Product details
Overview
5.0SMDJ90AH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 5000W peak pulse power at 10/1000μs, 90V working standoff voltage, and 146V maximum clamping voltage at 34.3A peak current. It serves as primary overvoltage protection for DC power rails and I/O interfaces in automotive and industrial electronics.
For engineers reviewing the 5.0SMDJ90AH datasheet, 5.0SMDJ90AH pinout, 5.0SMDJ90AH application, or 5.0SMDJ90AH equivalent, key selection criteria include clamping voltage margin relative to system rail, junction temperature derating above 25°C, unidirectional polarity configuration, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode employs a stacked-die construction to achieve high surge capability in a compact SMC outline. Its photo-glass passivated junction ensures stable breakdown behavior and low leakage (<2µA at 90V), while the 1.0ps typical response time enables effective suppression of fast-rising ESD and lightning-induced transients.
The device operates across –55°C to +175°C junction temperature range and features a 16°C/W junction-to-lead thermal resistance when mounted on a 16mm × 16mm copper pad. Its 0.110 mV/°C temperature coefficient of VBR supports predictable voltage drift under thermal stress.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90A | Lower peak power rating (600W), same DO-214AA package, 146V clamping at 13.7A | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy transients like ESD or capacitive discharge | Select 5.0SMDJ90AH when 5000W surge immunity is required; SMBJ90A fits space-constrained designs where energy levels are lower. |
| SMCJ90A | Same DO-214AB (SMC) package and 5000W rating, but higher clamping voltage (150V at 33.3A) | Marginally tighter system-level voltage headroom due to +4V higher VC; identical thermal and mounting behavior | 5.0SMDJ90AH offers 4V lower clamping than SMCJ90A-critical for 120V-rated downstream components-while retaining full package compatibility. |
Compared with SMBJ90A and SMCJ90A, the 5.0SMDJ90AH delivers identical package fit and AEC-Q101 qualification as SMCJ90A but with superior clamping performance, while offering 8.3× higher surge capacity than SMBJ90A-making it the optimal choice for automotive and industrial 90V rail protection where voltage margin and reliability are prioritized.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ90AH under a 5000W surge?
The 5.0SMDJ90AH exhibits a maximum clamping voltage (VC) of 146 V when subjected to its rated 34.3 A peak pulse current, corresponding to the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during worst-case transients. The 5.0SMDJ90AH maintains this clamping performance consistently due to its stacked-die construction and photo-glass passivation.
Is the 5.0SMDJ90AH suitable for automotive applications?
Yes, the 5.0SMDJ90AH is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body control modules, and ADAS power supplies. Its –55°C to +175°C junction temperature range, 175°C maximum rating, and validated surge performance per ISO 7637-2 make it appropriate for under-hood and cabin environments. The 5.0SMDJ90AH meets stringent automotive reliability requirements without derating in most thermal layouts.
How does the 5.0SMDJ90AH differ from the 5.0SMDJ90A variant?
The "H" suffix in 5.0SMDJ90AH denotes AEC-Q101 qualification and enhanced process controls for automotive use, whereas the non-H version lacks formal automotive qualification. Both share identical electrical parameters and DO-214AB packaging, but the 5.0SMDJ90AH undergoes additional stress testing-including temperature cycling, highly accelerated life testing (HALT), and board-level reliability validation-to ensure compliance with automotive quality standards.
What is the polarity configuration of the 5.0SMDJ90AH?
The 5.0SMDJ90AH is a unidirectional TVS diode, meaning it functions as a Zener-like clamp only in reverse bias and conducts forward current like a standard diode. Polarity is indicated by a cathode band on the DO-214AB package body. In circuit implementation, the cathode connects to the line being protected, and the anode connects to ground or the reference potential-ensuring clamping action occurs only during overvoltage events on that line.
What thermal performance can be expected from the 5.0SMDJ90AH on a standard PCB?
When mounted on a 16 mm × 16 mm copper pad per JEDEC test conditions, the 5.0SMDJ90AH achieves a junction-to-lead thermal resistance (RθJL) of 16°C/W and a junction-to-ambient resistance (RθJA) of 61°C/W. This enables effective heat dissipation during repetitive surge events and supports continuous operation up to 6.25 W at TL = 75°C. The 5.0SMDJ90AH's thermal performance is optimized for standard FR-4 PCBs with adequate copper area and no additional heatsinking.
