Product details
Overview
SMBJ130CAHM3/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 power and signal lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 A peak pulse current (IPPM), 209 V clamping voltage (VC) at IPPM, and 600 W peak pulse power (10/1000 µs waveform), used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ130CAHM3/H datasheet, SMBJ130CAHM3/H pinout, SMBJ130CAHM3/H application, or SMBJ130CAHM3/H equivalent, key selection criteria include bidirectional transient suppression capability, clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both directions, enabling robust protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the low incremental surge resistance supports fast energy diversion during ESD or lightning-induced transients.
The SMBJ130CAHM3/H is rated for TJ = –55 °C to +150 °C operation and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its 20 °C/W junction-to-lead thermal resistance enables effective heat transfer to PCB copper pads, and its 0.106 g unit weight aligns with automated SMT placement requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 120 VAC-derived rails or 110 VDC systems. |

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/H | Same electrical specs, but RoHS-compliant commercial grade (not halogen-free); lacks AEC-Q101 qualification. | Suitable for non-automotive industrial equipment where halogen-free mandate or automotive qualification is not required. | Select when cost sensitivity outweighs halogen-free or automotive qualification needs; identical footprint and soldering profile. |
| SMAJ130CAHM3 | Lower PPPM (400 W vs. 600 W); same VWM/VBR/VC; SMA package (smaller, higher RθJA = 140 °C/W). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for IEC 61000-4-5 surge due to reduced power rating. | Choose only for space-constrained designs with verified sub-400 W surge exposure; requires thermal redesign due to higher junction temperature rise. |
Compared with SMBJ130CAHE3/H, the SMBJ130CAHM3/H adds halogen-free construction and AEC-Q101 qualification without sacrificing clamping performance; versus SMAJ130CAHM3, it delivers 50 % higher surge power handling and superior thermal dissipation in the larger SMB package.

FAQ
What does the "CA" suffix indicate in SMBJ130CAHM3/H?
The "CA" suffix in SMBJ130CAHM3/H denotes a bidirectional Transient Voltage Suppressor configuration, meaning the device provides symmetrical clamping in both polarities-ideal for protecting AC lines, differential buses like RS-485, or floating sensor inputs without requiring polarity-aware layout. This differs from unidirectional "A" variants that require correct cathode orientation relative to circuit ground.
Is SMBJ130CAHM3/H qualified for automotive applications?
Yes, SMBJ130CAHM3/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix (halogen-free, RoHS-compliant, and AEC-Q101 qualified). This qualification covers stress tests including temperature cycling, humidity, mechanical shock, and high-temperature operating life-making it suitable for under-hood and body electronics in passenger vehicles and commercial vehicles.
What is the maximum clamping voltage of SMBJ130CAHM3/H under surge conditions?
The maximum clamping voltage (VC) of SMBJ130CAHM3/H is 209 V, measured at its rated peak pulse current (IPPM) of 209 A using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is critical for ensuring downstream components remain within their absolute maximum ratings.
How does the SMB package of SMBJ130CAHM3/H compare to SMA in thermal performance?
The SMB (DO-214AA) package of SMBJ130CAHM3/H offers significantly better thermal performance than the smaller SMA package: its typical junction-to-ambient thermal resistance (RθJA) is 100 °C/W versus ~140 °C/W for SMA, and its junction-to-lead resistance (RθJL) is 20 °C/W. This allows SMBJ130CAHM3/H to sustain higher surge duty cycles and operate reliably in compact, high-power-density layouts without additional heatsinking.
Does SMBJ130CAHM3/H require special PCB layout considerations?
Yes-optimal performance of SMBJ130CAHM3/H requires mounting on minimum recommended copper pad areas (0.2" × 0.2" / 5.0 mm × 5.0 mm per terminal) to achieve specified thermal and surge ratings. Reduced pad size increases RθJA and lowers IPPM derating; additionally, short, low-inductance traces to ground or return paths are essential to minimize voltage overshoot during fast transients.
