Product details
Overview
P4KE13-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on DC power rails and signal lines. It features 13 V nominal breakdown voltage (VBR = 12.4–13.7 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 ICs in industrial power supplies.
For engineers reviewing the P4KE13-E3/73 datasheet, P4KE13-E3/73 pinout, P4KE13-E3/73 application, or P4KE13-E3/73 equivalent, key selection considerations include its unidirectional polarity, DO-41 leaded package compatibility with through-hole PCB assembly, 1.5 W steady-state power dissipation, and AEC-Q101 qualification for automotive-grade reliability where surge immunity is critical.
Technical Context
This TVS diode operates as a voltage-clamping protection device that remains high-impedance below VWM (11.1 V) and rapidly avalanches above VBR (min. 12.4 V) to limit transient overvoltage. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance for consistent clamping performance across repetitive surges.
The device supports bidirectional variants via "CA" suffix but P4KE13-E3/73 is strictly unidirectional, with cathode marked by color band. It complies with JESD 22-B106 (275 °C solder dip, 10 s) and JESD 201 Class 1A whisker testing, and is rated for operation from –55 °C to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche onset range for reliable clamping threshold |
| 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 stress on downstream components |
| PPPM | 400 W - peak transient power handling capability under standardized surge waveform |
| IFSM | 40 A - non-repetitive forward surge current rating (8.3 ms half-sine), relevant for input rectifier protection |
| TJ max. | +175 °C - enables use in high-temperature environments such as engine control units or enclosed power converters |
| Package | DO-41 (DO-204AL) - axial-leaded, through-hole package with UL 94 V-0 molded epoxy body |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, glass-passivated silicon junction in molded epoxy case; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode | Avalanche clamping terminal | Marked with color band; connected to protected line (e.g., +12 V rail) to clamp positive transients to VC |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable leakage current (<1.0 μA) and long-term reliability under thermal cycling |
| 400 W peak pulse power (10/1000 μs) | Provides robust protection against common ESD and inductive switching transients in industrial systems |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including body electronics and powertrain subsystems |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage margin between breakdown and clamping, improving system-level surge margin |
| UL 94 V-0 flammability rating | Molding compound meets stringent fire safety requirements for enclosed power equipment |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input Stage |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Surface-mount SMB package (vs. through-hole DO-41); same VBR range (12.4–13.7 V), identical 400 W rating | Requires rework of PCB layout; better suited for automated SMT production and space-constrained designs | Select SMBJ13A when migrating to surface-mount assembly or reducing board footprint is prioritized over manual repairability. |
| 1.5KE13A | Higher peak pulse power (1500 W vs. 400 W); same DO-41 package and VBR (12.4–13.7 V); larger junction area | Used where higher-energy transients (e.g., AC mains coupling) exceed P4KE13-E3/73's 400 W limit | Choose 1.5KE13A only if surge threat level requires >400 W capability - otherwise P4KE13-E3/73 offers tighter VC and lower cost. |
Compared with SMBJ13A and 1.5KE13A, P4KE13-E3/73 delivers optimal balance of cost, through-hole serviceability, and precision clamping (18.2 V) for mid-energy transients in automotive and industrial DC systems - without over-specifying power or sacrificing manufacturability.

FAQ
What is the polarity configuration of P4KE13-E3/73?
P4KE13-E3/73 is a unidirectional TVS diode, meaning it conducts only in reverse-bias avalanche mode. The cathode is marked by a color band on the DO-41 body, and it must be oriented with cathode toward the protected line (e.g., +12 V) and anode to ground. Bidirectional variants use the "CA" suffix (e.g., P4KE13CA), which P4KE13-E3/73 does not have.
Does P4KE13-E3/73 meet automotive qualification standards?
Yes, P4KE13-E3/73 carries the E3 suffix, indicating RoHS compliance and AEC-Q101 qualification per Vishay documentation. This certification validates its suitability for automotive applications including engine control, body electronics, and infotainment systems where reliability under thermal cycling and mechanical shock is required.
What is the maximum clamping voltage of P4KE13-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P4KE13-E3/73 is 18.2 V at 22.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Can P4KE13-E3/73 be used in AC line protection?
No, P4KE13-E3/73 is not suitable for AC line protection due to its unidirectional structure and 11.1 V stand-off voltage (VWM). It is designed for DC or single-polarity signal line protection. For AC applications, bidirectional variants like P4KE13CA or higher-voltage TVS arrays with symmetrical clamping are required.
What is the thermal resistance of P4KE13-E3/73 from junction to lead?
The typical thermal resistance from junction to lead (RθJL) for P4KE13-E3/73 is 66 °C/W, as specified in the Vishay datasheet. This parameter is essential for estimating junction temperature rise under steady-state power dissipation (PD = 1.5 W) and informs heatsinking decisions in high-duty-cycle surge environments.
