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.

Pin/Terminal Circuit Role Design Meaning
Anode/Cathode (symmetrical) Bidirectional transient conduction path No functional distinction - terminals interchangeable; clamps positive or negative transients equally
Lead 1 / Lead 2 Thermal and electrical interface to PCB Leads serve as primary heat dissipation path (RθJL = 66 °C/W); require ≥10 mm length for rated PD = 1.5 W

Key Features

Feature Design Value
AEC-Q101 qualified Validated for automotive electronics use including engine control, body modules, and ADAS sensor protection
Glass passivated junction Ensures stable VBR tolerance and low leakage (<1.0 μA) over lifetime and temperature cycling
400 W peak pulse power (10/1000 μs) Withstands repetitive ESD and load-dump surges common in 12 V vehicle electrical systems
UL 94 V-0 compliant molding Self-extinguishing epoxy housing prevents flame propagation in enclosed enclosures
Matte tin plating, J-STD-002 compliant Guarantees reliable solder wetting and intermetallic formation on standard PCB finishes

Applications

IC Role / Device Role: Primary overvoltage clamp on input terminal before optocoupler or Schmitt trigger.

Use Value: Maintains <1.0 μA leakage at 24 V nominal, ensuring clean logic threshold detection while absorbing 400 W transients.

Consumer Appliance Motor Drive Board Telecom Power Supply Surge Protection

Use Scenario: Shielding MCU reset and communication lines from commutation noise generated by brushed DC motors in washing machines.

IC Role / Device Role: Localized TVS at motor driver IC supply pins and feedback signal paths.

Use Value: Fast <1 ns response captures high-frequency ringing before it couples into sensitive analog or timing circuits.

Use Scenario: Secondary-level surge suppression on 48 V telecom power rails subjected to lightning-induced surges per IEC 61000-4-5.

IC Role / Device Role: Coordination partner with upstream MOVs and GDTs in multi-stage protection architecture.

Use Value: Precise 11.1 V VWM allows tight coordination margin with 12 V LDO regulators downstream.

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).
