Product details
Overview
5KP58HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR), 94 V clamping voltage (VC) at 53.4 A peak pulse current, and 5000 W peak pulse power (10/1000 µs). It is AEC-Q101 qualified and used to protect automotive power supplies and industrial control inputs against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 5KP58HE3/73 datasheet, 5KP58HE3/73 pinout, 5KP58HE3/73 application, or 5KP58HE3/73 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, clamping performance under standardized surge waveforms, thermal derating behavior, and RoHS-compliant packaging details - all critical for automotive-grade overvoltage protection design validation.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device: when reverse voltage exceeds VBR, it avalanches rapidly (<1 ns response) to limit transient energy across protected circuitry. Its P600 glass-passivated junction enables stable 5000 W surge handling with low incremental surge resistance (Rdyn ≈ 1.76 Ω, derived from ΔVC/ΔIPPM).
Thermal management relies on lead temperature (TL) derating: power dissipation drops from 8.0 W at TL = 75 °C to zero at 175 °C junction max. The uni-directional polarity (cathode band marked) supports DC-biased rail protection only - not AC line or bidirectional signal applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before leakage exceeds 2 µA; sets upper limit for protected DC rail voltage. |
| VBR @ IT = 50 mA | 64.4–71.2 V - Breakdown threshold range; ensures reliable conduction onset during transients without premature triggering. |
| VC @ IPPM = 53.4 A | 94 V - Clamped voltage during 10/1000 µs surge; defines maximum stress imposed on downstream ICs or MOSFETs. |
| PPPM | 5000 W - Peak pulse power rating; validates capability to absorb lightning surges (IEC 61000-4-5 Level 4) without failure. |

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 | Lower peak power (600 W), smaller SMB package, same VWM = 58 V, higher VC = 93.6 V at 6.4 A. | Suitable for board-level signal line protection; insufficient for load dump or crowbar use due to power limitation. | Select SMBJ58A only for space-constrained, low-energy surge scenarios - not for automotive power rail protection. |
| 1.5KE56A | Same P600 package, lower peak power (1500 W), VWM = 56 V, VC = 93.6 V at 16.1 A, non-AEC-Q101. | Acceptable for industrial power supplies lacking automotive qualification; cannot meet ISO 16750-2 load dump requirements. | Choose 1.5KE56A for cost-sensitive non-automotive designs where 5000 W rating is unnecessary. |
Compared with SMBJ58A and 1.5KE56A, the 5KP58HE3/73 uniquely combines AEC-Q101 qualification, 5000 W surge capacity, and P600 thermal mass - making it the only option among the three validated for under-hood automotive power rail protection per ISO 7637-2.

FAQ
What is the clamping voltage of the 5KP58HE3/73 under a 10/1000 µs surge?
The 5KP58HE3/73 clamps to a maximum of 94 V when subjected to its rated peak pulse current of 53.4 A using the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the upper bound of voltage seen by protected circuitry during worst-case transient events - critical for ensuring downstream components remain within absolute maximum ratings.
Is the 5KP58HE3/73 suitable for bidirectional signal line protection?
No, the 5KP58HE3/73 is a unidirectional TVS diode and must be used only on DC-biased lines where reverse polarity is defined. It lacks symmetrical breakdown characteristics required for AC or bidirectional data lines. For such applications, a dedicated bidirectional part like 5KP58CA would be necessary - the 5KP58HE3/73 will not conduct in forward direction during normal operation but cannot suppress positive-going transients on grounded lines.
Does the HE3 suffix on 5KP58HE3/73 indicate AEC-Q101 qualification?
Yes, the HE3 suffix explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature. This includes full stress testing per the AEC-Q101 standard - including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling - confirming suitability for automotive under-hood applications where reliability under thermal and mechanical stress is mandatory.
How does the 5KP58HE3/73 compare to standard 1.5 kW TVS diodes in surge handling?
The 5KP58HE3/73 delivers over three times the peak pulse power (5000 W vs. 1500 W) of typical 1.5KE-series devices, achieved through larger P600 die area and optimized thermal path. This allows it to absorb IEC 61000-4-5 Level 4 surges without degradation, whereas 1.5KE56A fails catastrophically under identical conditions - making the 5KP58HE3/73 essential for high-reliability automotive and industrial power protection.
What is the maximum allowable lead temperature during soldering for the 5KP58HE3/73?
The 5KP58HE3/73 supports solder dip at up to 275 °C for 10 seconds maximum, per JESD 22-B106. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability, and the HE3 suffix confirms JESD 201 Class 2 whisker resistance - ensuring robustness during both wave and reflow assembly processes without compromising junction integrity.
