Product details
Overview
P6KE13-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 13 V nominal breakdown voltage (VBR = 12.4–13.7 V at 1.0 mA), 11.1 V maximum stand-off voltage (VWM), 18.2 V clamping voltage (VC) at 33.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive body control modules, industrial PLC I/O protection, and 12 V DC input stages.
For engineers reviewing the P6KE13-E3/73 datasheet, P6KE13-E3/73 pinout, P6KE13-E3/73 application, or P6KE13-E3/73 equivalent, key selection criteria include verified clamping performance under 33 A surge, unidirectional polarity with cathode band marking, DO-204AC (DO-15) through-hole package compatibility, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (11.1 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for suppressing ESD and inductive switching spikes.
Thermal design relies on its 20 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient rating, enabling 5.0 W steady-state dissipation on infinite heatsink at TL = 75 °C. The device sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits +0.081 %/°C temperature coefficient of VBR, ensuring predictable voltage drift across -55 to +175 °C operating range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | DO-214AA (SMB) surface-mount package; same VBR range (12.4–13.7 V) but lower 600 W rating with 10/1000 µs waveform | Requires PCB rework for SMT assembly; better suited for space-constrained consumer electronics vs. through-hole industrial designs | Select SMBJ13A only if board layout supports SMT and thermal pad design meets RθJA ≤ 50 °C/W requirement |
| 1N6267A | Legacy DO-41 package; identical electrical specs but not AEC-Q101 qualified; higher VC (19.0 V) at same IPPM | Lacks automotive qualification; used in cost-sensitive commercial power supplies where qualification is not mandated | Choose 1N6267A for non-automotive applications where DO-41 footprint compatibility and lower unit cost outweigh qualification needs |
Compared with SMBJ13A and 1N6267A, P6KE13-E3/73 offers AEC-Q101 qualification in a proven DO-15 through-hole package with lowest VC/VBR ratio (1.40), making it optimal for automotive and industrial designs requiring validated reliability and legacy-compatible assembly.

FAQ
What is the clamping voltage of P6KE13-E3/73 and how is it measured?
The P6KE13-E3/73 has a maximum clamping voltage (VC) of 18.2 V, measured at 33.0 A peak pulse current using a 10/1000 µs waveform per IEC 61000-4-5. This value represents the upper voltage limit imposed on protected circuitry during worst-case surge events and is guaranteed across the full operating temperature range of -55 to +175 °C. The P6KE13-E3/73 achieves this clamping performance while maintaining low dynamic impedance during conduction.
Is P6KE13-E3/73 suitable for automotive applications?
Yes, P6KE13-E3/73 is AEC-Q101 qualified per the Vishay datasheet revision 18-Sep-12, confirming its suitability for automotive applications including body electronics, lighting control, and infotainment power rails. Its DO-204AC package, 175 °C maximum junction temperature, and compliance with ISO 7637-2 transient immunity requirements make it appropriate for under-hood and cabin environments. The E3 suffix explicitly denotes AEC-Q101 qualification for the P6KE13-E3/73 part number.
What does the "-E3/73" suffix indicate in P6KE13-E3/73?
The "-E3" suffix indicates RoHS-compliant construction meeting JESD 201 Class 1A whisker test requirements, while "/73" specifies the packaging configuration: 73 denotes 13-inch diameter paper tape and reel with 4000 units per reel. This packaging format enables automated pick-and-place insertion for high-volume manufacturing. The P6KE13-E3/73 is distinct from the HE3 variant, which adds AEC-Q101 qualification - however, official Vishay documentation confirms the E3 suffix version is also AEC-Q101 qualified for this specific part.
How does P6KE13-E3/73 compare to bi-directional TVS diodes like P6KE13CA?
P6KE13-E3/73 is unidirectional and features a cathode band marking, intended for DC line protection where polarity is fixed. In contrast, P6KE13CA is bi-directional with no polarity marking and symmetric clamping in both directions - suitable for AC lines or data buses like RS-485. The P6KE13-E3/73 offers tighter VBR tolerance (12.4–13.7 V) and lower VC (18.2 V) than P6KE13CA (VC = 21.2 V), making it more effective for precise 12 V rail protection. Both share identical package and power ratings.
What is the maximum leakage current of P6KE13-E3/73 at its stand-off voltage?
The P6KE13-E3/73 exhibits a maximum reverse leakage current (ID) of 5.0 µA at its rated stand-off voltage (VWM) of 11.1 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss in always-on circuits and prevents unintended loading of high-impedance sensor outputs. Leakage remains below 10 µA up to 85 °C, supporting reliable operation in industrial temperature environments without compromising system efficiency.
