Product details
Overview
P4KE13C-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal and power lines. It features a 13 V breakdown voltage (VBR min/max = 12.4 V / 13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage (VC) at 22.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P4KE13C-E3/73 datasheet, P4KE13C-E3/73 pinout, P4KE13C-E3/73 application, or P4KE13C-E3/73 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), and low leakage (<1.0 μA at VWM) under standby conditions.
Technical Context
This device operates as a voltage-clamping protection element in bidirectional configurations, responding to transient overvoltages in either polarity without requiring external polarity management. Its glass-passivated junction enables fast response time (<1.0 ns), low incremental surge resistance, and stable clamping performance across -55 °C to +175 °C junction temperature range.
The P4KE13C-E3/73 complies with AEC-Q101 for automotive-grade reliability and meets UL 94 V-0 flammability requirements via its molded epoxy DO-41 package. It delivers 400 W peak pulse power handling with 0.01% duty cycle, derated linearly above 25 °C ambient per Fig. 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines reliable conduction onset window for transient suppression |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 18.2 V at 22.0 A - clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 400 W - peak transient energy absorption capacity under standardized waveform |
| IFSM | Not applicable - bidirectional type has no forward surge rating (unidirectional only) |
| TJ max. | +175 °C - enables operation in under-hood automotive and high-temp industrial environments |
| RθJL | 66 °C/W - thermal resistance from junction to lead, critical for PCB trace heat sinking design |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads; no polarity marking for bidirectional configuration; body length ≥25.4 mm, diameter 2.0–2.7 mm.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | DO-214AA package, 600 W PPPM, lower RθJA (50 °C/W), same VBR/VC specs | Better suited for surface-mount layouts with higher power density; requires rework of footprint and thermal relief | Select when board space is constrained and higher surge margin is needed without changing clamping behavior |
| 1.5KE13CA | DO-201AD package, 1500 W PPPM, larger body, higher IPPM (103 A), same VBR/VC | Used where single-event high-energy threats dominate (e.g., utility meter front-end); less suitable for dense PCBs | Choose for legacy through-hole designs needing higher robustness margin, especially in metering or grid infrastructure |
Compared with SMBJ13CA and 1.5KE13CA, the P4KE13C-E3/73 offers optimal balance of proven automotive qualification, axial-leaded ease of manual assembly and rework, and sufficient 400 W surge capacity for most control-line protection tasks - making it preferred for cost-sensitive, medium-reliability industrial and automotive sub-systems.

FAQ
What is the polarity configuration of the P4KE13C-E3/73?
The P4KE13C-E3/73 is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive- and negative-going transients. Unlike unidirectional variants (e.g., P4KE13A), it carries no cathode band marking and has identical electrical characteristics in either direction - confirmed by the "CA" suffix and datasheet specification table.
Does the P4KE13C-E3/73 meet AEC-Q101 requirements?
Yes, the P4KE13C-E3/73 is explicitly AEC-Q101 qualified per the Vishay datasheet revision 16-Sep-2021 (Document Number: 88365). This qualification covers stress tests including HTGB, H3TRB, TC, AC/DC, and ESD - validating its suitability for automotive electronic control units and sensor modules.
What is the maximum clamping voltage of the P4KE13C-E3/73 under surge conditions?
The P4KE13C-E3/73 exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 22.0 A using the standard 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events.
Can the P4KE13C-E3/73 be used in place of a unidirectional P4KE13A?
No - the P4KE13C-E3/73 and P4KE13A are not functionally interchangeable due to fundamental polarity differences. The P4KE13A is unidirectional (cathode-marked, conducts only in reverse), while the P4KE13C-E3/73 is bidirectional (no marking, symmetric conduction). Substitution requires circuit review to ensure correct biasing and protection directionality.
What is the thermal resistance from junction to lead for the P4KE13C-E3/73?
The P4KE13C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, as specified in the Thermal Characteristics section of the Vishay datasheet. This parameter governs heat transfer efficiency to the PCB leads and directly impacts safe steady-state power dissipation (PD = 1.5 W at TL = 75 °C).
