Product details
Overview
SMCJ6.0AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 10.3 V maximum clamping voltage at 145.6 A peak pulse current and 6.0 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supply rails.
For engineers reviewing the SMCJ6.0AHM3_A/H datasheet, SMCJ6.0AHM3_A/H pinout, SMCJ6.0AHM3_A/H application, or SMCJ6.0AHM3_A/H equivalent, key selection criteria include its 6.67–7.37 V breakdown voltage range at 10 mA, 1000 μA max reverse leakage at 6.0 V, AEC-Q101 qualification status, halogen-free RoHS compliance, and SMC package thermal resistance of 75 °C/W junction-to-ambient.
Technical Context
This TVS diode operates as a unidirectional clamping device with a glass-passivated silicon junction, optimized for fast response to 10/1000 μs surge waveforms. Its low incremental surge resistance and 0.059 %/°C temperature coefficient of VBR ensure stable clamping performance across temperature.
The device is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020, and features matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Polarity is marked by a cathode band on the SMC package body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 6.67 V to 7.37 V at IT = 10 mA - defines reliable conduction onset under transient stress |
| VWM | 6.0 V - maximum continuous reverse working voltage before leakage exceeds 1000 μA |
| IPPM | 145.6 A at 10/1000 μs waveform - peak surge current it can safely clamp without failure |
| VC | 10.3 V at IPPM - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 1500 W - peak pulse power handling capability under standardized surge conditions |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance indicating required PCB copper area for thermal management |

| Glass passivated junction | Provides stable leakage performance and long-term reliability under humidity and bias stress |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 5–6 V microcontroller supply rails from load-dump and alternator ripple transients in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between VCC and GND, conducting only during overvoltage events. Use Value: Limits voltage to ≤10.3 V during 145.6 A surges, preventing latch-up or gate oxide damage in downstream logic. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA transmitter outputs) from ESD and inductive switching noise in factory automation systems. IC Role / Device Role / Timing Role: Standby protection element connected in parallel with signal path, inactive until transient exceeds 6.67 V. Use Value: Clamps sub-100 ns ESD events to <10.3 V while adding only 1.0 μA leakage at 6.0 V, preserving signal integrity. |
| DC-DC Converter Input Stage | Consumer Power Adapter Surge Protection |
Use Scenario: Front-end transient suppression on 6 V input of buck converter powering infotainment subsystems. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of input capacitor and controller IC. Use Value: Absorbs 1500 W pulses without degradation, maintaining <1000 μA leakage to avoid quiescent current impact. | Use Scenario: Secondary-side protection on 6 V USB-C PD output rails in portable chargers exposed to user-handling ESD. IC Role / Device Role / Timing Role: Fast-response shunt device placed adjacent to connector, referenced to local ground plane. Use Value: Responds within picoseconds to 8 kV contact discharge, limiting peak voltage to 10.3 V with no recovery delay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0AHE3/A | Lower PPPM (400 W), SMA package (higher RθJA = 105 °C/W), same VWM/VBR range | Suitable for lower-energy surges; not recommended for automotive load-dump where 1500 W is required | Select SMCJ6.0AHM3_A/H when full AEC-Q101 qualification and 1500 W clamping are mandatory |
| SMCJ6.0A-E3/57T | Same electrical specs and SMC package, but commercial-grade (non-AEC-Q101), RoHS-compliant without halogen-free assurance | Acceptable for industrial control panels but not for automotive OEM or Tier-1 production | Choose SMCJ6.0AHM3_A/H for halogen-free compliance and certified automotive qualification |
Compared with SMAJ6.0AHE3/A and SMCJ6.0A-E3/57T, the SMCJ6.0AHM3_A/H delivers higher surge robustness, automotive-grade reliability, and halogen-free construction - critical for under-hood and safety-critical 6 V rail protection where long-term field stability is non-negotiable.

FAQ
What is the breakdown voltage tolerance of SMCJ6.0AHM3_A/H?
The SMCJ6.0AHM3_A/H has a specified breakdown voltage range of 6.67 V to 7.37 V at 10 mA test current, corresponding to ±10.4% tolerance around the nominal 6.0 V stand-off rating. This ensures consistent turn-on behavior across production lots while accommodating process variation without compromising protection margin.
Is SMCJ6.0AHM3_A/H suitable for bidirectional transient protection?
No, SMCJ6.0AHM3_A/H is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, select the "CA" variant (e.g., SMCJ6.0CA). Using SMCJ6.0AHM3_A/H on AC or floating signal lines risks forward conduction and failure during negative transients.
Does SMCJ6.0AHM3_A/H require derating at elevated ambient temperatures?
Yes, SMCJ6.0AHM3_A/H must be derated above 25 °C ambient per Figure 2 in the datasheet. At 85 °C ambient, its 1500 W peak pulse power rating drops to approximately 750 W, and its 145.6 A IPPM reduces proportionally. Thermal design must account for RθJA = 75 °C/W and PCB copper pad area per specification.
What does the "HM3" suffix indicate in SMCJ6.0AHM3_A/H?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" specifies the tape-and-reel packaging option (850 units per 7″ reel), and "_A/H" indicates revision level A in that packaging configuration. This distinguishes it from commercial-grade "E3" or non-halogen-free "HE3" variants.
Can SMCJ6.0AHM3_A/H replace SMCJ6.0A-E3/57T in an existing design?
Yes, SMCJ6.0AHM3_A/H is pin-compatible and electrically identical to SMCJ6.0A-E3/57T, but adds AEC-Q101 qualification and halogen-free materials. No PCB changes are needed; however, qualification testing per automotive standards is required if migrating to safety-critical applications where the original part lacked AEC-Q101 validation.
