation |
| TJ max | +175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports effective heat dissipation into PCB copper |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating; matte tin-plated leads, RoHS-compliant (E3 suffix), AEC-Q101 qualified (HE3 variant exists but P6KE56C-E3/73 is commercial-grade E3).
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Automotive Sensor Signal Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed directly at connector entry point to clamp surges before reaching IC pins. Use Value: Limits transient voltage to ≤77.0 V, preventing latch-up or gate oxide damage in 5 V/12 V interface ICs while maintaining signal integrity below 47.8 V operating range. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in programmable logic controllers against field wiring surges and ground bounce. IC Role / Device Role / Timing Role: Primary front-end protection element mounted on input terminal block or PCB edge connector. Use Value: Withstands 600 W surges without degradation, ensuring system uptime in factory-floor environments where cable routing induces repetitive transients. |
| Telecom Line Interface Protection | Consumer USB/AV Port Surge Guard |
Use Scenario: Shielding Ethernet PHY magnetics, DSL line drivers, and telephone line interface ICs from lightning-induced longitudinal surges. IC Role / Device Role / Timing Role: Bi-directional TVS connected across differential pairs (e.g., tip/ring) to suppress common-mode transients. Use Value: Symmetrical clamping ensures balanced suppression on both conductors, preserving signal skew and minimizing EMI radiation during clamping events. |
Use Scenario: Adding secondary-level surge immunity to USB 2.0 data lines, HDMI hot-plug detection circuits, and audio jack inserts in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF typical at 0 V) shunt protector placed immediately after ESD filter ferrites. Use Value: Clamps transients to 77.0 V within <1 ns while adding negligible signal distortion - critical for high-speed digital interfaces up to 480 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | Same bi-directional function, higher VBR (58–64.4 V), lower VC (93.6 V @ 6.4 A), SMB package (surface-mount) | Requires PCB rework for SMT layout; better suited for space-constrained designs with automated assembly | Select when board real estate is limited and SMT process is established; verify thermal pad design for 600 W pulse handling |
| 1.5KE56C | Same VBR/VC specs, identical DO-204AC package, but rated for 1500 W peak power (10/1000 µs) | Over-specified for most 600 W applications; higher cost and larger physical footprint than needed | Choose only if legacy design requires backward compatibility or future-proofing against higher-energy threat models |
Compared with P6KE56C-E3/73, SMBJ58CA offers surface-mount convenience at the expense of through-hole mechanical robustness and higher clamping voltage, while 1.5KE56C provides excess surge margin in the same package but with unnecessary cost and size overhead for standard 600 W requirements.

FAQ
What does the "C" suffix in P6KE56C-E3/73 indicate?
The "C" suffix denotes bi-directional functionality: P6KE56C-E3/73 provides symmetrical clamping in both forward and reverse directions, making it suitable for AC-coupled signals, differential lines, and floating-ground applications. Unlike uni-directional variants (e.g., P6KE56A), it has no cathode marking and behaves identically regardless of polarity - a key distinction confirmed in Vishay's datasheet section "Devices for Bi-Direction Applications".
Is P6KE56C-E3/73 AEC-Q101 qualified?
No, P6KE56C-E3/73 is the commercial-grade E3 variant and is not AEC-Q101 qualified. Vishay offers the HE3 suffix (e.g., P6KE56C-HE3/73) for AEC-Q101 qualification. The datasheet explicitly states "Base P/N-E3 – RoHS compliant, commercial grade" and "Base P/NHE3 – RoHS compliant, AEC-Q101 qualified", confirming P6KE56C-E3/73 meets commercial reliability standards but not automotive stress-test requirements.
What is the maximum clamping voltage of P6KE56C-E3/73 and under what test condition?
The maximum clamping voltage of P6KE56C-E3/73 is 77.0 V, measured at a peak pulse current (IPPM) of 7.8 A using the standardized 10/1000 µs double-exponential waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table of the Vishay datasheet (Document Number: 88369) and represents the worst-case voltage imposed on the protected circuit during a full-rated surge event.
Can P6KE56C-E3/73 be used in place of a uni-directional TVS like P6KE56A?
P6KE56C-E3/73 can replace P6KE56A in most applications, but only if polarity insensitivity is acceptable and the circuit does not rely on DC blocking in one direction. Since P6KE56C-E3/73 conducts in both directions above VBR, it must not be used where reverse-biased DC blocking is required - e.g., in DC power rail protection with single-polarity biasing. Always verify signal path topology before substitution.
What is the thermal resistance specification for P6KE56C-E3/73 and why does it matter?
P6KE56C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, per Vishay's "THERMAL CHARACTERISTICS" table. This low value enables efficient heat transfer from the silicon junction to the PCB copper via the leads during surge events, preventing thermal runaway. It directly impacts safe repetition rate and sustained power handling - critical for applications with frequent transient exposure such as industrial motor controls.
