Product details
Overview
SMCJ90AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 90 V standoff voltage (VWM), 100–111 V breakdown range (VBR), and 1500 W peak pulse power (10/1000 µs). It clamps transients to ≤146 V at 10.3 A peak current and operates from –55 °C to +150 °C, targeting automotive-grade ESD and load-dump protection on power rails.
For engineers reviewing the SMCJ90AHM3_A/I datasheet, SMCJ90AHM3_A/I pinout, SMCJ90AHM3_A/I application, or SMCJ90AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, 1.0 µA max reverse leakage at VWM, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ps) and low incremental surge resistance, enabling effective suppression of inductive switching spikes and lightning-induced surges. Its unidirectional polarity features a cathode band marking and forward voltage of 3.5 V at 100 A.
The device meets MSL level 1 per J-STD-020 (260 °C peak reflow), has RθJA = 75 °C/W and RθJL = 15 °C/W, and is rated for non-repetitive 200 A surge (8.3 ms half-sine) - critical for automotive 12 V/24 V system compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 100 V / 111 V at 1 mA test current - ensures reliable breakdown within defined tolerance band |
| VC @ IPPM | 146 V at 10.3 A - clamping voltage limits downstream IC stress during 1500 W transient events |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves battery life and signal integrity in always-on circuits |
| PPPM | 1500 W (10/1000 µs) - handles high-energy surges common in automotive load-dump and industrial motor drives |
| TJ range | –55 °C to +150 °C - supports under-hood and industrial ambient operation without derating |
| AEC-Q101 | Qualified - validated for automotive reliability including temperature cycling, HTRB, and ESD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ90AHE3_A/I | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W), same VWM/VBR | Not suitable for automotive load-dump; limited to low-energy consumer surges | Select only when space-constrained and surge energy ≤400 W |
| SMCJ90A-M3/57T | Same electrical specs and SMC package, but commercial-grade (non-AEC-Q101), M3 suffix only (halogen-free/RoHS) | Lacks automotive qualification; acceptable for industrial controls without AEC requirements | Choose for cost-sensitive non-automotive designs requiring identical clamping performance |
Compared with SMCJ90AHM3_A/I, SMAJ90AHE3_A/I trades surge capacity for size, while SMCJ90A-M3/57T retains full electrical performance but omits AEC-Q101 validation - making the HM3 variant uniquely suited for production automotive systems requiring both qualification and 1500 W capability.

FAQ
What is the clamping voltage of the SMCJ90AHM3_A/I under maximum surge conditions?
The SMCJ90AHM3_A/I clamps to a maximum of 146 V at its rated peak pulse current of 10.3 A (10/1000 µs waveform). This value is measured under standardized test conditions with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC standards, ensuring repeatable protection performance in production layouts.
Is the SMCJ90AHM3_A/I suitable for automotive applications?
Yes, the SMCJ90AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction. Its 150 °C maximum junction temperature, 1500 W surge rating, and validation across temperature cycling and HTRB make it appropriate for under-hood and body-control module deployments where SMCJ90AHM3_A/I must survive load-dump and jump-start events.
How does the HM3 suffix differ from the M3 or E3 suffixes in the SMCJ90A family?
The HM3 suffix on SMCJ90AHM3_A/I denotes halogen-free, RoHS-compliant construction *and* AEC-Q101 qualification. In contrast, M3 indicates halogen-free/RoHS without automotive qualification, and E3 indicates RoHS-compliant but not halogen-free. Only HM3 and HE3 variants carry AEC-Q101 certification - confirming SMCJ90AHM3_A/I's suitability for automotive production.
What is the reverse leakage current specification for the SMCJ90AHM3_A/I at its standoff voltage?
The SMCJ90AHM3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 90 V standoff voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage minimizes quiescent power loss in battery-backed or energy-sensitive systems, directly supporting design goals for long-term reliability in always-on automotive modules using SMCJ90AHM3_A/I.
Can the SMCJ90AHM3_A/I be used in bidirectional configurations?
No, the SMCJ90AHM3_A/I is a unidirectional TVS diode, identified by its "A" suffix and cathode band marking. For bidirectional operation, Vishay specifies the "CA" suffix (e.g., SMCJ90CA). Using SMCJ90AHM3_A/I in reverse-biased configurations risks failure due to lack of symmetric breakdown characteristics - always verify polarity alignment in circuit layout for SMCJ90AHM3_A/I.
