Product details
Overview
SMBJ60CAHM3_A/I from Vishay General Semiconductor is a bidirectional 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 standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤96.8 V at 6.2 A peak surge current - deployed in industrial sensor interfaces and automotive control modules.
For engineers reviewing the SMBJ60CAHM3_A/I datasheet, SMBJ60CAHM3_A/I pinout, SMBJ60CAHM3_A/I application, or SMBJ60CAHM3_A/I equivalent, this device is selected for robust ESD and lightning surge protection where bidirectional clamping, low clamping ratio (VC/VBR ≈ 1.45), and AEC-Q101 qualification for automotive-grade reliability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (66.7 V / 73.7 V), VC = 96.8 V at IPPM = 6.2 A, and ID ≤ 1.0 µA at VWM = 60 V. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
The device uses a planar junction structure in an SMB package with matte tin-plated leads, rated for TJ = –55 °C to +150 °C and capable of handling 100 A non-repetitive forward surge (IFSM) in unidirectional mode - though SMBJ60CAHM3_A/I is bidirectional and thus does not conduct steady forward current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping begins; defines safe working range for 48 V DC systems. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - tight breakdown window ensures predictable turn-on during transients. |
| VC @ IPPM | 96.8 V at 6.2 A (10/1000 µs) - clamping voltage limits downstream IC stress to <100 V under standard surge test. |
| PPPM | 600 W - peak transient energy absorption capability compatible with IEC 61000-4-5 Level 4 surge testing. |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves signal integrity and battery life in always-on sensor circuits. |
| TJ max | +150 °C - enables operation in under-hood automotive environments and high-ambient industrial enclosures. |
| Package | SMB (DO-214AA) - 0.220" × 0.155" footprint with 0.086" cathode band width; compatible with automated SMT placement. |
Pinout & Package
Two-terminal bidirectional device in SMB (DO-214AA) package; no polarity marking - symmetrical terminals function identically as anode/cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Transient input/output node | Connects to protected line (e.g., CAN_H or RS-485 A); conducts during either positive or negative overvoltage event. |
| Terminal 2 | Transient input/output node | Connects to reference plane (GND or complementary line); completes bidirectional clamping path with Terminal 1. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CAHE3_A/I | Same electrical specs; RoHS-compliant but not halogen-free; lacks HM3 suffix. | Approved for commercial-grade automotive modules where halogen-free is not mandated. | Select when cost sensitivity outweighs halogen-free requirement and AEC-Q101 qualification is retained. |
| SMAJ60CAHM3_A/I | Lower PPPM (400 W vs. 600 W); same VWM/VBR/VC; SMA package (smaller, lower thermal mass). | Suitable for space-constrained consumer PCBs with lower surge threat levels (e.g., IEC 61000-4-5 Level 2). | Choose for compact designs where 400 W surge margin suffices and thermal derating above 70 °C is acceptable. |
Compared with SMBJ60CAHE3_A/I and SMAJ60CAHM3_A/I, SMBJ60CAHM3_A/I delivers higher surge robustness in a thermally superior SMB package while meeting halogen-free and AEC-Q101 requirements - making it optimal for mission-critical automotive and industrial deployments demanding full 600 W immunity.

FAQ
What is the clamping voltage of SMBJ60CAHM3_A/I at its rated peak pulse current?
The SMBJ60CAHM3_A/I clamps to a maximum of 96.8 V at its specified peak pulse current of 6.2 A under the 10/1000 µs waveform condition. This value is measured per JEDEC standards and reflects worst-case voltage seen by downstream circuitry during surge events - a key parameter for ensuring protected ICs remain within absolute maximum ratings. The SMBJ60CAHM3_A/I achieves this with low dynamic impedance and stable junction characteristics.
Is SMBJ60CAHM3_A/I suitable for automotive applications?
Yes, SMBJ60CAHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction validated for automotive use. It meets stress test requirements for temperature cycling, humidity, and mechanical shock applicable to engine control, body electronics, and ADAS sensor modules. The SMBJ60CAHM3_A/I operates reliably from –55 °C to +150 °C junction temperature, supporting under-hood deployment.
How does the bidirectional design of SMBJ60CAHM3_A/I benefit differential interface protection?
The bidirectional architecture of SMBJ60CAHM3_A/I allows symmetric clamping on both polarities without requiring external polarity configuration - ideal for protecting differential buses like CAN, RS-485, or LVDS where transients may appear as common-mode spikes. Unlike unidirectional TVS diodes, SMBJ60CAHM3_A/I eliminates the need for dual devices or complex layout routing, reducing BOM count and PCB area while ensuring consistent protection across signal pairs.
What is the maximum leakage current of SMBJ60CAHM3_A/I at its standoff voltage?
At its 60 V standoff voltage (VWM), SMBJ60CAHM3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C - verified per datasheet test conditions. This ultra-low leakage preserves power efficiency in battery-operated sensor nodes and avoids false triggering in high-impedance monitoring circuits. The SMBJ60CAHM3_A/I maintains this specification across its full operating temperature range with minimal drift.
Does SMBJ60CAHM3_A/I require special PCB layout considerations?
Yes - for optimal surge performance, SMBJ60CAHM3_A/I should be mounted using the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal to ensure adequate thermal dissipation and low-inductance paths. Short, direct traces to protected line and ground minimize parasitic inductance that could elevate clamping voltage during fast transients. The SMBJ60CAHM3_A/I's SMB package supports standard SMT reflow profiles without special handling beyond MSL Level 1 compliance.
