Overview
1.5SMC130CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 130 V standoff voltage (VWM), 179 V clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5SMC130CAHM3_A/H datasheet, 1.5SMC130CAHM3_A/H pinout, 1.5SMC130CAHM3_A/H application, or 1.5SMC130CAHM3_A/H equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS offers verified bidirectional clamping performance, MSL Level 1 moisture sensitivity, and DO-214AB (SMC) package compatibility for high-reliability board-level surge suppression.
Technical Context
The 1.5SMC130CAHM3_A/H operates as a bidirectional avalanche diode, symmetrically clamping transient voltages above ±179 V while maintaining ≤1.0 μA leakage at 130 V reverse standoff. Its glass-passivated junction ensures stable breakdown behavior and fast response (<1 ns) to ESD and lightning-induced surges.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it delivers 1500 W peak pulse power handling with 0.01% duty cycle, derated linearly above 25 °C ambient per Fig. 2, and supports operating junction temperatures from –65 °C to +150 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Same VWM (130 V) and VC (179 V), but lower PPPM (600 W); SMB package (smaller footprint, higher thermal resistance). | Limited to lower-energy surges (e.g., IEC 61000-4-2 only); unsuitable for IEC 61000-4-5 Level 3+ or automotive load dump. | Select when board space is constrained and surge threat level is limited to ESD and low-energy switching noise. |
| 1.5KE130CA | Same electrical specs, but axial-leaded DO-201 package; higher RθJA (~50 °C/W vs. 75 °C/W for SMC), manual assembly only. | Not suitable for automated SMT lines; requires through-hole routing and wave soldering; incompatible with high-density layouts. | Choose only for legacy repair, prototyping, or low-volume non-automated builds where reflow compatibility is not required. |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CAHM3_A/H uniquely combines AEC-Q101 qualification, 1500 W surge capacity, SMC surface-mount compatibility, and halogen-free construction - making it the only option qualified for volume automotive and industrial SMT production requiring full IEC 61000-4-5 compliance.

FAQ
What is the clamping voltage of the 1.5SMC130CAHM3_A/H under a standard 10/1000 μs surge?
The 1.5SMC130CAHM3_A/H has a maximum clamping voltage (VC) of 179 V at 8.4 A peak pulse current with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and represents the upper limit of voltage imposed on the protected circuit during a standardized surge event - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the 1.5SMC130CAHM3_A/H suitable for automotive applications?
Yes, the 1.5SMC130CAHM3_A/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It is explicitly rated for under-hood and chassis-mounted use with guaranteed performance across –65 °C to +150 °C junction temperature and validated against temperature cycling, HTRB, and surge endurance per AEC-Q101 test plan - making it appropriate for engine control units, ADAS sensors, and body electronics using the 1.5SMC130CAHM3_A/H.
Does the 1.5SMC130CAHM3_A/H require polarity-aware PCB layout?
No, the 1.5SMC130CAHM3_A/H is a bidirectional TVS diode with symmetrical terminals and no polarity marking. Both leads function identically regardless of voltage polarity, allowing unrestricted orientation during placement. This eliminates orientation errors in automated assembly and simplifies PCB design - unlike unidirectional variants such as 1.5SMC130AHM3_A/H, which require cathode-band alignment.
What is the thermal resistance of the 1.5SMC130CAHM3_A/H in typical mounting conditions?
The 1.5SMC130CAHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB with no internal planes; adding thermal vias or ground planes can reduce effective RθJA, but the 75 °C/W baseline must be used for worst-case thermal design margining of the 1.5SMC130CAHM3_A/H.
How does the 1.5SMC130CAHM3_A/H compare to the 1.5SMC130A variant?
The 1.5SMC130CAHM3_A/H is the bidirectional version (denoted by "CA") with halogen-free, AEC-Q101 qualified construction (HM3), whereas 1.5SMC130A is unidirectional and commercial-grade (E3/M3). Electrically, the 1.5SMC130CAHM3_A/H clamps equally in both directions (VWM = 130 V, VC = 179 V), while 1.5SMC130A only protects in reverse bias and conducts forward current - making the 1.5SMC130CAHM3_A/H mandatory for AC-coupled or floating signal lines where polarity reversal occurs.
