Product details
Overview
1.5SMC130CA from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It delivers 1500W peak pulse power, 124V–137V breakdown voltage (VBR), 111V working stand-off voltage (VWM), and clamps transients to ≤179V at 8.7A peak impulse current - deployed in telecom power rails, industrial I/O ports, and automotive body control modules.
For engineers reviewing the 1.5SMC130CA datasheet, 1.5SMC130CA pinout, 1.5SMC130CA application, or 1.5SMC130CA equivalent, key selection criteria include bidirectional clamping capability, DO-214AB package thermal performance (RθJA = 50°C/W), compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b, and low leakage (<1µA @ 111V).
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (>1MΩ), then avalanches rapidly (<1.0ps response) when transient voltage exceeds VBR, diverting surge current away from downstream circuitry. Its bidirectional symmetry enables protection of AC-coupled or floating signal paths without polarity constraints.
Thermally, the device uses a glass-passivated junction in a DO-214AB (SMC) package with RθJC = 15°C/W and maximum junction temperature of +150°C - enabling reliable operation in ambient temperatures up to +125°C after derating per Fig.2. Moisture sensitivity level is J-STD-020 Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V / 137 V - defines guaranteed avalanche onset range at 1mA test current; ensures consistent clamping across production lots |
| VWM | 111 V - maximum continuous reverse operating voltage; sets safe DC bias margin before leakage rises sharply |
| VC @ IPPM | ≤179 V at 8.7 A - clamping voltage during 10/1000µs surge; determines protected circuit's maximum transient exposure |
| PPK | 1500 W - peak pulse power handling per single 10/1000µs waveform; supports IEC 61000-4-5 Level 4 surges |
| IR @ VWM | <1 µA - ultra-low blocking leakage; avoids power loss or false triggering in high-impedance monitoring circuits |
| TJ max | +150 °C - maximum junction temperature; allows use in under-hood automotive or enclosed industrial enclosures |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline; compatible with automated pick-and-place and reflow profiles |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, cathode band marking for unidirectional variants (not applicable to 1.5SMC130CA due to bidirectional symmetry). Polarity is non-directional; both terminals are electrically identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as reference; no polarity dependency - simplifies PCB layout and eliminates orientation errors |
| Case | Non-connected thermal mass | Plastic body provides mechanical robustness and thermal conduction path to PCB copper; no electrical connection |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both directions - protects AC signals, differential buses, and floating grounds without external diode pairing |
| ISO 7637-2 compliance | Validated against Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line capacitance discharge) - meets automotive ECU immunity requirements |
| Fast response time | <1.0 ps junction response - engages before most microsecond-scale transients can damage CMOS inputs or analog front-ends |
| Low moisture sensitivity | J-STD-020 Level 1 rating - zero floor life limitation; no baking required prior to reflow assembly |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - suitable for green manufacturing and export-regulated markets |
Applications
| Telecom Power Input Protection | Industrial PLC Analog I/O |
|---|---|

Use Value: Maintains signal integrity by limiting excursion beyond ±179V while adding <1pF junction capacitance - no bandwidth degradation in 100kHz sensor loops. |
| Automotive Body Control Module | USB-C Port ESD Protection |
Use Scenario: Suppressing load-dump pulses (ISO 7637-2 Pulse 5a) on 12V supply lines feeding BCM microcontrollers and CAN transceivers. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power rail, coordinated with downstream ceramic capacitors for energy absorption. Use Value: Withstands 1500W peak power for 40ms duration per ISO 7637-2, enabling compliance without parallel TVS stacking or oversized heatsinking. | Use Scenario: Providing secondary-level surge immunity on USB-C CC and VBUS lines subjected to hot-plug and cable coupling events. IC Role / Device Role / Timing Role: High-power backup protector behind primary ESD array (e.g., 1.5KE series), handling multi-pulse stress. Use Value: Delivers 1500W clamping at 111V working voltage - higher standoff than standard 5V TVS, avoiding false triggering during 20V PD negotiation. |
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 | 600W peak power (vs. 1500W); same VBR range and DO-214AA package | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for ISO 7637-2 Pulse 5a | Select when space-constrained layouts require smaller SMB footprint and surge threat level is moderate |
| 1.5KE130CA | Through-hole DO-15 package; identical 1500W rating and VBR/VC specs | Requires wave soldering or hand assembly; incompatible with fully SMT production lines | Select only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CA uniquely balances high 1500W surge capacity with surface-mount DO-214AB packaging - enabling automated assembly of automotive-grade power rails without sacrificing immunity margin or requiring board real estate for axial leads.

FAQ
What does the 'CA' suffix indicate in 1.5SMC130CA?
The 'CA' suffix in 1.5SMC130CA denotes a bidirectional configuration with tightened breakdown voltage tolerance (±5% for 1.5SMC130A vs. ±10% for 1.5SMC130). This ensures symmetrical clamping in both polarities and guarantees VBR between 124V and 137V at 1mA test current - critical for protecting balanced or AC-coupled circuits where polarity is undefined.
Can 1.5SMC130CA be used in place of a unidirectional 1.5SMC130A?
No - 1.5SMC130CA is specifically engineered as a bidirectional TVS with symmetrical characteristics, whereas 1.5SMC130A is unidirectional and features a cathode band marking. Substituting them requires verifying circuit topology: 1.5SMC130CA may be used in unidirectional applications but adds no benefit, while using 1.5SMC130A in bidirectional roles will fail to protect negative transients.
What is the maximum allowable surge repetition rate for 1.5SMC130CA?
The 1.5SMC130CA is rated for non-repetitive 10/1000µs surges per Fig.5. Repetitive operation is not characterized in the datasheet; thermal accumulation must be evaluated using RθJA = 50°C/W and TJ ≤ 150°C. For >1 pulse/second, derating per Fig.2 is mandatory - sustained repetition risks thermal runaway and parametric shift.
Does 1.5SMC130CA meet AEC-Q200 stress testing requirements?
No - while 1.5SMC130CA complies with ISO 7637-2 for automotive electrical transients, it is not qualified to AEC-Q200. Taiwan Semiconductor does not list this part in its AEC-Q200-certified portfolio. For AEC-Q200-compliant alternatives, consult TSC's AQ-series TVS diodes with explicit qualification reports.
How does junction capacitance affect 1.5SMC130CA's suitability for high-speed data lines?
The 1.5SMC130CA exhibits typical junction capacitance <100pF at 0V (per Fig.3), making it unsuitable for USB 2.0, HDMI, or Ethernet signal lines where sub-2pF loading is required. It is intended for power rails and low-frequency analog/sensor lines (<1MHz bandwidth); for high-speed data, pair with low-capacitance ESD arrays like TPD4E05U06.
