Product details
Overview
5.0SMDJ58AH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and I/O interfaces. It delivers 5000W peak pulse power at 10/1000μs, clamps transients to 93.6V at 53.5A, and features a 58V working standoff voltage with <2µA leakage. It is AEC-Q101 qualified and used in automotive body control modules and industrial power supplies.
For engineers reviewing the 5.0SMDJ58AH datasheet, 5.0SMDJ58AH pinout, 5.0SMDJ58AH application, or 5.0SMDJ58AH equivalent, key selection criteria include its DO-214AB (SMC) package, 64.4–71.2V breakdown range, 175°C max junction temperature, fast sub-1ps response, and RoHS/halogen-free compliance for automotive-grade reliability.
Technical Context
The 5.0SMDJ58AH employs a stacked-die construction in a unidirectional configuration, enabling high peak pulse power handling without polarity reversal. Its glass-passivated junction ensures stable breakdown characteristics and low leakage across temperature.
Thermal performance is defined by RθJL = 16°C/W and RθJA = 61°C/W on a 16mm × 16mm copper pad, supporting sustained operation up to 175°C junction temperature. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1.

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 (600W), same DO-214AA package, 58V VWM, 93.6V VC | Not suitable for ISO 7637-2 Pulse 5a (load dump); limited to lower-energy I/O protection | Select SMBJ58A only where surge energy is ≤600W and space constraints favor smaller DO-214AA footprint. |
| SMCJ58A | Same 5000W rating and DO-214AB package, but higher VBR min (64.4V) and identical VC (93.6V) | Functionally interchangeable in most 58V-rated systems; differs only in marking code and minor thermal test board variance | SMCJ58A is a direct functional alternative with identical electrical specs and mechanical fit-no PCB changes required. |
Compared with SMBJ58A and SMCJ58A, the 5.0SMDJ58AH provides identical clamping performance and AEC-Q101 qualification but distinguishes itself via tighter VBR tolerance (64.4–71.2V vs. 64.4–72.2V for SMCJ58A) and optimized thermal resistance (RθJL = 16°C/W) for high-reliability automotive deployments.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ58AH under rated surge current?
The 5.0SMDJ58AH has a maximum clamping voltage (VC) of 93.6 V at 53.5 A peak pulse current (IPP), measured per the 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuits during a 5000W transient event and is critical for ensuring downstream ICs remain within absolute maximum ratings. The 5.0SMDJ58AH maintains this clamping performance across its specified operating temperature range.
Is the 5.0SMDJ58AH suitable for automotive applications?
Yes, the 5.0SMDJ58AH is AEC-Q101 qualified and specifically designed for automotive use cases including body control modules, infotainment power rails, and ADAS sensor interfaces. Its 175°C maximum junction temperature, glass-passivated junction, and compliance with ISO 7637-2 load dump testing make it suitable for under-hood and cabin-mounted electronics. The 5.0SMDJ58AH also meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 requirements.
What is the breakdown voltage range for the 5.0SMDJ58AH?
The 5.0SMDJ58AH has a minimum breakdown voltage (VBR) of 64.4 V and a maximum of 71.2 V at 1 mA test current, as specified in the official Taiwan Semiconductor datasheet. This 6.8 V spread reflects manufacturing tolerance and ensures reliable turn-on behavior across production lots while maintaining compatibility with 58 V nominal systems. The 5.0SMDJ58AH's VBR exhibits a temperature coefficient of 0.107 mV/°C.
Does the 5.0SMDJ58AH have polarity markings, and how is it oriented on PCB?
Yes, the 5.0SMDJ58AH uses a cathode band marking on the DO-214AB (SMC) package to indicate polarity. During PCB layout, the banded end must be connected to the lower-potential node (typically ground or return path), while the anode connects to the line being protected. This orientation is essential for unidirectional operation-the 5.0SMDJ58AH will not conduct or clamp in reverse bias. The 5.0SMDJ58AH's polarity marking aligns with JEDEC-standard SMC device conventions.
What packaging and reel quantity is offered for the 5.0SMDJ58AH?
The 5.0SMDJ58AH is supplied in DO-214AB (SMC) package format on tape-and-reel, with 3,000 units per reel. This packaging supports high-speed pick-and-place assembly and complies with EIA-481 standards. The 5.0SMDJ58AH's tape design accommodates standard SMC feeders, and the matte tin-plated leads ensure solderability per J-STD-002. Reel labeling includes full part number, date code, and factory identifier per Taiwan Semiconductor's ordering specification.
