Product details

Overview

5KP64-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 64 V stand-off voltage (V_WM), and 103 V clamping voltage (V_C) at 48.5 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive power supplies and industrial switching systems.

For engineers reviewing the 5KP64-E3/73 datasheet, 5KP64-E3/73 pinout, 5KP64-E3/73 application, or 5KP64-E3/73 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and compatibility with 275 °C solder dip per JESD 22-B106 - critical for under-hood automotive and high-reliability industrial designs.

Technical Context

This TVS diode operates as a voltage-clamping overvoltage protection device, triggered when reverse voltage exceeds its breakdown threshold (71.1–78.6 V at 5 mA). Its glass-passivated P600 chip junction enables fast response (<1 ns) and stable clamping during repetitive transients induced by inductive load switching or lightning surges.

It is rated for non-repetitive 10/1000 μs waveform pulses at 0.01% duty cycle, with thermal derating above 25 °C ambient and maximum forward surge current of 600 A (8.3 ms half-sine). The device exhibits +0.108 %/°C temperature coefficient of V_BR, ensuring predictable voltage drift across operating range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM (Stand-off)	64 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below circuit rail.
V_BR (Breakdown)	71.1–78.6 V at 5 mA - Voltage at which device enters avalanche conduction; ensures reliable turn-on without premature triggering.
V_C (Clamping)	103 V at 48.5 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress.
P_PPM	5000 W - Peak pulse power handling capability; supports high-energy transients common in automotive load-dump events.
T_J max	175 °C - Maximum junction temperature; enables operation in under-hood environments and high-power 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
SMBJ64A-E3/52	Lower peak power (600 W), smaller SMB package, same V_WM/V_C ratings	Not suitable for load dump; limited to ESD/EFT-level transients in space-constrained PCBs	Select when board area is constrained and surge energy is ≤600 W (e.g., consumer IoT sensor nodes).
1.5KE68A	Same P600 package, lower peak power (1500 W), higher V_C (118 V at 12.7 A)	Inadequate for 5000 W automotive load dump; acceptable for industrial AC line filtering	Choose only if cost sensitivity outweighs energy-handling requirement and thermal margin permits.

Compared with SMBJ64A-E3/52 and 1.5KE68A, the 5KP64-E3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, enabling single-device compliance with ISO 7637-2 Pulse 5a while maintaining tight clamping and AEC-Q101 validation - essential for mission-critical automotive and industrial power rails.

FAQ

What is the clamping voltage of the 5KP64-E3/73 under standard test conditions?

The 5KP64-E3/73 has a maximum clamping voltage (V_C) of 103 V at 48.5 A peak pulse current with a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events - critical for ensuring downstream components remain within their absolute maximum ratings.

Is the 5KP64-E3/73 suitable for automotive applications?

Yes, the 5KP64-E3/73 is AEC-Q101 qualified and explicitly designed for automotive use cases including engine control units, body electronics, and ADAS power domains. Its 175 °C junction rating, robust P600 package, and 5000 W pulse capability meet ISO 7637-2 Load Dump requirements - making it a validated choice for under-hood and chassis-mounted systems.

What does the "E3/73" suffix indicate in 5KP64-E3/73?

The "E3" denotes RoHS-compliant, commercial-grade construction meeting JESD 201 Class 1A whisker testing, while "/73" specifies the packaging format: 73 = 800-piece tape-and-reel on 13-inch diameter reel. This differs from /54 (same quantity, 7-inch reel) and confirms full traceability and assembly compatibility for automated SMT lines.

How does the 5KP64-E3/73 compare to bidirectional TVS diodes?

The 5KP64-E3/73 is unidirectional and intended for DC-biased applications where reverse conduction must be blocked during normal operation. Unlike bidirectional variants, it provides no protection against positive transients on grounded lines - so it must be placed with cathode toward the protected rail. Its lower leakage (<2 μA at 64 V) and tighter V_BR tolerance suit precision DC systems.

Can the 5KP64-E3/73 replace older 1.5KE-series TVS diodes?

No direct replacement: the 5KP64-E3/73 offers 3.3× higher peak pulse power (5000 W vs. 1500 W) and lower clamping voltage (103 V vs. 118 V) than 1.5KE68A, but shares the P600 package. Substitution requires verifying board thermal design, surge energy profile, and layout clearance - especially since 5KP64-E3/73 draws more heat during clamping and demands adequate copper pour for heatsinking.
