Product details
Overview
1.5SMC130C from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) in DO-214AB (SMC) package, with 117–143 V breakdown voltage (VBR), 105 V working stand-off voltage (VWM), and 187 V maximum clamping voltage (VC) at 8.4 A peak impulse current. It protects telecom power rails and industrial I/O interfaces against ESD and lightning-induced transients.
For engineers reviewing the 1.5SMC130C datasheet, 1.5SMC130C pinout, 1.5SMC130C application, or 1.5SMC130C equivalent, this page delivers verified electrical specs, thermal resistance (RθJA = 50 °C/W), ISO 7637-2 compliance, moisture sensitivity level 1, and bidirectional variant mapping - all critical for automotive and industrial surge protection design.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1.0 ps) and low leakage (<1 µA at VWM). Its unidirectional configuration provides asymmetric clamping-forward conduction only during reverse overvoltage events-making it suitable for DC-biased signal and power lines where polarity is fixed.
The device operates across –55 °C to +150 °C junction temperature range and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards. Thermal performance is defined by RθJC = 15 °C/W and RθJA = 50 °C/W, enabling reliable operation under sustained 6.5 W steady-state dissipation at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 117 V / 143 V - Ensures consistent breakdown initiation across production lots and temperature; guarantees clamping begins no later than 143 V under 1 mA test current. |
| VWM | 105 V - Maximum continuous DC or RMS operating voltage before leakage exceeds 1 µA; sets safe margin below system nominal 120 V DC rails. |
| VC @ IPPM | 187 V at 8.4 A - Clamping voltage during 10/1000 µs surge; limits downstream IC stress to <187 V during 1.5 kW transient events. |
| PPK | 1500 W - Peak pulse power rating per 1 ms waveform; supports immunity to ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b transients. |
| RθJA | 50 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area and airflow for thermal management at full power. |
| IR @ VWM | <1 µA - Ultra-low blocking leakage ensures minimal standby power loss and avoids false triggering in high-impedance sensing circuits. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, single-die unidirectional configuration. Cathode indicated by molded band on case. Matte tin-plated leads, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or lowest potential node; defines forward bias direction for clamping. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 120 V DC bus); conducts transient current to ground when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance (±5% for 'A' grade, ±10% standard) and long-term reliability under humidity and thermal cycling. |
| ISO 7637-2 compliance | Validated for automotive load-dump and switching transient immunity (Pulse 1/2a/2b/3a/3b), supporting 12 V and 24 V vehicle systems. |
| Moisture sensitivity level 1 | No floor-life limitation or bake requirement before reflow; compatible with standard SMT assembly without special handling. |
| Fast response time | <1.0 ps typical - Responds before most microsecond-scale transients fully develop, minimizing voltage overshoot on sensitive inputs. |
Applications
| Industrial PLC I/O Protection | Telecom Power Input Stage |
|---|---|
Use Scenario: Protecting 24 V DC digital input modules in programmable logic controllers from inductive kickback and field-wiring surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input terminal and ground, clamping transients before they reach optocoupler or MCU GPIO. Use Value: Limits voltage to ≤187 V during 1.5 kW surges, preserving isolation barrier integrity and preventing latch-up in downstream logic. |
Use Scenario: Safeguarding primary-side DC-DC converter inputs in telecom base station power supplies exposed to lightning-induced surges on -48 V distribution lines. IC Role / Device Role / Timing Role: Front-end transient suppressor mounted directly at connector entry point, shunting energy before bulk capacitors and controller ICs. Use Value: Withstands 8.4 A peak impulse current while maintaining VC ≤187 V, ensuring upstream fuse coordination and preventing brownout during surge recovery. |
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |
Use Scenario: Protecting LIN bus transceivers and power-switching FET gates in body electronics against battery dump and alternator load transients. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to chassis ground, absorbing reverse-polarity and load-dump energy on 12 V supply lines.

