Product details

Overview

5KP58-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 58 V stand-off voltage (V_WM), and 94 V clamping voltage (V_C) at 53.4 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.

For engineers reviewing the 5KP58-E3/73 datasheet, 5KP58-E3/73 pinout, 5KP58-E3/73 application, or 5KP58-E3/73 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal derating behavior, P600 mechanical dimensions, and real-world clamping performance under repetitive transients.

Technical Context

This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 64.4–71.2 V breakdown range (V_BR at 5 mA), then clamping to ≤94 V at 53.4 A. Its glass-passivated P600 junction enables fast response (<1 ns) and low incremental surge resistance for reliable crowbar replacement in switching power supply outputs.

Rated for -55 °C to +175 °C operation, it sustains 8.0 W steady-state power on infinite heatsink at T_L = 75 °C and withstands 600 A non-repetitive forward surge (8.3 ms half-sine). The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	58 V - Maximum continuous reverse operating voltage before conduction begins
V_BR (min/max)	64.4 V / 71.2 V at 5 mA - Guaranteed avalanche initiation range defining overvoltage trip threshold
V_C @ I_PPM	94 V at 53.4 A - Clamped voltage during 5000 W transient, limiting stress on downstream components
P_PPM	5000 W - Peak pulse power handling per 10/1000 μs waveform, enabling robust lightning/inductive-switching immunity
T_J max.	+175 °C - Maximum junction temperature allowing operation in under-hood automotive environments

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ58A-E3/52	Lower peak power (600 W), smaller SMB package, same V_WM (58 V) and V_C (93.6 V)	Suitable for board-level signal-line protection but not bulk DC bus clamping	Select when space-constrained and surge energy is ≤600 W (e.g., USB or CAN bus nodes)
1.5KE56A	Same P600 package, lower peak power (1500 W), V_WM = 47.8 V, V_C = 77 V at 19.4 A	Used where lower clamping voltage and reduced energy handling suffice (e.g., legacy 48 V systems)	Choose for cost-sensitive designs with <1500 W threat levels and tighter V_C budget

Compared with SMBJ58A-E3/52 and 1.5KE56A, the 5KP58-E3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, making it the only option among the three qualified for AEC-Q101 automotive load-dump protection and capable of replacing crowbar circuits in 58 V switching supplies.

FAQ

What is the clamping voltage of the 5KP58-E3/73 under maximum rated surge current?

The 5KP58-E3/73 clamps to a maximum of 94 V when subjected to its rated peak pulse current of 53.4 A (10/1000 μs waveform). This value is measured per JEDEC test conditions and ensures downstream components see no more than 94 V during worst-case transients, directly supporting design margin calculations for 100 V-rated ICs.

Is the 5KP58-E3/73 suitable for automotive applications?

Yes, the 5KP58-E3/73 is AEC-Q101 qualified and rated for operation from -55 °C to +175 °C, making it suitable for under-hood and powertrain applications. Its 5000 W surge rating and robust P600 package meet ISO 7637-2 Pulse 5a load-dump requirements when properly mounted on adequate copper area for thermal dissipation.

Does the 5KP58-E3/73 have bidirectional capability?

No, the 5KP58-E3/73 is unidirectional only, with polarity indicated by a cathode band. It conducts in reverse breakdown above V_BR and blocks forward current up to 3.5 V at 100 A. For AC or bipolar protection, a separate bidirectional part such as 5KP58CA must be selected.

What is the maximum steady-state power dissipation for the 5KP58-E3/73?

The 5KP58-E3/73 dissipates up to 8.0 W continuously when mounted on an infinite heatsink at lead temperature T_L = 75 °C, per Figure 5 in the Vishay datasheet. Derating is required above 75 °C lead temperature, reaching zero allowable power at 175 °C junction temperature.

How does the 5KP58-E3/73 compare to standard 1.5 kW TVS diodes like 1.5KE56A?

The 5KP58-E3/73 provides 3.3× higher peak pulse power (5000 W vs. 1500 W), higher clamping voltage (94 V vs. 77 V), and broader V_BR tolerance (64.4–71.2 V vs. 60.7–67.1 V) than 1.5KE56A. It is physically larger (P600 vs. DO-201), supports higher surge repetition rates, and carries AEC-Q101 qualification-making it appropriate for demanding automotive and industrial DC bus protection where 1.5KE56A would fail catastrophically.
