Product details
Overview
1.5SMC130A from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 130V breakdown voltage (124–137V), 111V working stand-off voltage, 179V maximum clamping voltage at 8.7A peak pulse current, and 1500W peak pulse power dissipation per 10/1000μs waveform - deployed in telecom power inputs and industrial I/O interfaces.
For engineers reviewing the 1.5SMC130A datasheet, 1.5SMC130A pinout, 1.5SMC130A application, or 1.5SMC130A equivalent, key selection criteria include clamping voltage margin vs. protected IC VMAX, leakage current at operating voltage, thermal derating above 25°C, and DO-214AB (SMC) board space constraints.
Technical Context
This TVS operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response (<1.0 ps) to ESD and lightning-induced transients. Its 1500W peak power rating is defined at TA = 25°C with 10/1000μs waveform and derates linearly above that ambient temperature per Fig.2.
Electrical behavior follows ANSI/IEEE C62.35 standards: breakdown voltage is measured after 30ms square-wave IT pulse; clamping voltage VC is guaranteed at specified IPPM; and IR ≤ 1 μA is verified at VWM = 111V - ensuring minimal standby loading on 12V–48V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 124 V / 137 V - defines minimum and maximum voltage at which avalanche conduction begins under 1 mA test current; sets lower bound for overvoltage trip threshold. |
| VWM | 111 V - maximum continuous DC or RMS voltage the device blocks without significant leakage; must exceed system nominal voltage (e.g., 96VDC telecom) by ≥10%. |
| VC@IPPM | 179 V - clamped voltage across terminals during 8.7A 10/1000μs surge; determines maximum stress seen by downstream ICs. |
| PPK | 1500 W - peak pulse power handling capability; validates robustness against ISO 7637-2 Pulse 1/2a/2b/3a/3b automotive transients and IEC 61000-4-5 surges. |
| IR@VWM | ≤1 μA - reverse leakage at rated stand-off voltage; ensures negligible quiescent current draw in battery-backed or low-power monitoring circuits. |
| TJ max | 150 °C - maximum junction temperature; enables operation in sealed enclosures or high-ambient industrial environments when combined with RθJA = 50 °C/W. |
| Package | DO-214AB (SMC) - surface-mount outline with 7.11 mm × 6.22 mm footprint and 2.62 mm height; compatible with standard SMT reflow profiles and J-STD-002 solderability. |
Pinout & Package
Package: DO-214AB (SMC), unidirectional configuration with cathode band marking. Matte tin-plated leads meet JESD 201 Class 2 whisker resistance and RoHS/halogen-free compliance (IEC 61249-2-21).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or lowest potential node; establishes reference for clamping action during positive transients. |
| Cathode | Protected line input terminal | Connected to line being protected (e.g., +110V telecom rail); conducts avalanche current to anode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under humidity and thermal cycling per J-STD-020 Level 1 moisture sensitivity. |
| Clamping voltage ≤179 V at 8.7 A | Provides ≥20% margin below typical 220V-rated industrial interface IC absolute maximum ratings, reducing risk of latch-up or permanent damage. |
| Response time <1.0 ps | Enables suppression of sub-nanosecond ESD events (IEC 61000-4-2 Contact ±8 kV) before sensitive logic or analog front-ends are stressed. |
| Meets ISO 7637-2 Pulse 1/2a/2b/3a/3b | Validates suitability for automotive body electronics, infotainment power supplies, and CAN/LIN bus protection where load-dump and inductive switching transients occur. |
| UL 94V-0 molding compound | Confirms flame-retardant encapsulation required for safety-critical telecom and industrial equipment certifications (UL/EN 62368-1). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A (Bourns) | Same DO-214AA (SMB) package; 130V VBR; 1000W PPK; 187V VC @ 5.3A - lower power rating and higher clamping voltage. | Less suitable for high-energy ISO 7637-2 Pulse 5a; better fit for space-constrained PCBs where 7.11×6.22mm SMC footprint is unavailable. | Select SMBJ130A only if board layout prohibits DO-214AB and system surge energy remains ≤1000W. |
| 1.5KE130A (ON Semiconductor) | Through-hole DO-201AE package; identical 130V VBR and 179V VC; same 1500W rating but higher RθJA (75°C/W) limits high-temp operation. | Requires wave soldering or hand assembly; unsuitable for fully automated SMT lines; preferred for prototyping or legacy through-hole designs. | Choose 1.5KE130A only for manual assembly or mixed-technology boards where SMT process compatibility is not required. |
Compared with SMBJ130A and 1.5KE130A, the 1.5SMC130A delivers superior thermal performance (RθJA = 50°C/W), full SMT automation support, and identical clamping performance in a compact surface-mount package - making it optimal for high-volume industrial and telecom production.

FAQ
What is the clamping voltage of the 1.5SMC130A under maximum rated surge current?
The 1.5SMC130A has a maximum clamping voltage (VC) of 179 V when subjected to its rated peak pulse current (IPPM) of 8.7 A with a 10/1000μs waveform. This value is guaranteed across temperature and manufacturing lot variations per the datasheet's electrical specifications table and is critical for ensuring downstream components remain within their absolute maximum voltage ratings during transient events.
Is the 1.5SMC130A unidirectional or bidirectional?
The 1.5SMC130A is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its single cathode band marking and specification of forward voltage (VF = 5.0 V @ 50 A). It protects against positive transients only - negative excursions are blocked by its high reverse stand-off voltage (VWM = 111 V) and low leakage (<1 μA).
What is the thermal resistance from junction to ambient for the 1.5SMC130A?
The 1.5SMC130A has a typical junction-to-ambient thermal resistance (RθJA) of 50 °C/W when mounted on a standard FR-4 PCB with 1 in² copper pad area. This value assumes no additional heatsinking and is used to calculate allowable power dissipation at elevated ambient temperatures using the derating curve in Figure 2 of the datasheet.
Does the 1.5SMC130A meet automotive transient immunity standards?
Yes, the 1.5SMC130A meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements for automotive electronic components. Its 1500W peak pulse power rating and sub-1.0 ps response time enable effective suppression of both slow (load dump) and fast (inductive switch-off) transients encountered in vehicle electrical systems.
What is the maximum operating junction temperature for the 1.5SMC130A?
The 1.5SMC130A has a maximum junction temperature (TJ) of +150 °C, as specified in the Absolute Maximum Ratings table. This rating supports operation in sealed enclosures or high-ambient industrial environments, provided thermal design accounts for RθJA = 50 °C/W and steady-state power dissipation does not exceed 6.5 W at 25°C ambient.
