Product details

Overview

P4KE13A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level overvoltage protection. It features a 12.4 V minimum breakdown voltage (V_BR), 11.1 V standoff voltage (V_WM), 18.2 V clamping voltage (V_C) at 22.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform-used to safeguard MOSFETs, ICs, and sensor signal lines against inductive switching transients.

For engineers reviewing the P4KE13A-E3/54 datasheet, P4KE13A-E3/54 pinout, P4KE13A-E3/54 application, or P4KE13A-E3/54 equivalent, key selection criteria include unidirectional polarity, DO-41 mechanical compatibility, 1.0 mA test current specification, 1.0 μA max reverse leakage at V_WM, and AEC-Q101 qualification status for automotive-grade reliability validation.

Technical Context

This TVS diode operates as a clamping device that remains non-conductive below its 11.1 V standoff voltage and rapidly transitions to low-impedance conduction above its 12.4–13.7 V breakdown range. Its glass-passivated junction enables fast response time (<1 ns) and stable surge handling under repetitive 0.01% duty cycle conditions.

The device complies with IEC 61000-4-2/4-4/4-5 ESD and surge immunity standards when integrated into PCB-level protection networks. Thermal resistance is characterized at R_θJL = 66 °C/W (junction-to-lead) and R_θJA = 100 °C/W (junction-to-ambient with 10 mm lead length), supporting thermal design in constrained layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR min/max	12.4 V / 13.7 V at 1.0 mA test current - defines precise voltage threshold for avalanche conduction onset
V_WM	11.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA
V_C at I_PPM	18.2 V at 22.0 A - clamped voltage during 10/1000 μs transient, limiting stress on downstream components
P_PPM	400 W - peak pulse power dissipation capability with standardized waveform, enabling robust surge margin
I_FSM	40 A - single half-sine surge current rating (8.3 ms), supporting inductive load switch-off events
T_J max	+175 °C - maximum junction temperature, allowing operation in under-hood automotive environments
Package	DO-41 (DO-204AL) - industry-standard axial-leaded package with UL 94 V-0 molded epoxy body

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	Surface-mount SMB package; same V_BR range (12.4–13.7 V); 600 W P_PPM; lower V_C (21.5 V @ 19.9 A)	Requires PCB re-layout; better suited for high-density consumer boards where DO-41 axial leads are impractical	Select SMBJ13A when automated SMT assembly and space constraints outweigh through-hole serviceability needs.
P6KE13A	Same DO-41 package; 600 W P_PPM; higher I_PPM (33.3 A); identical V_BR/V_WM/V_C specs	Higher surge margin for industrial motor drive I/O protection where 400 W is insufficient	Choose P6KE13A when legacy DO-41 footprint must be retained but 50% higher pulse power is required for EN 61000-4-5 compliance.

Compared with P4KE13A-E3/54, SMBJ13A offers superior power density and SMT compatibility but lacks AEC-Q101 qualification, while P6KE13A delivers higher surge capacity in the same axial package-making it suitable for harsher industrial transients without layout change.

FAQ

What is the polarity configuration of the P4KE13A-E3/54?

The P4KE13A-E3/54 is a unidirectional TVS diode, with the cathode identified by a color band on the DO-41 package body. It conducts in forward bias and clamps reverse transients above its breakdown voltage. Bidirectional variants use the "CA" suffix (e.g., P4KE13CA), which P4KE13A-E3/54 does not have.

Does the P4KE13A-E3/54 meet automotive reliability standards?

Yes, the P4KE13A-E3/54 carries the E3 suffix, indicating RoHS-compliance and AEC-Q101 qualification per Vishay documentation. This validates its suitability for automotive applications including engine control units, body electronics, and ADAS sensor modules where temperature cycling and long-term surge endurance are critical.

What is the maximum clamping voltage of the P4KE13A-E3/54 under surge conditions?

The P4KE13A-E3/54 has a maximum clamping voltage (V_C) of 18.2 V at 22.0 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuits during transient events.

Can the P4KE13A-E3/54 be used in bidirectional signal line protection?

No, the P4KE13A-E3/54 is unidirectional and unsuitable for bidirectional AC or differential signal lines without external circuitry. For such applications, Vishay specifies bidirectional variants like P4KE13CA, which provide symmetrical clamping in both directions and lack polarity marking.

What is the thermal resistance profile of the P4KE13A-E3/54?

The P4KE13A-E3/54 has a typical junction-to-lead thermal resistance (R_θJL) of 66 °C/W and junction-to-ambient resistance (R_θJA) of 100 °C/W with 10 mm lead length. These values inform heatsinking requirements and derating curves for sustained power dissipation beyond transient events.
