Product details
Overview
SMCJ130H from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode with a 130V working stand-off voltage (VWM), 144–176V breakdown voltage (VBR), and 231V maximum clamping voltage (VC) at 6.8A peak pulse current. It features AEC-Q101 qualification, ISO 7637-2 compliance (Pulse 1/2a/2b/3a/3b), and glass passivated junction for robust ESD and surge immunity in automotive power lines.
For engineers reviewing the SMCJ130H datasheet, SMCJ130H pinout, SMCJ130H application, or SMCJ130H equivalent, this device is selected for high-energy transient protection in 12V/24V/48V DC systems where fast response (<1.0 ps), low leakage (<1 µA @ 130V), and DO-214AB package compatibility are critical design requirements.
Technical Context
The SMCJ130H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its VBR range (144–176V @ 1 mA). Its clamping action limits transients to ≤231V at 6.8A (10/1000 µs waveform), enabling protection of downstream MOSFETs, controllers, and CAN/LIN interfaces against load dump and inductive switching events.
Thermally, it delivers RθJA = 55°C/W and RθJC = 10°C/W, supporting continuous operation up to TJ = 150°C. The DO-214AB (SMC) package provides 0.210g mass, matte tin-plated leads, and UL 94V-0 molding - optimized for reflow-compatible automated placement in automotive ECUs and industrial power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines system DC bus rating compatibility |
| VBR min/max | 144 V / 176 V @ 1 mA - Confirmed avalanche onset range; ensures reliable triggering above nominal 130V rail |
| VC @ IPPM | 231 V @ 6.8 A (10/1000 µs) - Peak clamped voltage seen by protected circuit; determines minimum safe voltage margin for downstream ICs |
| PPK | 1500 W - Single-pulse surge power handling; supports ISO 7637-2 Pulse 5a (load dump) up to 120 V/350 ms |
| IR @ VWM | <1 µA - Negligible leakage at rated stand-off; avoids parasitic current draw in always-on automotive modules |
| TJ max | +150 °C - Junction temperature limit; enables use in under-hood environments without derating below 125°C ambient |
| Package | DO-214AB (SMC) - Standardized 2-pin surface-mount outline; compatible with IPC-7351B SMC footprint and J-STD-002 solderability |
Pinout & Package
SMCJ130H uses the DO-214AB (SMC) package: a rectangular, surface-mount case with cathode band marking on one end. Leads are matte tin-plated, compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is unidirectional - cathode band denotes the terminal connected to the protected circuit's ground reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input side of protected line (e.g., battery feed) | Connected to higher-potential node; absorbs positive transients when reverse-biased |
| Cathode | Ground reference / return path | Marked with band; ties to system ground plane to shunt surge current safely away from ICs |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (ignition noise) waveforms |
| Glass passivated junction | Enhances long-term stability and moisture resistance vs. epoxy-passivated alternatives; supports 150°C TJ operation |
| Fast response time | <1.0 ps rise time from 0 V to VBR - faster than typical MOVs or polymer TVS, minimizing overshoot during nanosecond transients |
| Moisture sensitivity level 1 | No floor life limitation or baking requirement prior to reflow; simplifies SMT manufacturing flow |
Applications
| Automotive Power Distribution | Industrial PLC I/O Protection |

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 | Lower PPK (600W), smaller SMB package (DO-214AA), 245V VC @ 2.5A | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy transients in non-automotive consumer gear | Select only if space-constrained and surge energy ≤600W; verify thermal margin with RθJA = 85°C/W |
| 1.5KE130A | Through-hole TO-218 package, same 130V VWM, but 243V VC @ 6.2A and 1500W rating | Requires PCB through-hole mounting; incompatible with fully SMT production flows | Choose when legacy board reuse or manual repair is prioritized over automated assembly efficiency |
Compared with SMBJ130A and 1.5KE130A, the SMCJ130H delivers identical 130V stand-off and 1500W surge rating in a surface-mount DO-214AB package with AEC-Q101 and ISO 7637-2 validation - making it the only option qualified for new automotive designs requiring zero layout change and full compliance traceability.

FAQ
What is the clamping voltage of SMCJ130H at its rated peak pulse current?
The SMCJ130H has a maximum clamping voltage (VC) of 231 V at 6.8 A peak pulse current (IPPM), tested with the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ130H maintains this clamping performance across its full operating temperature range (−55°C to +150°C).
Is SMCJ130H unidirectional or bidirectional, and how is polarity identified?
The SMCJ130H is a unidirectional TVS diode, designed for DC line protection where transients occur only in one polarity. Polarity is marked by a cathode band on the DO-214AB package - the banded end connects to ground or the low-side reference, while the anode connects to the protected supply rail. Bidirectional variants use CH or CAH suffixes (e.g., SMCJ130CH), which are not applicable to the SMCJ130H.
Does SMCJ130H meet automotive qualification standards?
Yes, the SMCJ130H is AEC-Q101 qualified and meets ISO 7637-2 test requirements for Pulse 1, 2a, 2b, 3a, and 3b. These certifications confirm its suitability for automotive power net applications including engine control, body electronics, and ADAS subsystems. Full qualification reports and test data are available upon request for SMCJ130H.
What is the maximum steady-state power dissipation for SMCJ130H?
The SMCJ130H has a steady-state power dissipation (PD) rating of 5 W at TA = 25°C, as specified in its absolute maximum ratings table. This value applies only to continuous DC or low-frequency reverse bias conditions - not transient events. For surge protection, the device relies on its 1500W peak pulse rating (PPK), which is valid for non-repetitive 1 ms pulses per Fig.5 in the datasheet.
How does the SMCJ130H compare to SMCJ130AH in terms of electrical performance?
The SMCJ130H has a VBR range of 144–176 V and VC = 231 V, while the SMCJ130AH variant offers tighter VBR (144–159 V) and lower VC = 209 V at 7.5 A. Both share identical VWM (130 V), PPK (1500 W), and DO-214AB packaging. The "A" grade provides improved consistency for designs requiring tighter clamping tolerance, whereas the standard SMCJ130H offers broader availability and cost optimization for general-purpose use.
