Product details
Overview
SMBJ6.0AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps transients to ≤10.3 V at 58.3 A, making it suitable for safeguarding MOSFET gates, microcontroller I/O, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ6.0AHM3/I datasheet, SMBJ6.0AHM3/I pinout, SMBJ6.0AHM3/I application, or SMBJ6.0AHM3/I equivalent, this device is evaluated for robust ESD and surge immunity in 24 V automotive control modules, USB-C power delivery input stages, and PLC analog input protection where low clamping voltage and AEC-Q101-qualified reliability are required.
Technical Context
This TVS operates as a unidirectional avalanche diode with cathode-band polarity marking, optimized for clamping fast-rising transients (response time <1 ps) while maintaining low incremental surge resistance. Its glass-passivated junction ensures stable VBR tolerance (±5%) and thermal stability up to 150 °C junction temperature.
Rated for 600 W peak pulse power under standardized 10/1000 µs waveform, it delivers 58.3 A maximum peak pulse current (IPPM) and exhibits 0.059 %/°C temperature coefficient of VBR, enabling predictable performance across automotive and industrial ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before leakage exceeds 800 µA; sets upper limit for protected circuit DC bias. |
| VBR @ IT = 10 mA | 6.67–7.37 V - Confirmed breakdown range ensuring reliable turn-on during overvoltage events without premature conduction. |
| VC @ IPPM = 58.3 A | ≤10.3 V - Clamping voltage limiting stress on downstream ICs during 600 W surge; critical for 5 V logic-level protection. |
| PPPM | 600 W - Peak pulse power handling capability per 10/1000 µs waveform, defining surge energy absorption capacity. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine), supporting inrush current immunity in power rail applications. |
| TJmax | +150 °C - Maximum junction temperature enabling operation in under-hood automotive and high-temperature industrial enclosures. |
| Package | SMB (DO-214AA) - Surface-mount package with 5.59 mm × 4.06 mm footprint, MSL Level 1 compliant, compatible with automated reflow assembly. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode identified by a band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during reverse-biased surge events. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 24 V rail or sensor output); conducts avalanche current when VIN exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - enables use in engine control units without derating. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Meets IEC 61249-2-21 and JEDEC J-STD-020 MSL Level 1 - supports lead-free reflow and environmental compliance in global OEM BOMs. |
| 600 W peak pulse power (10/1000 µs) | Handles IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) without degradation when mounted on 5 mm × 5 mm copper pads. |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes voltage overshoot during clamping - preserves margin for 5 V tolerant interfaces such as CAN transceivers and ADC inputs. |
| Fast response time (<1 ps) | Activates before most semiconductor junctions fail - protects against ESD (IEC 61000-4-2 ±8 kV contact) and lightning-induced transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0AHE3/I | RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification; same VWM, VBR, and PPPM. | Approved for commercial-grade industrial controls but excluded from automotive Tier-1 BOMs requiring halogen-free + AEC-Q101. | Select when cost sensitivity outweighs automotive qualification and halogen-free requirements. |
| SMAJ6.0A-M3 | Lower PPPM (400 W vs. 600 W); SMA package (smaller footprint, higher RθJA = 140 °C/W); identical VWM/VBR. | Suitable for space-constrained consumer electronics with lower surge exposure; insufficient for IEC 61000-4-5 Level 4. | Choose only for compact designs with verified <400 W surge profiles and no automotive qualification needs. |
Compared with SMBJ6.0AHM3/I, the SMBJ6.0AHE3/I offers identical electrical specs but omits halogen-free and AEC-Q101 compliance, while the SMAJ6.0A-M3 reduces surge capacity by 33% and increases thermal resistance-making SMBJ6.0AHM3/I the sole option meeting full automotive and high-energy industrial surge standards.

FAQ
What is the maximum clamping voltage of the SMBJ6.0AHM3/I at its rated peak pulse current?
The SMBJ6.0AHM3/I clamps to a maximum of 10.3 V at its specified peak pulse current of 58.3 A (10/1000 µs waveform). This value is measured under standard test conditions with 0.2" × 0.2" copper pads per terminal and defines the upper voltage stress imposed on protected circuitry during worst-case surge events. The SMBJ6.0AHM3/I maintains this clamping performance across its full operating temperature range.
Is SMBJ6.0AHM3/I suitable for automotive applications requiring AEC-Q101 qualification?
Yes, SMBJ6.0AHM3/I is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in datasheet 88392. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD verification - making SMBJ6.0AHM3/I appropriate for under-hood and chassis-mounted automotive modules such as body control units and ADAS power domains.
How does the SMBJ6.0AHM3/I differ from the SMBJ6.0A-E3/I variant?
The SMBJ6.0AHM3/I uses halogen-free molding compound and carries AEC-Q101 qualification, whereas SMBJ6.0A-E3/I is RoHS-compliant but contains halogens and lacks automotive qualification. Both share identical electrical parameters (VWM = 6.0 V, VBR = 6.67–7.37 V, PPPM = 600 W), but SMBJ6.0AHM3/I meets stricter environmental and reliability requirements for Tier-1 automotive supply chains.
What is the thermal resistance junction-to-ambient for SMBJ6.0AHM3/I?
The SMBJ6.0AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended pad layout (0.2" × 0.2" copper pads per terminal). This value assumes still air conditions and directly impacts steady-state power dissipation limits - for example, at 50 °C ambient, the device can safely dissipate 5.0 W continuously, matching its rated PD.
Can SMBJ6.0AHM3/I be used in bidirectional transient protection circuits?
No, SMBJ6.0AHM3/I is a unidirectional TVS diode, indicated by its "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" suffix (e.g., SMBJ6.0CA). Using SMBJ6.0AHM3/I in bidirectional configurations risks forward conduction during negative transients and inadequate clamping - always verify polarity alignment and select SMBJ6.0AHM3/I only for DC-biased or single-polarity signal lines.
