Product details
Overview
SMBJ60CAHM3_B/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 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), 96.8 V maximum clamping voltage (VC) at 6.2 A, and operates across –55 °C to +150 °C junction temperature range - deployed in industrial sensor interface protection.
For engineers reviewing the SMBJ60CAHM3_B/I datasheet, SMBJ60CAHM3_B/I pinout, SMBJ60CAHM3_B/I application, or SMBJ60CAHM3_B/I equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker testing.
Technical Context
This device functions as a bidirectional avalanche diode with symmetrical reverse/forward conduction, enabling transient suppression on AC-coupled or differential signal lines without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, critical for consistent clamping under repetitive ESD or lightning-induced surges.
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads, it delivers 600 W peak pulse power handling with 10/1000 µs waveform and meets MSL Level 1 (260 °C reflow peak). The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction - validated for automotive body electronics and industrial control modules.
Key Specifications

|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V DC systems. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed bidirectional breakdown window; ensures reliable triggering above system overvoltage thresholds. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage during 600 W transient; limits downstream IC stress to <100 V in 48 V bus protection. |
| PPPM | 600 W - Peak pulse power rating (10/1000 µs); supports IEC 61000-4-5 Level 3 (1 kV/42 Ω) surge immunity. |
| TJ max. | +150 °C - Maximum junction temperature; enables deployment in engine bay or industrial enclosures without derating. |
| RθJA | 100 °C/W - Thermal resistance junction-to-ambient on standard PCB pad; informs heatsinking requirements for sustained surge duty. |
| Leakage @ VWM | 1.0 µA max - Ultra-low reverse leakage preserves signal integrity and battery life in always-on sensor nodes. |

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_B/I | Same electrical specs and SMB package; RoHS-compliant but not halogen-free (E3 vs HM3). | Lacks halogen-free certification; acceptable for commercial-grade industrial designs where material compliance is less stringent. | Select when halogen-free requirement is waived and cost optimization is prioritized over automotive-grade material specs. |
| SMAJ60CAHM3_A/I | Lower 400 W PPPM, SMA (DO-214AC) package (smaller footprint, higher RθJA = 140 °C/W). | Reduced surge handling; suited for space-constrained consumer ports rather than industrial power rails. | Choose only if board area is critical and surge threat level is limited to IEC 61000-4-2 ESD, not full IEC 61000-4-5 surges. |
Compared with SMBJ60CAHE3_B/I, the SMBJ60CAHM3_B/I adds halogen-free compliance and AEC-Q101 qualification without sacrificing clamping performance; versus SMAJ60CAHM3_A/I, it provides 50% higher surge power and superior thermal dissipation - making it the preferred choice for automotive and industrial 48 V system protection.

FAQ
What is the clamping voltage of SMBJ60CAHM3_B/I at its rated peak pulse current?
The SMBJ60CAHM3_B/I has a maximum clamping voltage (VC) of 96.8 V at its peak pulse current (IPPM) of 6.2 A, measured under the standardized 10/1000 µs waveform. This value is confirmed in the Vishay datasheet (Document Number: 88392, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The SMBJ60CAHM3_B/I maintains this clamping performance across its full operating temperature range.
Is SMBJ60CAHM3_B/I suitable for automotive applications?
Yes, SMBJ60CAHM3_B/I is AEC-Q101 qualified, as indicated by the "HM3" suffix in its ordering code - confirming validation for automotive use cases including body electronics, infotainment interfaces, and sensor harnesses. Its –55 °C to +150 °C operating junction temperature range, halogen-free construction, and MSL Level 1 reflow compatibility meet key automotive manufacturing and reliability requirements. The SMBJ60CAHM3_B/I is explicitly listed in Vishay's AEC-Q101 qualified product table.
How does SMBJ60CAHM3_B/I differ from unidirectional SMBJ60A variants?
The SMBJ60CAHM3_B/I is bidirectional, meaning it clamps voltage transients in both polarities - essential for AC-coupled or differential signal lines like RS-485 or LIN bus. In contrast, unidirectional SMBJ60A types conduct only in reverse bias and require correct cathode orientation. Electrical differences include identical VWM (60 V) and VBR range, but SMBJ60CAHM3_B/I exhibits symmetrical I-V characteristics and lacks polarity marking, whereas SMBJ60A uses a band to denote cathode. Both share the same SMB package and 600 W PPPM.
What is the thermal resistance of SMBJ60CAHM3_B/I, and how does it affect layout?
The SMBJ60CAHM3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's outline drawing. To maintain safe junction temperatures during repetitive surges, designers must ensure adequate copper area and avoid excessive trace length or isolation. For high-duty-cycle applications, adding thermal vias under the pads reduces effective RθJA - a practice validated in Vishay's thermal characterization curves (Fig. 5).
Does SMBJ60CAHM3_B/I meet RoHS and halogen-free requirements?
Yes, SMBJ60CAHM3_B/I is halogen-free and RoHS-compliant, as confirmed by the "HM3" suffix in its part number - denoting halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. It satisfies JEDEC JESD201 Class 2 whisker resistance and UL 94 V-0 flammability rating for molding compound. Material compliance aligns with Vishay document 99912, and the device carries full traceability for environmental reporting. No exemptions or declarations are required for standard compliance use cases.
