Product details

Overview

5KP54A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 5000 W peak pulse power (10/1000 µs), 54 V stand-off voltage (V_WM), 60–66.3 V breakdown range (V_BR), and clamps to ≤87.1 V at 57.4 A peak pulse current - used in automotive power supply overvoltage protection and industrial sensor interface circuits.

For engineers reviewing the 5KP54A-E3/54 datasheet, 5KP54A-E3/54 pinout, 5KP54A-E3/54 application, or 5KP54A-E3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, P600 thermal performance, 175 °C max junction temperature, and compatibility with 8.3 ms surge waveforms per JEDEC standards.

Technical Context

The 5KP54A-E3/54 operates as a silicon avalanche diode with glass-passivated P600 chip junction, optimized for non-repetitive transient suppression. Its clamping behavior is defined by low incremental surge resistance and fast response time (<1 ns), enabling effective protection against lightning-induced surges and inductive switching transients.

It is rated for 500 A peak forward surge current (I_FSM, 8.3 ms half-sine), dissipates 8.0 W on infinite heatsink at T_L = 75 °C, and exhibits a V_BR temperature coefficient of 0.107 %/°C - confirming stable breakdown across automotive-grade operating temperatures (−55 °C to +175 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	54 V - maximum continuous reverse working voltage before clamping begins; sets safe operating margin for 48 V nominal systems.
V_BR (min/max)	60.0 V / 66.3 V at 5 mA - verified avalanche onset range; ensures predictable turn-on under surge conditions.
V_C @ I_PPM	≤87.1 V at 57.4 A - clamped voltage during 5000 W transient; determines protected circuit's maximum stress level.
P_PPM	5000 W (10/1000 µs) - peak pulse power handling; supports IEC 61000-4-5 Level 4 surge immunity compliance.
I_FSM	500 A (8.3 ms half-sine) - surge current withstand without failure; enables fuse/breaker coordination in crowbar-style protection.
T_J max.	+175 °C - maximum junction temperature; allows operation in under-hood automotive environments and high-ambient industrial settings.
Polarity	Unidirectional - cathode marked by color band; suitable for DC-biased rail protection only (not AC or bidirectional signals).

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ54A	600 W peak power (vs. 5000 W), DO-214AA package, lower I_PPM (33.3 A)	Targeted at low-energy signal-line protection; insufficient for load dump or lightning-level surges.	Select SMBJ54A only for PCB space-constrained designs where surge energy is limited to <100 mJ.
1.5KE56A	1500 W peak power, DO-201AD package, higher V_C (93.6 V at 16.1 A), no AEC-Q101 qualification	Designed for general-purpose industrial use; lacks automotive reliability validation and thermal robustness.	Choose 1.5KE56A for cost-sensitive non-automotive applications where 5000 W capability is not required.

Compared with SMBJ54A and 1.5KE56A, the 5KP54A-E3/54 delivers 3.3× higher peak power than 1.5KE56A and over 8× that of SMBJ54A, with AEC-Q101 qualification and P600 thermal mass enabling sustained surge handling in harsh environments - making it uniquely suited for automotive and heavy-industrial primary rail protection.

FAQ

What is the clamping voltage of the 5KP54A-E3/54 under maximum surge conditions?

The 5KP54A-E3/54 clamps to a maximum of 87.1 V when subjected to its rated peak pulse current of 57.4 A (10/1000 µs waveform). This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings. The 5KP54A-E3/54 achieves this with low incremental surge resistance and fast avalanche response.

Is the 5KP54A-E3/54 suitable for automotive applications?

Yes, the 5KP54A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments with operating junction temperatures up to +175 °C. Its P600 package provides thermal mass for transient energy dissipation, and its 5000 W surge rating meets ISO 16750-2 load dump requirements. The 5KP54A-E3/54 is commonly deployed in 48 V battery management and ADAS power modules.

What does the "E3/54" suffix mean in 5KP54A-E3/54?

The "E3" denotes RoHS-compliant, commercial-grade construction meeting JESD 201 Class 1A whisker resistance, while "/54" specifies the preferred packaging code: 800-unit quantity on 13-inch paper tape and reel. This ordering format ensures consistent logistics and SMT placement compatibility. The 5KP54A-E3/54 is distinct from HE3 variants, which carry AEC-Q101 qualification and different revision coding.

Can the 5KP54A-E3/54 be used in bidirectional signal protection?

No, the 5KP54A-E3/54 is unidirectional only, with cathode marked by a color band. It protects against positive transients on a DC-biased line referenced to ground. For bidirectional or AC-coupled signal lines, a dual-diode configuration or dedicated bidirectional TVS (e.g., 5KP54CA) is required. Using the 5KP54A-E3/54 in reverse-biased signal paths risks forward conduction and unintended loading.

How does the 5KP54A-E3/54 compare to standard Zener diodes for surge protection?

Unlike standard Zener diodes, the 5KP54A-E3/54 is engineered for high-energy transient suppression: it handles 5000 W pulses (vs. typically <5 W for Zeners), exhibits faster response (<1 ns vs. >10 ns), and maintains stable clamping under extreme current slew rates. Its P600 package and glass-passivated junction ensure reliability under repeated surges - whereas Zeners degrade rapidly under similar conditions. The 5KP54A-E3/54 is not a voltage regulator but a dedicated surge limiter.
