Product details
Overview
1.5SMC130CAHM3/I 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), 1500 W peak pulse power (10/1000 μs), clamping voltage of 179 V at 8.4 A, and operates across -65 °C to +150 °C - used to protect automotive sensor signal lines, industrial I/O ports, and telecom interface circuits against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC130CAHM3/I datasheet, 1.5SMC130CAHM3/I pinout, 1.5SMC130CAHM3/I application, or 1.5SMC130CAHM3/I equivalent, this page delivers verified electrical parameters, thermal derating behavior, AEC-Q101 qualification status, bidirectional clamping performance, and real-world design implications for PCB-level transient suppression in harsh environments.
Technical Context
The 1.5SMC130CAHM3/I uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective clamping during sub-microsecond transients. Its bidirectional architecture provides symmetrical protection without polarity sensitivity, making it suitable for AC-coupled or differential signal paths.
Rated for 1500 W peak pulse power per 10/1000 μs waveform with 0.01% duty cycle, it sustains repetitive surges when mounted on 8.0 mm × 8.0 mm copper pads. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), supporting reliable operation under intermittent surge loads up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 111 V - maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold |
| VBR (Breakdown) | 124–137 V at 1 mA - guaranteed breakdown onset range; ensures predictable turn-on during overvoltage events |
| VC (Clamping) | 179 V at IPPM = 8.4 A - peak voltage seen by protected circuit during full-rated surge; determines stress on downstream components |
| PPPM | 1500 W - energy-handling capacity for 10/1000 μs transients; supports robust protection in automotive and industrial settings |
| ID (Leakage) | 1.0 μA max at VWM - negligible standby current; avoids loading sensitive analog or low-power signal paths |
| TJ max | +150 °C - enables use in under-hood automotive modules and high-temperature industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards |

Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Molding compound meets UL 94 V-0. No polarity marking - bidirectional operation confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (either direction) | Accepts surge current regardless of polarity; connects to line being protected |
| Cathode | Transient current exit point (either direction) | Completes low-impedance path to ground or return rail during clamping |

| Telecom Line Interface Protection | Consumer Power Adapter EMI Filtering |
Use Scenario: Shielding Ethernet PHY interfaces and DSL line drivers from lightning-induced surges entering via outdoor cabling in residential gateways. IC Role / Device Role / Timing Role: Bidirectional TVS connected across differential pairs (e.g., TX+/TX−) to suppress common-mode transients without distorting signal symmetry. Use Value: Maintains <1 ns response time and low capacitance to avoid degrading 100BASE-TX signal integrity while meeting ITU-T K.21 basic protection requirements. |
Use Scenario: Suppressing fast transients coupled into AC-DC adapter secondary-side outputs due to mains switching noise or nearby RF sources. IC Role / Device Role / Timing Role: Secondary-side TVS placed between DC output and ground to prevent overvoltage propagation to USB-C PD controllers or battery management ICs. Use Value: Clamps output overshoot to 179 V during 1500 W surges, protecting low-voltage logic rails and enabling compliance with IEC 62368-1 transient immunity clauses. |
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 PPPM (600 W), same VWM (111 V), SMB package (smaller footprint, higher RθJA = 85 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 without parallel devices | Select when board space is constrained and surge energy is ≤600 W; verify thermal margin with reduced copper area |
| 1.5KE130CA | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly and higher mounting inductance | Not viable for automated production or high-frequency transient suppression due to lead inductance (~15 nH vs. <2 nH for SMC) | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CAHM3/I delivers superior surge handling in an AEC-Q101-qualified SMT package, enabling direct integration into automotive and industrial PCBs without layout compromise or thermal derating penalties.

FAQ
What is the clamping voltage of the 1.5SMC130CAHM3/I at its rated peak pulse current?
The 1.5SMC130CAHM3/I has a maximum clamping voltage (VC) of 179 V at its rated peak pulse current (IPPM) of 8.4 A, measured using the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is critical for ensuring downstream ICs remain within their absolute maximum ratings. The 1.5SMC130CAHM3/I maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC130CAHM3/I suitable for automotive applications?
Yes, the 1.5SMC130CAHM3/I is AEC-Q101 qualified, as indicated by the "HM3" suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD validation per JESD22 standards. The 1.5SMC130CAHM3/I is routinely deployed in engine control units, ADAS camera modules, and body control modules where sustained reliability under thermal and electrical stress is mandatory.
How does the bidirectional configuration of the 1.5SMC130CAHM3/I affect its placement on the PCB?
The 1.5SMC130CAHM3/I has no polarity marking and functions identically in both directions, eliminating orientation constraints during automated placement. This simplifies layout for AC-coupled interfaces like RS-485, CAN FD, or Ethernet PHYs, where traditional unidirectional TVS diodes would require careful alignment. The 1.5SMC130CAHM3/I can be placed symmetrically across differential pairs or between any two nodes needing mutual transient suppression without concern for anode/cathode assignment.
What is the thermal resistance profile of the 1.5SMC130CAHM3/I, and how does it impact layout?
The 1.5SMC130CAHM3/I specifies RθJA = 75 °C/W (junction-to-ambient) and RθJL = 15 °C/W (junction-to-leads), assuming mounting on 8.0 mm × 8.0 mm copper pads per terminal. These values require minimum recommended pad geometry to achieve rated power dissipation - reducing copper area increases thermal impedance and risks exceeding TJ(max) = 150 °C during repetitive surges. The 1.5SMC130CAHM3/I datasheet provides derating curves showing allowable PPPM reduction above TA = 25 °C.
Does the 1.5SMC130CAHM3/I meet industry surge immunity standards such as IEC 61000-4-5?
The 1.5SMC130CAHM3/I's 1500 W peak pulse power rating aligns with IEC 61000-4-5 Level 4 (4 kV line-to-ground, 2 kV line-to-line) when implemented with proper PCB layout - including short traces, adequate ground plane coupling, and appropriate series impedance. While the device itself is not certified to the standard, its electrical characteristics enable compliant system-level design. The 1.5SMC130CAHM3/I is widely used in end-equipment that achieves full IEC 61000-4-5 certification when combined with matching filter networks and grounding strategies.
