Product details
Overview
SMCJ130CAH from Taiwan Semiconductor is a bidirectional 1500W surface-mount 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 impulse current. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients and ESD.
For engineers reviewing the SMCJ130CAH datasheet, SMCJ130CAH pinout, SMCJ130CAH application, or SMCJ130CAH equivalent, this device is selected for high-energy surge immunity in 12V/24V/48V DC systems where AEC-Q101 qualification, sub-1ps response time, and <1µA reverse leakage above 10V are critical design requirements.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, enabling robust protection of differential or AC-coupled signal/power lines without polarity dependency. Its glass-passivated junction ensures stable VBR tolerance and low leakage across -55°C to +150°C junction temperature range.
Designed for fast transient suppression, it delivers clamping within <1.0ps from 0V to VBR(min), with thermal resistance RθJC = 10°C/W and RθJA = 55°C/W - enabling reliable operation under repetitive surge conditions when mounted on adequate copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 130V nominal systems. |
| VBR @ IT=1mA | 144–159 V - Breakdown occurs within this band at 1mA test current; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM=7.5A | 209 V - Clamped voltage seen by protected circuit during 10/1000µs surge; limits stress on downstream components. |
| PPK | 1500 W - Peak pulse power handling per single 1ms waveform; supports ISO 7637-2 Pulse 5a (load dump) surges. |
| IR @ VWM | <1 µA - Negligible leakage at rated stand-off voltage; avoids power loss or false triggering in high-impedance circuits. |
| TJ Range | -55°C to +150°C - Full automotive-grade operating temperature envelope; validated per AEC-Q101 stress tests. |
| Package | DO-214AB (SMC) - Industry-standard surface-mount outline with 0.210g mass and UL 94V-0 molding compound. |

|---|---|
Use Scenario: Protecting 24V CAN/LIN bus power rails and sensor supply lines against load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary transient clamp placed upstream of LDOs and CAN transceivers to limit voltage excursion during ISO 7637-2 Pulse 5a (load dump). Use Value: Clamps to 209V at 7.5A, preventing damage to 36V-rated regulators and ensuring uninterrupted communication during 120V/350ms transients. |
Use Scenario: Safeguarding analog input channels (4–20mA, 0–10V) on programmable logic controllers exposed to field wiring surges. IC Role / Device Role / Timing Role: Bidirectional shunt protector across input terminals to absorb induced lightning transients and relay coil kickback. Use Value: Symmetric clamping ensures equal protection for positive/negative transients; <1µA leakage avoids measurement error in high-impedance sensing paths. |
| Telecom DC Power Feeds | Renewable Energy Inverter Control |
Use Scenario: Shielding 48V PoE++ or remote radio unit (RRU) power inputs from induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Secondary-stage TVS after primary GDT/MOV, providing precise low-clamp protection for DC-DC converters and PMICs. Use Value: 209V VC allows safe operation with 57V max input rating on buck controllers; DO-214AB footprint enables automated placement in high-volume telecom assemblies. |
Use Scenario: Guarding gate driver supply rails in solar string inverters subject to grid-switching transients and ground potential rise. IC Role / Device Role / Timing Role: Fast-response clamp on isolated 15V auxiliary supplies feeding IGBT/SiC gate drivers to prevent false turn-on. Use Value: Sub-1ps response prevents millisecond-scale overvoltage from propagating to sensitive level-shifters; AEC-Q101 reliability aligns with 25-year field life targets. |
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 | Lower PPK (600W), same VWM/VBR/VC specs, SMB package (smaller thermal mass) | Not suitable for ISO 7637-2 Pulse 5a (load dump); limited to lower-energy transients like ESD or data line surges | Select only if system-level testing confirms 600W clamping energy suffices and PCB layout restricts to SMB footprint. |
| 1.5KE130CA | Higher PPK (1500W), axial leaded DO-201 package, longer lead inductance (~15nH vs. <2nH for SMC) | Unsuitable for high-frequency transients (>10MHz) due to parasitic inductance; incompatible with automated SMT assembly | Choose only for through-hole prototyping or legacy repair; avoid in new designs requiring AEC-Q101 or high-speed clamping. |
Compared with SMBJ130CA and 1.5KE130CA, the SMCJ130CAH uniquely combines 1500W surge capability, DO-214AB SMT compatibility, AEC-Q101 qualification, and sub-1ps response - making it the only option qualified for production automotive power rail protection where both energy handling and speed are mandatory.

FAQ
What does the "CAH" suffix indicate in SMCJ130CAH?
The "CAH" suffix in SMCJ130CAH denotes a bidirectional TVS diode (C = bidirectional, A = tightened VBR tolerance ±5%, H = high-temp grade). Unlike unidirectional variants (e.g., SMCJ130H), SMCJ130CAH conducts identically in both directions - essential for protecting AC-coupled signals or floating DC buses where polarity is undefined. This is confirmed in the datasheet's "Devices for bipolar applications" section.
Is SMCJ130CAH compliant with AEC-Q101, and what tests does that include?
Yes, SMCJ130CAH is explicitly AEC-Q101 qualified per the datasheet's FEATURES list. This includes stress testing for high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and electrostatic discharge (HBM/MM). These validations ensure reliability in automotive under-hood and chassis applications where junction temperatures reach 150°C and thermal cycling exceeds 1000 cycles.
What is the maximum clamping voltage (VC) of SMCJ130CAH, and under what test condition is it specified?
The maximum clamping voltage of SMCJ130CAH is 209 V, measured at a peak impulse current (IPPM) of 7.5 A using the 10/1000 µs double-exponential surge waveform defined in Fig.5 of the datasheet. This value is guaranteed across the full operating temperature range and represents the highest voltage the protected circuit will experience during a standardized transient event.
How does SMCJ130CAH differ from SMCJ130AH in terms of electrical performance?
SMCJ130CAH is bidirectional (C), while SMCJ130AH is unidirectional (no C). Their VBR ranges differ: SMCJ130AH has VBR = 144–176 V (±10%), whereas SMCJ130CAH has tighter VBR = 144–159 V (±5%, denoted by "A"). Clamping voltage also differs: SMCJ130CAH VC = 209 V @ 7.5A, versus SMCJ130AH VC = 231 V @ 6.8A - reflecting optimized symmetry and tighter tolerance for bidirectional use.
Can SMCJ130CAH be used in place of SMCJ130A in a design?
No - SMCJ130CAH and SMCJ130A are functionally distinct. SMCJ130A is unidirectional with anode/cathode polarity and forward voltage drop; SMCJ130CAH is bidirectional with no polarity marking. Substituting one for the other would cause incorrect clamping behavior in DC circuits or failure to protect AC paths. The datasheet explicitly separates "unidirectional" and "bidirectional" device families and warns against interchangeability.
