Product details
Overview
P6KE75C-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 surges, and inductive switching transients. It features a 75 V breakdown voltage (VBR min/max = 71.3–78.8 V), 600 W peak pulse power rating (10/1000 µs), clamping voltage of 103 V at 5.8 A peak pulse current, and operates across –55 °C to +175 °C junction temperature range. It is commonly deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6KE75C-E3/73 datasheet, P6KE75C-E3/73 pinout, P6KE75C-E3/73 application, or P6KE75C-E3/73 equivalent, key selection criteria include its bi-directional polarity, DO-204AC (DO-15) package compatibility, UL 94 V-0 rated epoxy molding, AEC-Q101 qualification status, and verified clamping performance under repetitive 10/1000 µs surge conditions.
Technical Context
The P6KE75C-E3/73 implements an avalanche breakdown mechanism in a glass-passivated silicon junction, enabling sub-nanosecond response to transient overvoltages. Its bi-directional configuration allows symmetric clamping in AC-coupled or floating signal paths without polarity constraints.
It delivers 600 W peak pulse power handling with a 10/1000 µs waveform at 0.01 % duty cycle, supported by low incremental surge resistance and thermal resistance of 20 °C/W (junction-to-lead). The device maintains stable VBR with a temperature coefficient of 0.105 %/°C and exhibits ≤1.0 µA reverse leakage at 64.1 V stand-off voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V - Ensures reliable avalanche conduction onset within tight tolerance at 1.0 mA test current |
| VWM | 64.1 V - Maximum continuous working voltage before significant leakage; defines safe operating margin below VBR |
| VC @ IPPM | 103 V at 5.8 A - Clamped voltage during worst-case 10/1000 µs surge; determines protected circuit's maximum stress level |
| PPPM | 600 W - Peak transient energy absorption capability; enables robust protection against IEC 61000-4-5 Level 4 surges |
| ID @ VWM | ≤1.0 µA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes |
| TJ max | +175 °C - Supports operation in under-hood automotive and high-temperature industrial environments |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs in engine control units from load dump and jump-start transients. IC Role / Device Role / Timing Role: Bi-directional TVS clamp absorbing up to 600 W surge energy while limiting rail voltage to ≤103 V.

Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops) of pressure sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: Fast-response (<1 ns) voltage clamp placed directly at connector interface to shunt transients before reaching op-amp input stage. Use Value: Maintains signal fidelity with <1 µA leakage at 64.1 V, avoiding offset errors in precision current-sense circuits. |
| Telecom Line Interface Protection | Consumer Appliance Motor Drive Protection |
|
Use Scenario: Safeguarding RS-485 transceiver I/O pins in base station backhaul modules exposed to lightning-induced surges on long cable runs.

Use Scenario: Suppressing inductive kickback from brushed DC motor commutation in smart home appliances (e.g., washing machine drum drives). IC Role / Device Role / Timing Role: Primary surge absorber across motor terminals, diverting energy away from H-bridge MOSFETs and gate drivers. Use Value: Withstands 100 A non-repetitive forward surge (IFSM), preventing catastrophic failure during stall or jam conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | Same 75 V bi-directional breakdown, but SMC (DO-214AB) surface-mount package; 600 W rating; lower RθJA (50 °C/W vs. 75 °C/W) | Requires re-layout for SMT assembly; better suited for space-constrained, high-density boards | Select SMBJ75CA when migrating to automated SMT production or improving thermal performance in compact enclosures |
| 1.5KE75CA | Same DO-204AC package and 75 V rating, but higher 1500 W peak power; larger die size; higher clamping voltage (121 V) | Overqualified for 600 W use cases; may cause excessive voltage overshoot in low-voltage logic protection | Choose 1.5KE75CA only when system-level testing confirms need for >1 kV surge margin beyond IEC 61000-4-5 requirements |
Compared with SMBJ75CA and 1.5KE75CA, the P6KE75C-E3/73 offers optimal balance of proven DO-204AC through-hole compatibility, AEC-Q101 qualification, and precise 103 V clamping-making it ideal for cost-sensitive, high-reliability automotive and industrial replacements where board real estate and thermal mass are not limiting factors.

FAQ
What does the "C" suffix indicate in P6KE75C-E3/73?
The "C" in P6KE75C-E3/73 denotes bi-directional polarity, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike uni-directional variants (e.g., P6KE75A), the P6KE75C-E3/73 has no cathode marking and functions identically regardless of terminal orientation-critical for AC-coupled or floating signal paths where polarity is undefined. This is confirmed in Vishay's datasheet section "Devices for Bi-Direction Applications".
Is P6KE75C-E3/73 RoHS compliant and halogen-free?
Yes, P6KE75C-E3/73 carries the "E3" suffix, which Vishay specifies as RoHS-compliant per Directive 2011/65/EU and compliant with JEDEC JS709A halogen-free standards. The device uses matte tin-plated leads and UL 94 V-0 rated epoxy molding compound-both documented in the "Mechanical Data" and "Material Categorization" sections of the official datasheet (Document Number: 88369).
What is the maximum clamping voltage of P6KE75C-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE75C-E3/73 is 103 V, measured at its rated peak pulse current (IPPM) of 5.8 A using the standardized 10/1000 µs waveform. This value is specified in the "Electrical Characteristics" table for P6KE75A/C variants and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can P6KE75C-E3/73 replace P6KE75A in a design?
No-P6KE75C-E3/73 and P6KE75A are not interchangeable without circuit review. P6KE75A is uni-directional (cathode-banded), while P6KE75C-E3/73 is bi-directional (no band). Substituting one for the other may result in unintended conduction or failed protection in DC-biased applications. The P6KE75C-E3/73 datasheet explicitly states polarity differences in the "Notes" section and "Polarity" row of the "Primary Characteristics" table.
What is the thermal resistance specification for P6KE75C-E3/73?
P6KE75C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W, as published in the "Thermal Characteristics" table of the Vishay datasheet. These values assume standard lead length (0.375") and define power derating behavior above 25 °C ambient-critical for sustained surge duty cycles or high-temperature mounting locations.
