IC Role / Device Role / Timing Role: TVS placed across bridge rectifier output to clamp switching spikes and external surges before bulk capacitor. Use Value: 1500 W rating handles 2 kV/500 A combination wave tests; RoHS-compliant HE3 suffix meets global regulatory compliance for consumer shipments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC130CA | Same VWM (130 V) and VC (209 V), but lower PPPM (600 W); smaller SMA package (DO-214AC). | Limited to lower-energy surges (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 load dump. | Select when board space is constrained and surge energy is <600 W; verify thermal derating on small pads. |
| SMCJ130CAHM3/57T | Identical electrical specs and AEC-Q101 qualification; halogen-free molding compound (HM3 vs HE3). | No functional difference; required only where halogen-free compliance is mandated by OEM or regional regulation. | Choose HM3 variant if RoHS + halogen-free certification (e.g., JESD201 Class 2) is contractually required. |
Compared with SAC130CA, SMCJ130CAHE3/57T delivers 2.5× higher surge energy handling and robustness in automotive under-hood environments; versus SMCJ130CAHM3/57T, it offers identical protection performance with standard RoHS compliance - simplifying procurement where halogen-free is not mandated.

FAQ
What is the clamping voltage of SMCJ130CAHE3/57T at its rated peak pulse current?
The SMCJ130CAHE3/57T has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 7.2 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry remains within safe voltage limits during surge events - critical for protecting 200 V-rated capacitors and 16-bit ADC reference rails in automotive ECUs.
Is SMCJ130CAHE3/57T qualified for automotive applications?
Yes, SMCJ130CAHE3/57T is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its part number and documented in Vishay's official datasheet (Document Number: 88394, Revision: 09-Jan-2024). This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - making SMCJ130CAHE3/57T suitable for use in engine control modules, body electronics, and ADAS power domains.
How does the bidirectional design of SMCJ130CAHE3/57T affect its circuit implementation?
The bidirectional design of SMCJ130CAHE3/57T means it provides symmetrical clamping in both polarities - eliminating the need for polarity awareness during placement and enabling use across AC-coupled lines, differential buses (e.g., RS-485), or ungrounded power rails. Unlike unidirectional TVS diodes, SMCJ130CAHE3/57T has no cathode band marking and functions identically regardless of terminal orientation, reducing assembly errors and simplifying schematic symbol usage.
What is the thermal resistance of SMCJ130CAHE3/57T, and how does it impact layout?
The SMCJ130CAHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value directly informs PCB copper area requirements: reducing pad size increases RθJA and risks thermal runaway during repetitive surges. For high-duty-cycle applications like industrial motor drives, designers should maintain minimum pad dimensions or add internal ground planes to sustain reliable operation at TJ ≤ 150 °C.
Can SMCJ130CAHE3/57T replace SMCJ130AHE3/57T in a design?
No - SMCJ130CAHE3/57T is bidirectional, while SMCJ130AHE3/57T is unidirectional. They share identical VWM (130 V), VBR (144–159 V), and PPPM (1500 W), but differ in polarity behavior: SMCJ130AHE3/57T conducts forward surge current (IFSM = 200 A) and requires correct cathode orientation, whereas SMCJ130CAHE3/57T clamps equally in both directions with no polarity marking. Swapping them may cause unintended conduction or failed protection in DC-biased circuits.
