Product details

Overview

P6KE24-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 24 V breakdown voltage (V_BR = 22.8–25.2 V at I_T = 1.0 mA), 33.2 V maximum clamping voltage (V_C) at 18.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive body control modules to safeguard microcontrollers against load-dump transients.

For engineers reviewing the P6KE24-E3/54 datasheet, P6KE24-E3/54 pinout, P6KE24-E3/54 application, or P6KE24-E3/54 equivalent, key selection criteria include its DO-15 package compatibility, unidirectional polarity with cathode band marking, 20.5 V stand-off voltage (V_WM), and AEC-Q101 qualification for automotive-grade reliability under -55 °C to +175 °C junction temperature operation.

Technical Context

This TVS operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds V_BR, it avalanches into low-impedance conduction to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for suppressing ESD and inductive switching spikes before sensitive ICs are damaged.

The device is rated for 100 A non-repetitive forward surge current (I_FSM) and exhibits low incremental surge resistance, enabling effective clamping even during high-current transients. Thermal resistance of 20 °C/W (junction-to-lead) supports reliable power dissipation up to 5.0 W on an infinite heatsink at T_L = 75 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR (min/max)	22.8 V / 25.2 V at 1.0 mA test current - defines precise avalanche initiation threshold for predictable clamping onset
V_WM	20.5 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA, sets safe DC rail margin
V_C @ I_PPM	33.2 V at 18.1 A - clamped voltage seen by protected circuit during worst-case 600 W transient, determines stress on downstream components
P_PPM	600 W - peak surge power handling with 10/1000 µs waveform, validates suitability for ISO 7637-2 Pulse 5a/b load-dump events
I_FSM	100 A - single half-sine surge rating (8.3 ms), supports robustness against motor-commutation spikes in automotive actuators
T_J max.	+175 °C - extended junction temperature range enables placement near heat sources without derating loss
AEC-Q101	Qualified - certified for automotive electronic systems per stress-test requirements including HTOL, TC, and HAST

Pinout & Package

Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward conduction terminal	Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration
Cathode (banded end)	Reverse-biased avalanche terminal	Connected to protected line (e.g., 24 V supply rail); color band identifies polarity for correct PCB orientation

Key Features

Feature	Design Value
Glass passivated chip junction	Ensures stable, repeatable breakdown voltage across temperature and lifetime, minimizing parameter drift in harsh environments
600 W peak pulse power (10/1000 µs)	Provides proven immunity to high-energy transients such as ISO 16750-2 load dump and ISO 7637-2 Pulse 5a/b
Very fast response time (<1 ns)	Clamps before transient edge propagates into IC inputs, preventing latch-up or gate oxide damage in MOSFET drivers
AEC-Q101 qualified	Validates reliability for automotive applications including engine control units, lighting modules, and ADAS sensor interfaces
Low clamping ratio (V_C/V_BR ≈ 1.39)	Minimizes overvoltage stress on protected devices - e.g., keeps 3.3 V logic inputs below absolute maximum ratings during surges

Applications

Automotive Power Rail Protection	Industrial Sensor Interface Protection
Use Scenario: 24 V battery-fed ECUs exposed to load-dump transients up to 60 V during alternator regulation failure.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ24A	Same V_BR (24 V) and V_C (38.9 V), but SMC package (higher thermal mass), 600 W rating, AEC-Q101 qualified	Higher power density and better thermal performance in space-constrained layouts; requires different footprint	Select SMBJ24A when board layout allows SMC package and higher sustained surge capability is needed.
1.5KE24A	Same DO-15 package and V_BR, but lower 1.5 kW peak power rating and higher V_C (43 V); not AEC-Q101 qualified	Acceptable for commercial-grade industrial equipment where automotive qualification is unnecessary	Choose 1.5KE24A only for cost-sensitive non-automotive designs where 43 V clamping is acceptable.

Compared with SMBJ24A and 1.5KE24A, P6KE24-E3/54 offers optimal balance of AEC-Q101 compliance, DO-15 footprint compatibility, and 33.2 V clamping - making it the preferred choice for automotive and high-reliability industrial designs requiring drop-in replacement of legacy P6KE-series parts.

FAQ

What is the breakdown voltage tolerance for P6KE24-E3/54?

The P6KE24-E3/54 has a specified breakdown voltage range of 22.8 V to 25.2 V at 1.0 mA test current, representing ±5% tolerance around the nominal 24 V rating. This tight V_BR window ensures consistent clamping behavior across production lots and temperature ranges, critical for maintaining system-level overvoltage margins in automotive applications where P6KE24-E3/54 is commonly deployed.

Is P6KE24-E3/54 suitable for bi-directional transient protection?

No, P6KE24-E3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bi-directional protection, Vishay offers the P6KE24CA variant. Using P6KE24-E3/54 in AC or floating signal paths without proper polarity awareness risks forward conduction and failure; always verify circuit polarity before selecting P6KE24-E3/54.

What does the "E3/54" suffix mean in P6KE24-E3/54?

The "E3" denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred packaging code - 4000-piece 13-inch paper tape and reel. This format ensures automated pick-and-place compatibility and traceable sourcing, confirming that each P6KE24-E3/54 unit meets Vishay's standard for lead-free assembly and moisture sensitivity level (MSL) handling.

How does P6KE24-E3/54 perform under elevated ambient temperatures?

P6KE24-E3/54 derates linearly above 25 °C ambient: its peak pulse power drops to ~400 W at 85 °C and ~200 W at 125 °C per Vishay's Fig. 2 curve. The 175 °C maximum junction temperature and 20 °C/W junction-to-lead thermal resistance allow effective heat transfer to PCB copper, making P6KE24-E3/54 viable in under-hood automotive locations when mounted with adequate thermal relief.

Can P6KE24-E3/54 replace older P6KE24A parts in existing designs?

Yes, P6KE24-E3/54 is a direct functional and mechanical replacement for legacy P6KE24A, retaining identical DO-15 package dimensions, electrical specifications, and mounting footprint. The "E3" suffix adds RoHS compliance and enhanced whisker resistance, while maintaining full compatibility with existing schematics, layouts, and test procedures - no redesign or requalification is required when upgrading to P6KE24-E3/54.
