Product details
Overview
SMCJ130AH from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 130V working stand-off voltage (VWM), 144–159V breakdown voltage (VBR), and 209V maximum clamping voltage (VC) at 7.5A peak pulse current. It delivers AEC-Q101 qualification and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and ESD protection in power supply rails.
For engineers reviewing the SMCJ130AH datasheet, SMCJ130AH pinout, SMCJ130AH application, or SMCJ130AH equivalent, this device is selected for high-energy transient suppression where precise VWM, low clamping ratio, and automotive-grade reliability are required - especially in 12V/24V vehicle subsystems, industrial DC inputs, and telecom power interfaces.
Technical Context
The SMCJ130AH uses a glass-passivated silicon junction optimized for fast response (<1.0 ps rise time from 0 V to VBR min) and low leakage (<1 µA at 130 V). Its unidirectional configuration enables asymmetric surge handling on positive-polarity lines, with VF = 5.0 V at 100 A forward surge - consistent across SMCJ100H–SMCJ170H series.
Thermal performance is defined by RθJA = 55°C/W and RθJC = 10°C/W, supporting operation from –55°C to +150°C junction temperature. The device complies with JESD201 Class 2 whisker resistance and UL 94V-0 molding compound flammability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 144 V / 159 V @ 1 mA - Confirmed breakdown range ensures predictable turn-on under transients |
| VC @ IPPM | 209 V @ 7.5 A - Clamping voltage defines worst-case voltage seen by protected circuit during 10/1000 µs surge |
| PPK | 1500 W - Peak pulse power rating per 1 ms non-repetitive waveform (Fig.5) |
| IR @ VWM | <1 µA - Negligible leakage at rated stand-off, minimizing standby power loss |
| Package | DO-214AB (SMC) - Surface-mount outline with 0.210 g mass and matte tin-plated leads |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with cathode band marking; polarity-sensitive unidirectional device; terminals are solderable per J-STD-002; weight ≈ 0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage rail; completes conduction path during reverse-biased transient |
| Cathode | High-side input terminal | Connected to protected line (e.g., battery feed); carries full surge current into anode during clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood and chassis applications per stress test requirements |
| ISO 7637-2 compliance | Withstands standardized automotive transients including load dump (Pulse 5a/b), coupling (Pulse 1/2a/2b), and supply interruption (Pulse 3a/3b) |
| Glass passivated junction | Enhances long-term stability and moisture resistance vs. epoxy-passivated alternatives |
| Fast response time | <1.0 ps from 0 V to VBR min - limits voltage overshoot before clamping engages |
Applications
| Automotive Power Distribution | Industrial DC Input Protection |
|---|---|
Use Scenario: Protecting 24V battery-fed ECUs against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and downstream regulator input.

IC Role / Device Role / Timing Role: Final-stage transient guard before USB-C PD controller and system load. Use Value: Sub-1 µA leakage avoids measurable standby current increase; DO-214AB footprint supports automated placement in high-volume consumer assembly. |
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 PPK rating, same VWM/VBR/VC but lower surge capacity; SMB package (smaller thermal mass) | Lower energy handling limits use to sub-5A transients or non-automotive environments | Select when board space is constrained and peak surge current remains ≤4.5 A |
| 1.5KE130A | Through-hole DO-201 package; identical 130 V VWM and 209 V VC, but slower response (~1 ns) and no AEC-Q101 qualification | Lacks automotive qualification and surface-mount compatibility; suited for legacy or cost-sensitive prototyping | Choose only for manual assembly or where ISO 7637-2 compliance is not required |
Compared with SMBJ130A and 1.5KE130A, the SMCJ130AH provides higher surge robustness (1500 W vs. 600 W/1500 W), automotive qualification, and surface-mount scalability - making it the preferred choice for production automotive and industrial systems requiring repeatable, high-energy clamping.

FAQ
What is the clamping voltage of the SMCJ130AH under standard 10/1000 µs surge conditions?
The SMCJ130AH has a maximum clamping voltage (VC) of 209 V at 7.5 A peak pulse current (IPPM), measured per the 10/1000 µs waveform defined in Fig.5 of the datasheet. This value ensures protected circuits remain below critical overvoltage thresholds during standardized automotive and industrial transients.
Is the SMCJ130AH suitable for bidirectional transient protection?
No - the SMCJ130AH is a unidirectional TVS diode, intended for suppression on positively referenced lines only. For bidirectional protection, Taiwan Semiconductor specifies the SMCJ130CAH variant, which uses a center-tapped configuration and applies electrical characteristics in both directions.
Does the SMCJ130AH meet automotive qualification standards?
Yes - the SMCJ130AH is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements. Its glass-passivated junction, JESD201 Class 2 whisker resistance, and –55°C to +150°C operating range support under-hood and chassis deployment.
What is the forward voltage drop of the SMCJ130AH during high-current surge events?
The SMCJ130AH exhibits a forward voltage (VF) of 5.0 V at 100 A, consistent with all SMCJ100H–SMCJ170H unidirectional variants. This VF rating applies only during forward-conducting surge events (e.g., reverse-polarity connection fault), not during normal reverse-biased clamping operation.
How does the SMCJ130AH compare to the SMCJ130H in terms of breakdown voltage tolerance?
The SMCJ130AH has a tighter VBR range of 144–159 V (min/max @ 1 mA), versus SMCJ130H's wider 144–176 V range. This narrower specification improves consistency in turn-on timing across production lots, reducing design margin uncertainty in precision-clamp applications.
