Product details

Overview

P4KE27C-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 27 V breakdown voltage (V_BR min/max = 25.7 V / 28.4 V), 23.1 V stand-off voltage (V_WM), 37.5 V maximum clamping voltage (V_C) at 10.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.

For engineers reviewing the P4KE27C-E3/54 datasheet, P4KE27C-E3/54 pinout, P4KE27C-E3/54 application, or P4KE27C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 through-hole compatibility, AEC-Q101 qualification status, and transient suppression performance in automotive sensor interfaces and industrial I/O protection circuits.

Technical Context

This device operates as a voltage-clamping protector with symmetrical avalanche breakdown in both polarities, enabling robust surge immunity without polarity sensitivity. Its glass-passivated junction ensures stable V_BR tolerance (±5%) and low incremental surge resistance, critical for consistent clamping under repetitive transients.

The P4KE27C-E3/54 delivers 37.5 V clamping at 10.7 A IPPM with 10/1000 μs waveform, and maintains operation across -55 °C to +175 °C junction temperature range. Thermal resistance is 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient), supporting reliable power dissipation in constrained PCB layouts.

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	Surface-mount SMB package; 24 V V_WM, 38.9 V V_C @ 10.3 A; 600 W P_PPM	Requires PCB redesign for SMT placement; better suited for high-density consumer electronics	Select when board space is constrained and automated assembly is required
1.5KE27C	Same DO-41 package; higher 1500 W P_PPM; 27 V V_BR; larger 1.5 kW rating increases thermal mass	Higher energy handling supports longer-duration transients (e.g., AC line surges), but larger footprint	Select when legacy DO-41 layout must be retained and surge energy exceeds 400 W

Compared with P4KE27C-E3/54, SMBJ24CA offers higher power density in SMT format but lacks AEC-Q101 qualification, while 1.5KE27C provides greater surge energy margin in identical through-hole form factor-making P4KE27C-E3/54 optimal for cost-sensitive, AEC-Q101-compliant 24 V automotive and industrial protection.

FAQ

What is the breakdown voltage range for P4KE27C-E3/54?

The P4KE27C-E3/54 has a guaranteed breakdown voltage (V_BR) range of 25.7 V to 28.4 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This ±5% tolerance ensures predictable clamping behavior in bidirectional configurations and supports reliable coordination with downstream 24 V system components. The value is confirmed in Vishay's official datasheet revision 16-Sep-2021, Document Number 88365.

Is P4KE27C-E3/54 suitable for automotive applications?

Yes, P4KE27C-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay's documentation. Its operating junction temperature range of -55 °C to +175 °C, glass-passivated junction stability, and compliance with surge immunity standards (e.g., ISO 7637-2) make it appropriate for engine control units, body electronics, and sensor interfaces. The "HE3" variant is fully qualified; the "E3" suffix indicates commercial grade with identical electrical specs but not AEC-Q101 certification.

What does the "C" suffix indicate in P4KE27C-E3/54?

The "C" in P4KE27C-E3/54 denotes bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., P4KE27A), it has no cathode marking and functions identically regardless of terminal orientation. This enables simplified layout in AC-coupled or polarity-agnostic signal paths such as telecom lines or differential bus interfaces.

What is the maximum clamping voltage of P4KE27C-E3/54 under surge conditions?

The P4KE27C-E3/54 clamps to a maximum of 37.5 V at its rated peak pulse current of 10.7 A, using the standardized 10/1000 μs double-exponential waveform. This clamping level is verified under worst-case conditions (T_A = 25 °C) and remains effective across its full operating temperature range. The low V_C ensures compatibility with 24 V systems where sustained overvoltage above 40 V risks damaging downstream ICs.

How is P4KE27C-E3/54 packaged and delivered?

P4KE27C-E3/54 is supplied in DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads, conforming to J-STD-002 solderability requirements. It ships in 13-inch paper tape and reel format with 5500 units per reel (ordering code /54). The "E3" suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, making it suitable for lead-free reflow and wave soldering processes.
