Product details
Overview
SMBJ60CAHM3_A/H 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 signal or power lines. It features 60 V standoff 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 - used to protect MOSFETs, sensor interfaces, and industrial I/O circuits.
For engineers reviewing the SMBJ60CAHM3_A/H datasheet, SMBJ60CAHM3_A/H pinout, SMBJ60CAHM3_A/H application, or SMBJ60CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, halogen-free RoHS compliance, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche behavior in both polarities, enabling protection of AC-coupled or floating signal paths without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the 150 °C max junction temperature supports operation in harsh industrial and automotive environments.
The SMBJ60CAHM3_A/H delivers 600 W peak pulse power handling per 10/1000 µs waveform with 0.01% duty cycle, and exhibits fast response time (<1.0 ps) to transient events. Its incremental surge resistance is minimized to maintain low clamping voltage under high-current surges, supporting robust ESD and lightning-induced transient immunity in telecom and industrial control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V DC bus or ±48 V telecom line protection. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range ensures reliable triggering above VWM with controlled tolerance for design margining. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamping voltage during 10/1000 µs surge; limits downstream voltage stress to <100 V for 60 V-rated circuitry. |
| PPPM | 600 W - Peak pulse power dissipation capability enables suppression of high-energy transients such as ISO 7637-2 Pulse 1/2a/5a in automotive applications. |
| IPPM | 6.2 A - Peak pulse current corresponding to VC; determines minimum trace width and PCB copper area required for thermal management. |
| TJ max | +150 °C - Maximum junction temperature allows use in under-hood automotive modules or industrial enclosures without active cooling. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads; informs derating above 25 °C ambient. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, MSL Level 1 (260 °C reflow peak). Bidirectional construction has no polarity marking; terminals are symmetric anode/cathode pairs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (bidirectional) | Surge current path | Both terminals conduct identically during positive or negative transients; no cathode band marking; requires symmetric PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC signals, differential buses (e.g., RS-485), and floating sensors without polarity constraints or external diode pairing. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - suitable for body electronics and ADAS sensor interfaces. |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and JEDEC J-STD-020 MSL Level 1 requirements; compatible with lead-free reflow and green manufacturing programs. |
| 600 W 10/1000 µs rating | Supports IEC 61000-4-5 Level 4 (4 kV line-to-line) surge immunity when combined with appropriate series impedance. |
| Low leakage & tight VBR | <1.0 µA reverse leakage at 60 V and ±5.5% VBR tolerance reduce standby power loss and improve system-level voltage margining accuracy. |
Applications

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/H | Same electrical specs, but RoHS-compliant with brominated flame retardant (not halogen-free); lacks JESD201 Class 2 whisker resistance certification. | Suitable for commercial-grade industrial equipment where halogen-free requirement is not mandated by end-customer spec. | Select when cost sensitivity outweighs halogen-free compliance or automotive qualification needs. |
| SMAJ60CAHM3_A/H | Lower 400 W PPPM, higher VC (103 V), same VWM/VBR; SMA package (smaller footprint, higher RθJA = 140 °C/W). | Acceptable for lower-energy transients (e.g., IEC 61000-4-2 only) where board space is constrained and thermal budget permits. | Choose only if surge threat level is limited to ESD or low-duty-cycle switching noise, not lightning or load dump. |
Compared with SMBJ60CAHE3_A/H and SMAJ60CAHM3_A/H, the SMBJ60CAHM3_A/H uniquely combines halogen-free construction, AEC-Q101 qualification, and full 600 W surge capacity in SMB package - making it the preferred choice for automotive and green-industrial designs requiring highest reliability and regulatory alignment.

FAQ
What is the maximum clamping voltage of SMBJ60CAHM3_A/H at its rated peak pulse current?
The SMBJ60CAHM3_A/H has a maximum clamping voltage (VC) of 96.8 V at its specified peak pulse current (IPPM) of 6.2 A under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ60CAHM3_A/H maintains this clamping performance consistently across its qualified temperature range (-55 °C to +150 °C), ensuring predictable protection behavior in real-world deployments.
Is SMBJ60CAHM3_A/H suitable for automotive applications?
Yes, SMBJ60CAHM3_A/H is AEC-Q101 qualified and specifically designed for automotive use cases including body control modules, lighting drivers, and sensor interfaces. Its halogen-free, RoHS-compliant construction meets stringent automotive material requirements, and its 150 °C maximum junction temperature supports under-hood and cabin-mounted applications. The SMBJ60CAHM3_A/H also passes accelerated stress tests for temperature cycling, high-temperature reverse bias, and surge endurance - all documented in Vishay's AEC-Q101 certification report.
How does the bidirectional configuration of SMBJ60CAHM3_A/H affect its PCB layout?
The SMBJ60CAHM3_A/H has no polarity marking and identical electrical behavior in both directions, so PCB layout requires symmetric trace routing and equal copper pour area on both terminals to ensure balanced thermal dissipation and surge current sharing. Unlike unidirectional TVS diodes, no cathode band alignment is needed - simplifying automated placement and eliminating orientation errors. However, designers must still follow Vishay's recommended 0.2" × 0.2" copper pad layout per terminal to achieve the specified RθJA of 100 °C/W and full 600 W pulse rating.
What is the reverse leakage current specification for SMBJ60CAHM3_A/H at its standoff voltage?
At its 60 V standoff voltage (VWM), the SMBJ60CAHM3_A/H exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C ambient temperature. This low leakage minimizes standby power loss in battery-operated systems and avoids false triggering in high-impedance sensing circuits. Leakage remains below 5.0 µA up to 125 °C, supporting stable operation in thermally demanding environments without compromising signal integrity or power budget.
Does SMBJ60CAHM3_A/H meet any industry-standard surge immunity requirements out-of-the-box?
The SMBJ60CAHM3_A/H itself is a discrete component and does not "meet" system-level standards independently, but its 600 W 10/1000 µs rating and 96.8 V clamping voltage enable compliant designs for IEC 61000-4-5 Level 4 (4 kV line-to-line) and ISO 7637-2 Pulse 1/2a/5a when implemented with proper series impedance and PCB layout. Its AEC-Q101 qualification further validates suitability for automotive surge testing per ISO 16750-2. System-level compliance depends on full circuit implementation - the SMBJ60CAHM3_A/H provides the foundational clamping capability required to pass these tests.
