Product details
Overview
1.5SMC130AH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 1500W peak pulse power, 130V breakdown voltage (124–137V), and 111V working stand-off voltage. It clamps transients to ≤179V at 8.7A, supports AEC-Q101 qualification, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and ESD protection.
For engineers reviewing the 1.5SMC130AH datasheet, 1.5SMC130AH pinout, 1.5SMC130AH application, or 1.5SMC130AH equivalent, this device is selected for robust overvoltage immunity in DC power rails, automotive ECUs, and industrial I/O interfaces where fast response (<1.0 ps), low leakage (<1 µA @ 111V), and high surge current handling are critical.
Technical Context
The 1.5SMC130AH uses a glass-passivated silicon junction optimized for unidirectional clamping with tight VBR tolerance (±5% typical). Its thermal design features RθJA = 50°C/W and RθJC = 15°C/W, enabling reliable operation up to TJ = +150°C in constrained PCB layouts.
It delivers 1500W peak pulse power per 1ms 10/1000µs waveform, with clamping voltage specified at 179V under 8.7A IPPM - a key parameter for ensuring downstream ICs remain below absolute maximum ratings during ISO 7637-2-compliant transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 124 V / 137 V - defines minimum and maximum voltage at which device enters avalanche conduction under 1mA test current; ensures consistent turn-on across production lots |
| VWM | 111 V - maximum continuous reverse operating voltage; sets safe DC rail margin before leakage rises significantly |
| VC @ IPPM | 179 V @ 8.7 A - clamping voltage during 10/1000µs surge; determines worst-case stress on protected circuitry |
| PPK | 1500 W - peak pulse power rating; defines transient energy absorption capability without failure |
| IR @ VWM | <1 µA - blocking leakage at rated stand-off voltage; minimizes standby power loss and signal distortion |
| TJ max | +150 °C - maximum junction temperature; enables use in under-hood automotive environments and high-power industrial enclosures |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, unidirectional configuration with cathode band marking. Case meets UL 94V-0 flammability rating; matte tin-plated leads comply with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input/Line side | Connected to protected line (e.g., battery feed); conducts during forward surge only in unidirectional mode |
| Cathode | Clamp/Return side | Connected to ground or low-impedance return path; provides low-impedance shunt during reverse avalanche |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | 600W peak power, SMB package (smaller footprint, higher RθJA = 65°C/W), same VBR range (124–137V) | Limited to lower-energy transients; unsuitable for full ISO 7637-2 Pulse 5a compliance | Select when board space is constrained and surge energy does not exceed 600W |
| 1.5KE130A | Through-hole DO-201 package, identical 1500W rating and VBR, but slower response (~1ns) and no AEC-Q101 qualification | Not suitable for automated SMT assembly or automotive under-hood use due to leaded construction and qualification gap | Select for legacy through-hole designs or non-automotive industrial applications requiring identical electrical specs |
Compared with SMBJ130A and 1.5KE130A, the 1.5SMC130AH uniquely combines 1500W surge capability, AEC-Q101 qualification, and SMT-ready DO-214AB packaging - making it the preferred choice for new automotive and high-reliability industrial designs requiring both performance and manufacturability.

FAQ
What is the clamping voltage of the 1.5SMC130AH under maximum rated surge current?
The 1.5SMC130AH has a maximum clamping voltage (VC) of 179 V when subjected to its rated peak pulse current (IPPM) of 8.7 A, measured using the standardized 10/1000 µs waveform. This value is guaranteed across temperature and production lot, ensuring predictable overvoltage protection for downstream components in the 1.5SMC130AH design.
Is the 1.5SMC130AH suitable for bidirectional transient suppression?
No - the 1.5SMC130AH is a unidirectional TVS diode, intended for DC rail protection with defined anode/cathode polarity. For bidirectional applications, Taiwan Semiconductor specifies the 1.5SMC130CAH variant, which uses a center-tapped dual-diode configuration. Using the 1.5SMC130AH in AC or floating-bus scenarios may result in forward conduction and failure.
Does the 1.5SMC130AH meet automotive qualification standards?
Yes - the 1.5SMC130AH is explicitly AEC-Q101 qualified and tested per ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms. Its DO-214AB package, glass-passivated junction, and MSL Level 1 rating further support automotive under-hood and chassis-mounted deployment in systems where the 1.5SMC130AH is specified.
What is the maximum steady-state power dissipation for the 1.5SMC130AH at room temperature?
The 1.5SMC130AH has a steady-state power dissipation (PD) rating of 6.5 W at TA = 25°C. This value decreases linearly above 25°C per the derating curve in Figure 2 of the datasheet, reaching zero at +150°C junction temperature - a critical constraint when calculating thermal margins in sealed enclosures where the 1.5SMC130AH operates continuously near its VWM.
How does the 1.5SMC130AH compare to the 1.5SMC130H in terms of breakdown voltage tolerance?
The 1.5SMC130AH has a tighter VBR tolerance: 124–137 V (±5% around nominal 130 V), whereas the 1.5SMC130H spans 117–143 V (±10%). This narrower spread improves system-level predictability in clamping behavior and reduces design margin requirements - a key differentiator when selecting between the 'H' and 'AH' variants of the 1.5SMC130AH family.
