Product details
Overview
SMCJ90AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 90 V stand-off voltage (VWM), 100–111 V breakdown voltage (VBR), 146 V maximum clamping voltage (VC) at 10.3 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive power electronics, industrial motor drives, and telecom interface protection.
For engineers reviewing the SMCJ90AHE3_A/H datasheet, SMCJ90AHE3_A/H pinout, SMCJ90AHE3_A/H application, or SMCJ90AHE3_A/H equivalent, key selection criteria include clamping performance under 10.3 A surge, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging an avalanche breakdown mechanism to limit transient voltages above its VBR threshold. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ps), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
Designed for high-reliability environments, SMCJ90AHE3_A/H meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), supports 200 A non-repetitive forward surge (IFSM), and maintains operation across -55 °C to +150 °C junction temperature range - critical for under-hood automotive and industrial control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 100 V / 111 V at 1.0 mA test current - defines reliable avalanche onset window |
| VC @ IPPM | 146 V at 10.3 A - peak clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 1500 W - peak transient energy absorption capability under standardized waveform |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90AHE3_A/H | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VBR/VC specs | Not suitable for 1500 W surge events; limited to lower-energy transients in space-constrained designs | Select only when board area is critical and peak surge energy remains ≤600 W |
| SMCJ90CAHE3_A/H | Bidirectional variant; identical VWM/VBR/VC/PPPM but symmetrical clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose when protecting bidirectional interfaces like Ethernet PHYs or analog sensor bridges |
Compared with SMCJ90AHE3_A/H, SMBJ90AHE3_A/H trades surge capacity for footprint reduction, while SMCJ90CAHE3_A/H adds polarity symmetry at no clamping performance cost - enabling precise matching to circuit topology and threat profile.

FAQ
What is the clamping voltage of SMCJ90AHE3_A/H at its rated peak pulse current?
The SMCJ90AHE3_A/H has a maximum clamping voltage (VC) of 146 V when subjected to its rated peak pulse current (IPPM) of 10.3 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events - a critical parameter for ensuring downstream components remain within safe operating limits. The SMCJ90AHE3_A/H achieves this clamping performance while maintaining low leakage and thermal stability.
Is SMCJ90AHE3_A/H qualified for automotive applications?
Yes, SMCJ90AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in the SMCJ5.0A–SMCJ188CA datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - validating suitability for under-hood and chassis-mounted automotive electronics. The SMCJ90AHE3_A/H meets these requirements without derating in its specified -55 °C to +150 °C operating range.
What does the "HE3" suffix indicate in SMCJ90AHE3_A/H?
The "HE3" suffix in SMCJ90AHE3_A/H denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade "E3" variants. Per Vishay's ordering information, "HE3" parts use matte tin-plated leads, meet JESD 201 Class 2 whisker resistance, and are rated for automotive reliability. The "_A/H" further specifies packaging: 7-inch tape-and-reel (H) with revision A. This coding ensures traceability, compliance, and application-grade assurance for the SMCJ90AHE3_A/H.
How does SMCJ90AHE3_A/H differ from SMCJ90CAHE3_A/H?
SMCJ90AHE3_A/H is unidirectional, with polarity marked by a cathode band and optimized for DC rail protection, whereas SMCJ90CAHE3_A/H is bidirectional - offering symmetrical clamping in both directions with no polarity marking. Both share identical VWM (90 V), VBR (100–111 V), VC (146 V), and PPPM (1500 W), but the SMCJ90CAHE3_A/H is required for AC-coupled or floating nodes. The SMCJ90AHE3_A/H cannot substitute for the CA version in bidirectional applications without risking failure during reverse-polarity transients.
What is the thermal resistance of SMCJ90AHE3_A/H, and how does it affect PCB layout?
The SMCJ90AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value directly impacts sustained power dissipation: at 6.5 W rated power, junction temperature rise reaches ~488 °C above ambient - hence derating is essential. For reliable operation, designers must use adequate copper area and consider RθJL (15 °C/W) for lead-based heat conduction. The SMCJ90AHE3_A/H thermal behavior is validated per JEDEC standards and documented in Vishay's thermal characteristics table.
