Product details
Overview
SMBJ60AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), 6.2 A peak pulse current (IPPM), and 96.8 V maximum clamping voltage (VC) - deployed in industrial motor drives to protect MOSFET gate drivers from inductive switching surges.
For engineers reviewing the SMBJ60AHM3_B/H datasheet, SMBJ60AHM3_B/H pinout, SMBJ60AHM3_B/H application, or SMBJ60AHM3_B/H equivalent, this page delivers verified electrical parameters, thermal behavior under surge conditions, AEC-Q101 qualification status, halogen-free RoHS compliance, and real-world protection use cases - all aligned with Vishay Document #88392 (Rev. 09-Jan-2024).
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation, it remains high-impedance until transient voltage exceeds VBR, then avalanches to limit voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (≤1.0 µA at VWM = 60 V).
Thermal design relies on RθJA = 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W (junction-to-lead), enabling reliable energy dissipation of repetitive 600 W pulses at ≤0.01% duty cycle. The device is rated for TJ = –55 to +150 °C and meets MSL Level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working range for protected line. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - guaranteed avalanche onset window; ensures predictable turn-on margin above VWM. |
| VC @ IPPM | 96.8 V at IPPM = 6.2 A (10/1000 µs) - clamped voltage seen by downstream ICs during worst-case surge; limits stress on 100 V-rated components. |
| PPPM | 600 W - peak transient power handled without failure; validated per IEC 61000-4-5 waveform standards. |
| ID @ VWM | ≤1.0 µA - ultra-low reverse leakage at rated stand-off; prevents measurable power loss or bias shift in high-impedance sensor interfaces. |
| TJ max. | +150 °C - maximum junction temperature; supports operation in under-hood automotive and industrial enclosures without derating. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place and reflow profiles up to 260 °C peak. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads. Cathode indicated by band marking on cathode end; anode is unmarked end. Meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line (e.g., VDD rail); conducts surge current to ground when voltage exceeds VBR. |
| Anode (unbanded end) | Reference/return path | Typically tied to system ground or low-impedance return plane; completes clamping loop during transient event. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Handles high-energy transients from relay coil de-energization or ESD events without degradation over 1000+ cycles. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - suitable for ADAS power modules. |
| Halogen-free & RoHS-compliant (HM3) | Meets IPC-1752A material declaration requirements and EU Directive 2011/65/EU; no brominated flame retardants in molding compound. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage overshoot during clamping - critical for protecting 65 V logic-level MOSFETs in BLDC motor controllers. |
| MSL Level 1 (260 °C peak) | Allows single-reflow assembly without moisture sensitivity concerns; eliminates bake-out requirement in production SMT lines. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHE3_B/H | Same VWM, VBR, VC, and PPPM; RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification. | Approved for commercial/industrial use only; excluded from automotive Tier-1 BOMs requiring halogen-free and AEC-Q101 compliance. | Select when cost sensitivity outweighs automotive qualification and halogen-free requirements. |
| SMCJ60A-HF | Same VWM (60 V) and VC (96.8 V), but SMC (DO-214AB) package - 7.11 mm × 6.22 mm footprint, 2× higher thermal mass, RθJA = 50 °C/W. | Better suited for high-repetition-rate surges (>1 Hz) due to superior heat dissipation; requires larger PCB area and different pad layout. | Choose when thermal management dominates over board space constraints, e.g., in high-power UPS systems. |
Compared with SMBJ60AHE3_B/H, SMBJ60AHM3_B/H adds halogen-free construction and AEC-Q101 qualification without sacrificing electrical specs - making it the preferred choice for automotive and green-industry designs. Against SMCJ60A-HF, it trades thermal robustness for compactness and lower assembly cost in space-constrained applications.

FAQ
What is the maximum clamping voltage of SMBJ60AHM3_B/H under a 10/1000 µs surge?
The SMBJ60AHM3_B/H has a maximum clamping voltage (VC) of 96.8 V when subjected to its rated peak pulse current (IPPM = 6.2 A) using the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay Document #88392 and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events. The SMBJ60AHM3_B/H maintains this clamping performance across its full operating temperature range (–55 °C to +150 °C).
Is SMBJ60AHM3_B/H qualified for automotive applications?
Yes, SMBJ60AHM3_B/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and explicit note in the Vishay datasheet (Document #88392, page 3). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and surge endurance - validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS power stages.
How does the halogen-free status of SMBJ60AHM3_B/H impact PCB assembly?
The halogen-free status of SMBJ60AHM3_B/H means its molding compound contains no chlorine or bromine-based flame retardants, complying with IPC-1752A and JEDEC JS709E standards. During reflow, it behaves identically to standard SMB packages - supporting peak temperatures up to 260 °C (MSL Level 1) without delamination or solder joint defects. No process adjustments are required versus non-halogen-free variants like SMBJ60AHE3_B/H.
What is the reverse leakage current of SMBJ60AHM3_B/H at its rated stand-off voltage?
At VWM = 60 V and TA = 25 °C, the SMBJ60AHM3_B/H exhibits a maximum reverse leakage current (ID) of 1.0 µA. This ultra-low leakage ensures minimal power loss in always-on monitoring circuits and avoids loading errors in high-impedance sensor front-ends. Leakage remains ≤5.0 µA up to TJ = 125 °C, as verified in Vishay's thermal derating curves (Figure 2).
Can SMBJ60AHM3_B/H be used in bidirectional protection configurations?
No, SMBJ60AHM3_B/H is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., SMBJ60CA). Using SMBJ60AHM3_B/H in bidirectional applications would leave positive-going transients unprotected - potentially damaging downstream components. For symmetric surge protection, select SMBJ60CA-HM3 or equivalent.
