Product details
Overview
SMCJ5.0AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping 5.0 V stand-off transients with 9.2 V max clamping voltage at 163 A peak pulse current. It delivers 1500 W peak pulse power dissipation using a 10/1000 µs waveform and operates across -55 °C to +150 °C junction temperature range. Used for protecting MOSFET gates, microcontroller I/O lines, and sensor signal paths against inductive switching surges.
For engineers reviewing the SMCJ5.0AHM3_A/H datasheet, SMCJ5.0AHM3_A/H pinout, SMCJ5.0AHM3_A/H application, or SMCJ5.0AHM3_A/H equivalent, key selection criteria include verified 5.0 V stand-off voltage, 9.2 V clamping under 163 A surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification status, and halogen-free RoHS-compliant construction per HM3 suffix.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for low incremental surge resistance and sub-nanosecond response time to transient overvoltages. Its breakdown voltage is specified at 6.40–7.07 V with 10 mA test current, ensuring reliable triggering before downstream IC damage occurs.
The device meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak, supports automated placement, and features matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Thermal resistance is 75 °C/W junction-to-ambient on standard 8.0 mm × 8.0 mm copper pads.

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients before reaching interface IC. Use Value: Limits voltage excursion to ≤9.2 V during 163 A surge, preserving signal integrity and preventing latch-up in 5 V-tolerant receivers. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V DC input lines, absorbing repetitive 1500 W surges without degradation. Use Value: Maintains 5.0 V stand-off while clamping to 9.2 V, enabling direct integration with 5 V logic-level optocouplers and level shifters. |
| Consumer Power Adapter Output | Medical Diagnostic Equipment Interface |
Use Scenario: Secondary-side overvoltage protection on USB-C PD and AC/DC adapter outputs subject to capacitor discharge transients. IC Role / Device Role / Timing Role: Fast-response TVS placed across output rails to suppress ringing and overshoot during load step changes. Use Value: Sub-ns response and 9.2 V clamping prevent false triggering or damage to downstream USB-PD controllers rated for 5.5 V max. | Use Scenario: ESD protection on patient-connected analog front-end channels (ECG, EEG) where low capacitance and high reliability are critical. IC Role / Device Role / Timing Role: Low-leakage (≤1000 µA at 5.0 V) unidirectional suppressor on signal path to ADC input stage. Use Value: Ensures <1 µA leakage at nominal 5 V bias, avoiding baseline drift in high-gain, low-noise amplifier stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-M3/A | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Suitable for space-constrained consumer PCBs with lower surge exposure | Select when board area is limited and peak surge energy does not exceed 400 W |
| SMCJ5.0AHE3_A/H | Same electrical specs but RoHS-compliant commercial grade (E3), not halogen-free or AEC-Q101 qualified | Appropriate for non-automotive industrial applications requiring cost-optimized sourcing | Choose when halogen-free and automotive qualification are not required |
Compared with SMCJ5.0AHM3_A/H, SMAJ5.0A-M3/A offers smaller size but reduced surge capacity, while SMCJ5.0AHE3_A/H matches performance but lacks halogen-free and AEC-Q101 validation-making SMCJ5.0AHM3_A/H optimal for automotive-grade designs needing full compliance assurance.

FAQ
What is the clamping voltage of SMCJ5.0AHM3_A/H at its rated peak pulse current?
The SMCJ5.0AHM3_A/H has a maximum clamping voltage (VC) of 9.2 V when subjected to its rated peak pulse current (IPPM) of 163 A using 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 the Vishay datasheet. The 9.2 V clamping ensures protected circuits remain within safe operating limits during surge events.
Is SMCJ5.0AHM3_A/H qualified for automotive applications?
Yes, SMCJ5.0AHM3_A/H is AEC-Q101 qualified, as confirmed by the HM3 suffix and documentation in Vishay's SMCJ5.0A–SMCJ188CA datasheet (Document Number 88394, Revision 09-Jan-2024). This qualification validates its suitability for automotive electronics including engine control, body electronics, and ADAS sensor interfaces where reliability under thermal cycling and mechanical stress is critical.
What does the "HM3" suffix indicate in SMCJ5.0AHM3_A/H?
The "HM3" suffix in SMCJ5.0AHM3_A/H denotes halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, distinguishing it from E3 (RoHS-only) and HE3/HM3 automotive variants. Per Vishay's ordering table, HM3 confirms both environmental compliance and AEC-Q101 qualification-making SMCJ5.0AHM3_A/H appropriate for automotive-grade production where material content and reliability standards are strictly enforced.
Can SMCJ5.0AHM3_A/H be used in bidirectional configurations?
No, SMCJ5.0AHM3_A/H is a unidirectional TVS diode, as indicated by the absence of "CA" suffix and explicit listing under unidirectional device rows in the Vishay datasheet. Bidirectional versions (e.g., SMCJ5.0CA) have symmetric breakdown in both polarities and no polarity marking; using SMCJ5.0AHM3_A/H in reverse-biased mode beyond its 5.0 V stand-off risks premature conduction and failure.
What is the thermal resistance of SMCJ5.0AHM3_A/H under standard mounting conditions?
The typical thermal resistance junction-to-ambient (RθJA) of SMCJ5.0AHM3_A/H is 75 °C/W when mounted on minimum recommended pad layout (0.31" × 0.31" copper pads per terminal), per Vishay's Thermal Characteristics table. This value assumes natural convection cooling and is essential for calculating junction temperature rise under steady-state power dissipation (PD = 6.5 W at TA = 50 °C).
