Product details

Overview

P4KE24C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 24 V breakdown voltage (V_BR min/max = 22.8 V / 25.2 V), 400 W peak pulse power (10/1000 μs), and clamps to ≤33.2 V at 12 A peak pulse current - used in automotive sensor line protection and industrial I/O interface surge suppression.

For engineers reviewing the P4KE24C-E3/54 datasheet, P4KE24C-E3/54 pinout, P4KE24C-E3/54 application, or P4KE24C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (R_θJL = 66 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 transient immunity requirements.

Technical Context

This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both polarities, enabling robust ESD and surge suppression without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at 20.5 V stand-off), while the 10/1000 μs waveform rating reflects real-world lightning-induced surges per IEC 61000-4-5.

The P4KE24C-E3/54 exhibits a temperature coefficient of +0.094 %/°C for V_BR, indicating predictable voltage drift over temperature, and supports operation from −55 °C to +175 °C junction temperature - critical for under-hood automotive and industrial environments where thermal stability is mandatory.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR (min/max)	22.8 V / 25.2 V at 1.0 mA - defines reliable conduction onset range for bidirectional clamping
V_WM	20.5 V - maximum continuous reverse working voltage before leakage exceeds 1 μA
V_C @ I_PPM	≤33.2 V at 12.0 A - clamped voltage during 400 W transient, limiting stress on downstream ICs
P_PPM	400 W (10/1000 μs) - peak surge energy handling capacity compliant with IEC 61000-4-5 Level 3

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ24CA	DO-214AA package (SMB), 600 W P_PPM, V_C = 38.9 V @ 15.4 A, R_θJA = 40 °C/W	Higher power rating but larger footprint; better thermal dissipation on board	Select SMBJ24CA when higher surge margin or lower clamping voltage drift with PCB copper area is required.
1.5KE24CA	DO-201AD package, 1500 W P_PPM, V_C = 38.7 V @ 38.8 A, T_J max = 175 °C, no AEC-Q101	Higher energy handling but non-automotive qualified; larger axial package	Choose 1.5KE24CA for industrial mains-side protection where AEC-Q101 is not mandated and space allows.

Compared with SMBJ24CA and 1.5KE24CA, the P4KE24C-E3/54 offers tighter V_BR tolerance (±5 % vs ±10 %), AEC-Q101 qualification, and DO-41 compatibility with legacy through-hole designs - making it optimal for cost-sensitive, space-constrained automotive and industrial replacements where 400 W surge immunity suffices.

FAQ

What does the "C" suffix in P4KE24C-E3/54 indicate?

The "C" suffix denotes bidirectional configuration - meaning the P4KE24C-E3/54 conducts and clamps symmetrically in both polarities, unlike unidirectional variants (e.g., P4KE24A-E3/54) that have a cathode band. This makes P4KE24C-E3/54 ideal for AC-coupled or polarity-agnostic signal lines such as CAN bus or RS-485, where transient direction cannot be predicted.

Is P4KE24C-E3/54 AEC-Q101 qualified?

Yes, P4KE24C-E3/54 is AEC-Q101 qualified - confirmed in Vishay's official documentation (Document Number 88365, Revision 16-Sep-2021). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, validating its suitability for automotive under-hood and chassis applications where reliability is mission-critical.

What is the clamping voltage of P4KE24C-E3/54 at its rated peak pulse current?

The P4KE24C-E3/54 clamps to a maximum of 33.2 V at its rated peak pulse current of 12.0 A (10/1000 μs waveform). This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 3.3 V or 5 V logic interfaces downstream.

Can P4KE24C-E3/54 replace P4KE24A-E3/54 in a design?

No - P4KE24C-E3/54 is bidirectional while P4KE24A-E3/54 is unidirectional, so direct replacement requires circuit review. The unidirectional version has a cathode band and conducts only in reverse bias; substituting P4KE24C-E3/54 may cause unintended conduction in DC-biased lines. Use P4KE24C-E3/54 only where symmetrical clamping is explicitly required.

What is the standoff voltage (V_WM) of P4KE24C-E3/54 and why does it matter?

The standoff voltage V_WM of P4KE24C-E3/54 is 20.5 V - the maximum continuous DC or RMS voltage the device blocks without exceeding 1 μA leakage. This parameter ensures the P4KE24C-E3/54 remains non-conductive during normal operation (e.g., on a 24 V industrial bus), avoiding power loss or false triggering while still responding instantly to transients exceeding 22.8 V.
