Product details
Overview
SMBJ130CAHM3_B/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 130 V standoff voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 A peak pulse current (IPPM) under 10/1000 µs waveform, and clamps transients to ≤209 V at rated surge. It is used to protect MOSFETs, ICs, and sensor signal lines in industrial power supplies and telecom interfaces.
For engineers reviewing the SMBJ130CAHM3_B/I datasheet, SMBJ130CAHM3_B/I pinout, SMBJ130CAHM3_B/I application, or SMBJ130CAHM3_B/I equivalent, key selection considerations include bidirectional clamping capability, 600 W peak pulse power rating, AEC-Q101 qualification status, halogen-free RoHS compliance, and thermal resistance (RθJA = 100 °C/W) under standard PCB mounting conditions.
Technical Context
This TVS diode operates symmetrically in both directions, enabling suppression of positive and negative polarity transients without polarity-sensitive placement. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the low incremental surge resistance supports fast, predictable clamping response during ESD or lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and meets MSL level 1 per J-STD-020 with 260 °C reflow peak. Its SMB package provides mechanical robustness and compatibility with automated SMT assembly, and the HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101 qualified construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR (min/max) | 144 V / 159 V at IT = 1 mA - Confirmed breakdown threshold range; ensures reliable triggering above system operating voltage. |
| VC @ IPPM | 209 V - Clamping voltage at 209 A peak pulse (10/1000 µs); determines maximum stress imposed on downstream components. |
| PPPM | 600 W - Peak pulse power handling capacity; enables protection against high-energy transients like inductive switching spikes. |
| IPPM | 209 A - Maximum non-repetitive surge current; defines single-event energy absorption limit under standardized waveform. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; critical for thermal design margining. |
| TJ max. | 150 °C - Maximum allowable junction temperature; sets upper limit for ambient + self-heating in continuous operation. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H), matte tin-plated terminals, MSL Level 1, 260 °C reflow compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | One terminal of symmetrical junction; conducts during negative transients, enabling bidirectional clamping. |
| Cathode | Transient current entry (positive polarity) | Other terminal of symmetrical junction; conducts during positive transients; no band marking on bidirectional variants. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 600 W peak pulse power (10/1000 µs) | Supports high-energy surge immunity per IEC 61000-4-5 Level 4 (4 kV) when properly laid out. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock testing. |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for industrial and automotive end equipment without compromising performance. |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes voltage overshoot during clamping, reducing risk of damage to protected 130 V-rated components. |
Applications
| Industrial Motor Drives | Telecom Power Interfaces |
|---|---|
|

Use Value: Withstands 12 V system load dump pulses (ISO 7637-2 Pulse 5a) due to validated thermal and surge robustness. |
Use Scenario: Shielding analog outputs (e.g., 4–20 mA loops) and digital sensor interfaces (I²C, SPI) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS placed directly at connector or IC pad to minimize stub inductance. Use Value: Clamps sub-100 ns ESD events to <209 V while adding <10 pF parasitic capacitance, preserving signal integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CAHE3_B/I | Same electrical specs and SMB package; RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification. | Acceptable for commercial/industrial use where automotive qualification is not required. | Select when halogen-free content or automotive qualification is not mandated; lower cost alternative. |
| SMAJ130CAHM3_A | Lower power rating (400 W vs. 600 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Not suitable for high-energy surge environments; limited thermal margin in dense layouts. | Choose only for space-constrained designs with verified lower surge exposure and adequate cooling. |
Compared with SMBJ130CAHM3_B/I, the HE3 variant trades halogen-free content and AEC-Q101 qualification for cost savings in non-automotive settings, while the SMAJ130CAHM3_A reduces surge capability and thermal performance to fit smaller footprints-neither offers drop-in replacement without layout or reliability reassessment.

FAQ
What does the "CA" suffix indicate in SMBJ130CAHM3_B/I?
The "CA" suffix denotes a bidirectional configuration, meaning SMBJ130CAHM3_B/I clamps voltage transients of either polarity symmetrically. Unlike unidirectional variants (e.g., SMBJ130A), it has no cathode band marking and is used where AC signals, floating references, or polarity-agnostic protection are required-such as across differential bus lines or transformer-coupled interfaces.
Is SMBJ130CAHM3_B/I qualified for automotive applications?
Yes, SMBJ130CAHM3_B/I is AEC-Q101 qualified, as confirmed by the "HM3" suffix and Vishay documentation. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock-making SMBJ130CAHM3_B/I suitable for under-hood and body electronics where reliability under harsh conditions is mandatory.
What is the clamping voltage of SMBJ130CAHM3_B/I at its rated surge current?
The clamping voltage (VC) of SMBJ130CAHM3_B/I is 209 V at its peak pulse current (IPPM) of 209 A, measured under the standard 10/1000 µs waveform. This value represents the maximum voltage seen by protected circuitry during a full-rated surge event and is critical for ensuring downstream components remain within their absolute maximum ratings.
How does the HM3 suffix differ from E3 or HE3 in Vishay's SMBJ series?
The HM3 suffix in SMBJ130CAHM3_B/I indicates halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. In contrast, E3 is RoHS-compliant but not halogen-free or automotive-qualified; HE3 adds AEC-Q101 qualification but omits halogen-free content. Thus, SMBJ130CAHM3_B/I uniquely satisfies all three criteria-halogen-free, RoHS, and AEC-Q101-for stringent automotive and green-industry requirements.
Can SMBJ130CAHM3_B/I be used in place of a unidirectional TVS like SMBJ130A?
No-SMBJ130CAHM3_B/I is bidirectional and cannot replace unidirectional SMBJ130A in circuits requiring forward conduction or DC bias blocking, such as DC power rail protection with polarity-sensitive placement. Substituting SMBJ130CAHM3_B/I for SMBJ130A would allow reverse leakage path and may compromise protection integrity in polarized applications unless circuit topology explicitly supports symmetrical clamping.