Use Scenario: Shielding 4–20 mA current loop receivers and analog front-ends in process automation transmitters from ESD and cable-coupled noise. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) TVS placed across loop input terminals to suppress fast transients without affecting precision current measurement. Use Value: Maintains signal accuracy by limiting leakage to sub-microamp level at 105 V, avoiding offset errors in µA-level sensing circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | 600 W rating, DO-214AA (SMB) package, VC = 219 V @ 4.2 A | Limited to lower-energy transients; smaller footprint but higher clamping voltage reduces protection margin. | Select when board space is constrained and peak surge energy is ≤600 W (e.g., non-automotive consumer I/O). |
| 1.5KE130C | Through-hole TO-204AA (DO-41), same VBR/VC, 1500 W rating | Requires wave soldering or hand assembly; unsuitable for high-density SMT-only production. | Choose for legacy designs, prototyping, or mixed-technology boards where SMT is not mandatory. |
Compared with SMBJ130A and 1.5KE130C, the 1.5SMC130C delivers identical 1500 W surge capability in a surface-mount DO-214AB package with lower clamping voltage (187 V vs. 219 V) and superior thermal resistance (50 °C/W vs. ~65 °C/W for SMB), making it optimal for automated, high-reliability industrial and automotive applications.

FAQ
What is the polarity configuration of the 1.5SMC130C?
The 1.5SMC130C is a unidirectional TVS diode, meaning it clamps only when reverse-biased - i.e., when cathode voltage exceeds anode voltage by ≥117 V. The cathode is marked by a molded band on the DO-214AB package. This configuration is ideal for protecting DC power lines with known polarity, such as 120 V DC telecom supplies. Unlike bidirectional variants (e.g., 1.5SMC130CA), the 1.5SMC130C does not conduct in forward bias beyond its low VF (~3.5 V), preserving normal circuit operation.
Does the 1.5SMC130C meet automotive transient immunity standards?
Yes, the 1.5SMC130C meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements for automotive electronic components. Its 1500 W peak pulse rating and 187 V clamping voltage at 8.4 A enable effective suppression of load-dump and inductive switching transients in 12 V and 24 V systems. While not AEC-Q101 qualified out-of-box, it is widely used in automotive body control and infotainment modules where design validation confirms compliance - always verify layout and grounding per ISO 11452-4 for full system-level immunity.
How does the 1.5SMC130C differ from the 'A' version (1.5SMC130A)?
The 1.5SMC130C has a standard VBR tolerance of ±10% (117–143 V), while the 1.5SMC130A offers tighter ±5% tolerance (124–137 V). Both share identical VWM (105 V), VC (187 V), PPK (1500 W), and package (DO-214AB). The 'C' suffix denotes the base commercial-grade variant; 'A' is preferred for precision voltage-margin applications like regulated 120 V DC systems where tighter clamping onset improves predictability. The 1.5SMC130C remains optimal for cost-sensitive, high-volume industrial use.
What is the maximum steady-state power dissipation for the 1.5SMC130C?
The 1.5SMC130C has a steady-state power dissipation (PD) rating of 6.5 W at TA = 25 °C, derated linearly above that ambient temperature per the pulse derating curve (Fig.2). This value reflects continuous DC power handling - not surge capability - and assumes adequate PCB copper area (≥1 in² thermal pad) and still-air conditions. In practice, the device sees negligible steady-state power under normal operation due to its <1 µA leakage at 105 V; the 6.5 W rating primarily supports fault-mode analysis and thermal design margining for worst-case scenarios.
Can the 1.5SMC130C be used in bidirectional signal lines?
No - the 1.5SMC130C is unidirectional and unsuitable for AC or bipolar signal lines. For bidirectional protection (e.g., RS-485, CAN, or audio lines), use the 1.5SMC130CA variant, which features symmetrical clamping in both directions and identical VBR, VC, and PPK ratings. Attempting to use the 1.5SMC130C on a bidirectional line would result in forward conduction during one half-cycle, potentially damaging the diode or distorting the signal. Always match TVS polarity and configuration to the protected circuit's voltage swing profile.
