Product details

Overview

P4KE530-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for primary overvoltage protection of sensitive electronics. It features a 530 V breakdown voltage (V_BR), 760 V clamping voltage (V_C) at 400 mA, 300 W peak pulse power (10/1000 µs), and operates from –55 °C to +150 °C - deployed in power supply input stages, MOSFET gate protection, and sensor signal line surge suppression.

For engineers reviewing the P4KE530-E3/54 datasheet, P4KE530-E3/54 pinout, P4KE530-E3/54 application, or P4KE530-E3/54 equivalent, key selection considerations include unidirectional polarity, DO-41 mechanical compatibility, 477 V stand-off voltage (V_WM), 1.0 µA reverse leakage at V_WM, and thermal resistance (R_θJA = 125 °C/W) for PCB layout derating.

Technical Context

This TVS diode uses a glass-passivated silicon junction to achieve fast response (<1 ns) and low incremental surge resistance, enabling effective clamping of transient energy from inductive switching or lightning-induced surges. Its unidirectional configuration provides reverse-biased protection only, with cathode denoted by a color band on the DO-41 body.

Clamping performance is defined under standardized 10/1000 µs waveform testing; V_C = 760 V at I_PP = 400 mA reflects actual voltage seen by protected circuitry during surge events. Temperature coefficient of V_BR is +650 mV/°C, requiring thermal-aware placement near heat sources.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR (min)	530 V - guaranteed minimum breakdown voltage at 100 µA test current; sets lower limit for conduction onset.
V_WM	477 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC blocking level.
V_C @ 400 mA	760 V - clamped voltage during 10/1000 µs surge; determines worst-case stress on downstream ICs.
P_PPM	300 W - peak pulse power handling capability; defines single-event surge energy absorption capacity.
I_D @ V_WM	1.0 µA - reverse leakage at stand-off voltage; ensures minimal quiescent power loss in high-impedance circuits.
T_J max	+150 °C - maximum junction temperature; constrains thermal design margin for sustained power dissipation.
C_J @ 1 MHz, 0 V	90 pF - junction capacitance at zero bias; impacts high-frequency signal integrity in data line protection.

Pinout & Package

Package: DO-41 (DO-204AL), axial-leaded, molded epoxy case with matte tin-plated leads; cathode indicated by color band. RoHS-compliant (E3 suffix), JESD201 Class 1A whisker tested.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ530A-E3/52	Surface-mount SMB package; same V_BR (530 V), lower V_C (773 V), higher P_PPM (600 W).	Requires PCB redesign for SMD footprint; better suited for automated assembly and space-constrained layouts.	Select when board real estate is limited and higher surge rating is needed without axial lead constraints.
1N5375B	Unidirectional Zener diode (not TVS-optimized); V_Z = 530 V, but no specified 10/1000 µs P_PPM or V_C rating.	Lacks validated surge waveform performance; unsuitable for IEC 61000-4-5 compliance-critical designs.	Only consider for non-safety-critical, low-energy DC regulation where clamping speed and surge rating are secondary.

Compared with SMBJ530A-E3/52 and 1N5375B, the P4KE530-E3/54 delivers proven 300 W transient absorption in through-hole DO-41 format with documented V_C and thermal resistance - making it preferred for legacy industrial controls, field-serviceable modules, and prototyping where leaded components simplify hand-soldering and replacement.

FAQ

What is the polarity configuration of the P4KE530-E3/54?

The P4KE530-E3/54 is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage. The cathode is marked by a color band on the DO-41 package body; correct orientation is essential for proper clamping function in DC circuits. Unlike bidirectional variants, it does not protect against negative transients on positive rails without additional circuitry.

How does the P4KE530-E3/54 differ from the P4KE550-E3/54?

The P4KE530-E3/54 has a minimum breakdown voltage of 530 V and stand-off voltage of 477 V, whereas the P4KE550-E3/54 specifies 550 V V_BR (min) and 495 V V_WM. Both share identical package, P_PPM (300 W), V_C (760 V), and thermal ratings. Select P4KE530-E3/54 when system operating voltage requires tighter margin below 477 V DC.

What is the maximum clamping voltage for the P4KE530-E3/54 under surge conditions?

The P4KE530-E3/54 has a maximum clamping voltage (V_C) of 760 V when subjected to a 400 mA, 10/1000 µs waveform - the industry-standard surge test condition. This value represents the peak voltage imposed on the protected circuit during transient conduction and is critical for ensuring downstream components remain within their absolute maximum ratings.

Can the P4KE530-E3/54 be used in bidirectional protection applications?

No, the P4KE530-E3/54 is strictly unidirectional and cannot provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, use a dedicated bidirectional TVS such as the P4KE530A-E3/54 or series-connected unidirectional pairs. Using P4KE530-E3/54 in reverse-biased AC configurations may result in permanent failure due to forward conduction during negative half-cycles.

What is the thermal resistance specification for the P4KE530-E3/54?

The P4KE530-E3/54 has a typical junction-to-ambient thermal resistance (R_θJA) of 125 °C/W under standard test conditions (free-air, no heatsink). Its junction-to-lead resistance (R_θJL) is 75 °C/W. These values inform PCB copper pour sizing and layout spacing to maintain T_J ≤ 150 °C during repetitive surge events or elevated ambient temperatures.
