Product details
Overview
1.5SMC130CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, designed for high-energy surge protection. It features a 130 V standoff voltage (VWM), 179 V maximum clamping voltage (VC) at 8.4 A peak pulse current (IPPM), and 1500 W peak pulse power capability with a 10/1000 μs waveform - ideal for safeguarding automotive sensor signal lines against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC130CAHM3/H datasheet, 1.5SMC130CAHM3/H pinout, 1.5SMC130CAHM3/H application, or 1.5SMC130CAHM3/H equivalent, this device serves as a halogen-free, RoHS-compliant, AEC-Q101-qualified TVS for automotive-grade ESD and surge immunity in CAN, LIN, and analog sensor interfaces where low clamping voltage and fast response (<1 ns) are critical.
Technical Context
The 1.5SMC130CAHM3/H operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±130 V in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 μA at VWM), while its thermal resistance (RθJL = 15 °C/W) supports reliable operation under repetitive transient stress up to 150 °C junction temperature.
Designed for automated SMT placement on standard 8.0 mm × 8.0 mm copper pads, it meets MSL Level 1 per J-STD-020 and withstands 260 °C lead-free reflow. The HM3 suffix confirms halogen-free, RoHS-compliant construction with AEC-Q101 qualification - validating suitability for automotive powertrain and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Tight tolerance ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 179 V at 8.4 A IPPM - Limits downstream voltage stress on protected ICs like microcontrollers or transceivers. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains high-energy transients (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure. |
| IPPM (Peak Pulse Current) | 8.4 A - Measured with 10/1000 μs waveform; determines surge current handling capacity. |
| TJ max. | 150 °C - Enables operation in under-hood environments with minimal derating. |
| Package | SMC (DO-214AB) - Industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height. |
Pinout & Package
Package: SMC (DO-214AB), bidirectional configuration - no polarity marking; symmetrical terminals function as anode and cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal conducts when voltage exceeds ±VBR; no fixed polarity - enables dual-direction surge suppression. |
| Terminal 2 | Anode/Cathode (bidirectional) | Paired terminal forms symmetrical clamping path; requires no orientation during PCB placement. |

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 | Lower peak power rating (600 W), same VWM/VC, SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a compliance | Select only for space-constrained non-automotive designs with verified lower surge exposure. |
| 1.5KE130CA | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly | Requires manual or wave soldering; not suitable for high-volume automated production | Choose only for legacy through-hole designs or prototyping where rework flexibility is prioritized over production efficiency. |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CAHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, 1500 W surge capability, and SMC package compatibility - making it the only option qualified for automotive SMT production requiring full ISO 7637-2 compliance.

FAQ
What is the clamping voltage of the 1.5SMC130CAHM3/H at its rated peak pulse current?
The 1.5SMC130CAHM3/H has a maximum clamping voltage (VC) of 179 V when subjected to its rated peak pulse current (IPPM) of 8.4 A with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC130CAHM3/H suitable for automotive applications?
Yes, the 1.5SMC130CAHM3/H is explicitly AEC-Q101 qualified (as indicated by the HM3 suffix) and designed for automotive use. It meets requirements for under-hood and body electronics, including CAN/LIN bus protection and sensor interface hardening. Its 150 °C maximum junction temperature, MSL Level 1 rating, and halogen-free construction align with automotive manufacturing and reliability standards.
Does the 1.5SMC130CAHM3/H have polarity markings?
No, the 1.5SMC130CAHM3/H is a bidirectional TVS diode and carries no polarity marking on the SMC (DO-214AB) package. Its symmetrical structure allows either terminal to serve as anode or cathode depending on transient polarity - simplifying PCB layout and eliminating orientation errors during automated placement.
What is the standoff voltage (VWM) and why is it important for the 1.5SMC130CAHM3/H?
The 1.5SMC130CAHM3/H has a standoff voltage (VWM) of 130 V, meaning it remains non-conductive up to this DC or RMS voltage level. This parameter ensures the device does not interfere with normal circuit operation - for example, in a 24 V automotive system with transient margins, VWM provides sufficient headroom to avoid false triggering while still engaging during surge events exceeding 130 V.
How does the 1.5SMC130CAHM3/H differ from unidirectional variants like 1.5SMC130AHM3/H?
The 1.5SMC130CAHM3/H is bidirectional (denoted by "CA"), providing symmetrical clamping for both positive and negative transients, whereas 1.5SMC130AHM3/H is unidirectional ("A") with a cathode band and clamps only in reverse bias. The CA version is used across differential lines (e.g., CAN, RS-485), while the "A" variant suits single-ended DC rails - making them functionally distinct, not interchangeable.
