Product details
Overview
SMBJ60AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed to protect sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBJ60AHM3_B/I datasheet, SMBJ60AHM3_B/I pinout, SMBJ60AHM3_B/I application, or SMBJ60AHM3_B/I equivalent, this device is selected for robust overvoltage protection in DC power rails, I/O interfaces, and automotive-grade sensor signal lines where low clamping voltage, fast response (<1 ns), and AEC-Q101 qualification are critical design requirements.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, leveraging a glass-passivated silicon junction to deliver precise reverse-breakdown behavior and stable clamping under repetitive surge conditions. Its thermal resistance (RθJA = 100 °C/W) and junction-to-lead resistance (RθJL = 20 °C/W) support reliable operation up to 150 °C junction temperature, with derating applied above 25 °C ambient.
The SMBJ60AHM3_B/I is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive applications. Its marking code "NK" identifies the 60 V variant, and polarity is indicated by a cathode band - essential for correct orientation in series-connected protection circuits on power inputs or bidirectional data lines with external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC rail protection threshold. |
| VBR min/max | 66.7 V / 73.7 V at IT = 1 mA - Ensures consistent avalanche initiation across production lots and temperature range. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamping voltage during 10/1000 µs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability; enables protection against high-energy transients per ISO 7637-2 Pulse 1/2/5a. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); supports inrush and fault-current tolerance in power supply inputs. |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood automotive environments and industrial enclosures. |
| Package | SMB (DO-214AA) - Standardized surface-mount footprint (5.21 mm × 4.06 mm) compatible with automated placement and reflow soldering. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case with matte tin-plated leads. Cathode identified by a single band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode | Avalanche breakdown terminal | Marked with band; connected to protected line (e.g., +12 V rail or signal input) to clamp positive transients to ground. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables compliance with IEC 61000-4-5 Level 4 (4 kV) and ISO 7637-2 Pulse 5a (75 V/300 ms) without derating. |

| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC J-STD-20 MSL level 1 - supports lead-free reflow and green manufacturing programs. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during surge events, protecting 65 V-rated MOSFETs and CAN transceivers without additional margin. |
| Fast response time & low dynamic impedance | Sub-nanosecond turn-on and <1 Ω incremental surge resistance ensure effective suppression before sensitive ICs experience overstress. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHE3_B/I | Same electrical specs, but RoHS-compliant commercial grade (not AEC-Q101 qualified); uses standard tin plating without halogen-free constraint. | Approved for industrial and consumer applications only; not certified for automotive under-hood deployment. | Select when AEC-Q101 is not required and cost optimization is prioritized over halogen-free compliance. |
| SMAJ60A-M3/A | Lower peak pulse power (400 W vs. 600 W); SMA package (smaller footprint, higher RθJA = 140 °C/W); same VWM/VC ratings. | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 Pulse 5a or lightning surge. | Choose only for space-constrained PCBs where surge energy is strictly limited and thermal margin is verified. |
Compared with SMBJ60AHM3_B/I, the HE3 variant lacks automotive qualification and halogen-free status, while the SMAJ60A-M3/A sacrifices 33 % pulse power headroom and thermal performance - making SMBJ60AHM3_B/I the sole choice for AEC-Q101-compliant, high-energy surge protection in compact SMB layout.

FAQ
What is the clamping voltage of SMBJ60AHM3_B/I at its rated peak pulse current?
The SMBJ60AHM3_B/I has a maximum clamping voltage (VC) of 96.8 V at its specified peak pulse current (IPPM) of 6.2 A, measured using the standardized 10/1000 µs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is confirmed in the Vishay datasheet Document Number 88392, page 2.
Is SMBJ60AHM3_B/I suitable for automotive applications?
Yes, SMBJ60AHM3_B/I is AEC-Q101 qualified and designated with the HM3 suffix, indicating halogen-free, RoHS-compliant construction validated for automotive use. It meets requirements for under-hood and chassis-mounted modules including engine control, body electronics, and ADAS sensor protection per ISO 7637-2 and ISO 16750-2 standards.
How does the SMBJ60AHM3_B/I differ from the SMBJ60A-E3/52 variant?
The SMBJ60AHM3_B/I differs from SMBJ60A-E3/52 in three key ways: it carries the HM3 suffix (halogen-free + RoHS), is AEC-Q101 qualified (vs. commercial-grade E3), and ships in 13-inch tape-and-reel (I-packaging code) versus 7-inch (52-code). Electrically and dimensionally, both share identical VWM, VBR, VC, and SMB package.
What is the polarity configuration of SMBJ60AHM3_B/I?
SMBJ60AHM3_B/I is a unidirectional TVS diode, with polarity defined by a cathode band on the package. The cathode must be connected to the line being protected (e.g., +12 V rail), and the anode to ground - enabling clamping only of positive-going transients while blocking reverse leakage below 1 µA at 60 V.
Can SMBJ60AHM3_B/I be used in bidirectional protection circuits?
No - SMBJ60AHM3_B/I is strictly unidirectional. For bidirectional protection, Vishay specifies the CA-suffix variants (e.g., SMBJ60CA). Using SMBJ60AHM3_B/I in a bidirectional configuration would expose the anode to reverse breakdown during negative transients, risking device failure and unprotected system behavior.
