Product details
Overview
SMBJ60CAHM3/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 signal or power lines. It features a 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 against ESD and inductive switching surges.
For engineers reviewing the SMBJ60CAHM3/I datasheet, SMBJ60CAHM3/I pinout, SMBJ60CAHM3/I application, or SMBJ60CAHM3/I equivalent, this part serves as a halogen-free, RoHS-compliant, AEC-Q101 qualified TVS for automotive and industrial surge protection where bidirectional clamping, low leakage (<1 µA at VWM), and MSL Level 1 reflow compatibility are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of voltage polarity - critical for AC-coupled data lines or floating bus protection. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, while the 100 °C/W junction-to-ambient thermal resistance requires careful PCB copper pad design per Vishay's 0.2" × 0.2" (5.0 mm × 5.0 mm) recommendation for full 600 W rating.
The device meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 surge standards. With a 0.105 %/°C temperature coefficient of VBR, its breakdown voltage drift remains tightly controlled over -55 °C to +150 °C operating range - enabling reliable operation in under-hood automotive and factory-floor environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range ensuring predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage seen by protected circuit during 10/1000 µs surge; limits stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability with standard 10/1000 µs waveform; validates robustness against IEC 61000-4-5 surges. |

Pinout & Package
Package: SMB (DO-214AA), bidirectional configuration - no polarity marking; symmetrical terminals function as interchangeable anode/cathode pair depending on applied voltage polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode / Anode (Terminal 1) | Surge current entry/exit point | Either terminal conducts during positive or negative transients; bidirectional symmetry eliminates orientation constraints during placement. |
| Cathode / Anode (Terminal 2) | Surge current entry/exit point | Paired with Terminal 1 to form low-inductance clamping path; requires equal copper area (0.2" × 0.2") on both pads for rated 600 W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded power rails without polarity concerns. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV) surges when mounted per recommended pad layout - reduces need for cascaded protection stages. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Fulfills automotive and industrial environmental compliance mandates without compromising surge performance or thermal reliability. |
| AEC-Q101 qualified | Validated for automotive applications including body electronics and ADAS sensor interfaces where long-term reliability under thermal cycling is mandatory. |
| MSL Level 1 (260 °C peak) | Supports lead-free reflow soldering without moisture sensitivity limitations - eliminates bake requirements prior to assembly. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input 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 |
|---|---|---|---|
| SMBJ60CAHE3/I | RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification; same electrical specs and SMB package. | Suitable for commercial/industrial use where halogen-free or automotive qualification is not mandated. | Select when cost sensitivity outweighs halogen-free or automotive requirements. |
| SMCJ60CAHM3 | Larger SMC (DO-214AB) package; 1500 W PPPM; higher VC (103 V); same VWM/VBR range. | Used where higher surge energy absorption is needed, e.g., outdoor telecom equipment or solar inverter inputs. | Choose only if board space allows larger footprint and 1500 W rating is required - not drop-in compatible. |
Compared with SMBJ60CAHE3/I, the SMBJ60CAHM3/I adds halogen-free construction and AEC-Q101 qualification without sacrificing clamping performance; versus SMCJ60CAHM3, it trades surge capacity for compact SMB size - making it optimal for space-constrained automotive modules and industrial sensors requiring certified reliability.

FAQ
What is the maximum clamping voltage of SMBJ60CAHM3/I under a 10/1000 µs surge?
The SMBJ60CAHM3/I has a maximum clamping voltage (VC) of 96.8 V when subjected to its rated peak pulse current of 6.2 A with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings. The SMBJ60CAHM3/I achieves this clamping performance while maintaining low incremental surge resistance and fast response time.
Is SMBJ60CAHM3/I suitable for automotive applications?
Yes, SMBJ60CAHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction - meeting stringent automotive reliability and environmental requirements. It is specified for operation from -55 °C to +150 °C and validated for thermal cycling, mechanical shock, and humidity exposure per AEC-Q101. The SMBJ60CAHM3/I is commonly deployed in body control modules, sensor interfaces, and infotainment power rails where bidirectional transient suppression is required.
How does the bidirectional nature of SMBJ60CAHM3/I affect PCB layout?
The SMBJ60CAHM3/I has no polarity marking and functions identically in either direction, eliminating orientation constraints during placement - simplifying automated assembly and reducing risk of misorientation. However, both terminals must be routed with symmetrical, low-inductance paths and mounted on equal 0.2" × 0.2" copper pads to ensure balanced current sharing and full 600 W pulse power capability. Unlike unidirectional TVS diodes, the SMBJ60CAHM3/I does not require cathode alignment relative to ground or signal reference.
What is the reverse leakage current of SMBJ60CAHM3/I at its standoff voltage?
At its 60 V standoff voltage (VWM), the SMBJ60CAHM3/I exhibits a maximum reverse leakage current (ID) of 1 µA at 25 °C - verified per Vishay's electrical characteristics table. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes standby power loss in battery-operated systems. Leakage remains below 5 µA up to 125 °C, supporting stable performance across extended temperature ranges without compromising protected circuit functionality.
Can SMBJ60CAHM3/I replace SMBJ60A in existing designs?
No - SMBJ60CAHM3/I is bidirectional, whereas SMBJ60A is unidirectional and features a cathode band for polarity identification. Substituting SMBJ60CAHM3/I for SMBJ60A would eliminate polarity dependency but may alter clamping behavior in DC-biased circuits, especially where forward conduction matters. The SMBJ60CAHM3/I has identical VWM, VBR, and PPPM ratings, but its symmetrical I-V curve means it conducts on both polarities - requiring verification of system-level surge path and grounding architecture before replacement.
