Product details

Overview

P4KE180-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 154 V standoff voltage (VWM), 171–189 V breakdown range (VBR) at 1 mA, 246 V maximum clamping voltage at 1.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.

For engineers reviewing the P4KE180-E3/54 datasheet, P4KE180-E3/54 pinout, P4KE180-E3/54 application, or P4KE180-E3/54 equivalent, key selection criteria include clamping voltage margin versus protected IC V_DD, I_PPM capability under system-level surge stress (e.g., ISO 7637-2 Pulse 1/2a), thermal derating above 25 °C, and AEC-Q101 qualification status for automotive use cases.

Technical Context

This device operates as a silicon avalanche diode, leveraging glass-passivated junction technology to achieve fast response (<1 ns) and low dynamic impedance during transient events. Its unidirectional polarity-marked with cathode band-enables integration into DC-biased rails where reverse conduction must be blocked until clamping threshold is exceeded.

The P4KE180-E3/54 is rated for 175 °C maximum junction temperature and exhibits 0.108 %/°C temperature coefficient of V_BR, ensuring predictable voltage drift across automotive and industrial operating ranges. Thermal resistance from junction to lead is 66 °C/W, supporting reliable power dissipation when mounted with adequate PCB copper area.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	154 V - Maximum continuous reverse working voltage before leakage exceeds 1 μA; defines safe operating ceiling for DC bias applications.
V_BR min/max	171 V / 189 V at 1 mA - Confirmed breakdown range ensures robust overvoltage triggering without premature conduction.
V_C @ I_PPM	246 V at 1.6 A - Clamping voltage limits downstream component stress during 10/1000 μs surge; <9% overshoot vs. V_BR.
P_PPM	400 W - Peak pulse power handling per single transient event; validated per IEC 61000-4-5 Level 4 compliance testing.
I_FSM	40 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports inrush current immunity in power supply inputs.
T_J max	175 °C - Enables operation in under-hood automotive environments and high-ambient industrial enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ180A	DO-214AA package; 180 V V_BR; 600 W P_PPM; 100 A I_PPM; surface-mount format	Requires PCB re-layout; better suited for high-density designs with automated assembly	Select SMBJ180A when board space is constrained and SMT placement is preferred over through-hole mounting.
1.5KE180A	Same DO-41 package; 180 V V_BR; 1500 W P_PPM; 50 A I_PPM; higher surge capacity	Higher clamping voltage (269 V) and larger thermal mass; not AEC-Q101 qualified	Choose 1.5KE180A for non-automotive applications demanding higher single-event energy absorption.

Compared with P4KE180-E3/54, SMBJ180A offers superior surge handling in compact SMT form but lacks AEC-Q101 validation, while 1.5KE180A delivers greater pulse energy margin at the cost of higher clamping voltage and no automotive qualification-making P4KE180-E3/54 optimal for cost-sensitive, through-hole automotive and industrial designs requiring verified reliability.

FAQ

What is the clamping voltage of the P4KE180-E3/54 under standard 10/1000 μs surge conditions?

The P4KE180-E3/54 has a maximum clamping voltage (V_C) of 246 V at 1.6 A peak pulse current (I_PPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and ensures predictable overvoltage limiting during standardized surge events. The P4KE180-E3/54 maintains this clamping performance across its specified operating temperature range.

Is the P4KE180-E3/54 qualified for automotive applications?

Yes, the P4KE180-E3/54 is RoHS-compliant and meets AEC-Q101 qualification requirements for transient voltage suppressors. This certification confirms its suitability for automotive powertrain, body electronics, and infotainment systems where reliability under thermal cycling, vibration, and electrical stress is mandatory. The P4KE180-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified product documentation.

What does the "-E3/54" suffix indicate in P4KE180-E3/54?

The "-E3" suffix denotes RoHS-compliant construction with JESD 201 Class 1A whisker resistance, while "/54" specifies the preferred packaging code: 5500 units per 13-inch paper tape and reel. This ordering format ensures consistent logistics and automated assembly compatibility. The P4KE180-E3/54 is shipped in this configuration directly from Vishay's authorized distribution channels.

How does the P4KE180-E3/54 compare to bidirectional TVS diodes like P4KE180CA?

The P4KE180-E3/54 is unidirectional and features a cathode band marking, whereas P4KE180CA is bidirectional with no polarity marking and symmetric clamping in both directions. The P4KE180-E3/54 is intended for DC-biased lines where reverse conduction must be blocked; P4KE180CA suits AC-coupled or floating signal paths. Their V_BR and V_C values differ due to internal structure-P4KE180-E3/54 cannot substitute for P4KE180CA without circuit redesign.

What is the maximum junction temperature rating for the P4KE180-E3/54?

The P4KE180-E3/54 has a maximum junction temperature (T_J) rating of +175 °C, enabling operation in high-ambient environments such as engine compartments, industrial motor drives, and enclosed power supplies. This rating is validated per Vishay's thermal characterization data and supports derating curves up to 175 °C ambient when mounted with appropriate PCB copper area. The P4KE180-E3/54 maintains full electrical specifications within this thermal envelope.
