Overview
SMCJ110CA-E3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 110 V standoff voltage (VWM), 1500 W peak pulse power (PPPM), 177 A peak pulse current (IPPM), and clamps to 177 V at rated surge, protecting sensitive ICs and MOSFETs in automotive and industrial systems.
For engineers reviewing the SMCJ110CA-E3/57T datasheet, SMCJ110CA-E3/57T pinout, SMCJ110CA-E3/57T application, or SMCJ110CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, 1500 W surge rating with 10/1000 µs waveform, RoHS-compliant E3 termination, and AEC-Q101 qualification eligibility via HE3 variant.
Technical Context
The SMCJ110CA-E3/57T operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced surges.
Designed for surface-mount assembly on standard PCB copper pads (8.0 mm × 8.0 mm per terminal), it meets MSL Level 1 per J-STD-020 and supports reflow up to 260 °C peak. Thermal resistance is 75 °C/W junction-to-ambient and 15 °C/W junction-to-lead, supporting reliable operation up to 150 °C junction temperature.

Pinout & Package
SMCJ110CA-E3/57T uses the SMC (DO-214AB) package: a 2-terminal, non-polarized surface-mount case with matte tin-plated leads solderable per J-STD-002. Bidirectional construction means no cathode/anode marking; both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Transient input/output node | Connected across protected line (e.g., CAN_H–CAN_L or VBUS–GND); conducts bidirectionally during overvoltage |
| Terminal 2 | Transient input/output node | Electrically identical to Terminal 1; no polarity dependency enables flexible PCB layout |

IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential pair or single-ended signal line to suppress EFT/burst noise and induced surges. Use Value: 1.0 µA leakage at 110 V VWM prevents signal offset in high-impedance sensor circuits while providing sub-ns response to 4 kV ESD per IEC 61000-4-2. |
| Telecom DC Power Feeds | Motor Drive Control Signal Lines |
Use Scenario: Protecting -48 V telecom rectifier outputs and PSE ports from lightning-induced surges on outside plant wiring. IC Role / Device Role / Timing Role: Standoff-rated TVS installed between power rail and chassis ground to clamp common-mode transients exceeding -48 V system rating. Use Value: 122–135 V VBR range ensures robust margin above -48 V nominal while maintaining low clamping voltage to protect -60 V tolerant interface ICs. | Use Scenario: Shielding isolated gate drivers (e.g., optocoupled or capacitive-isolated) from Miller-induced spikes during IGBT switching. IC Role / Device Role / Timing Role: Fast-response TVS on gate drive signal paths (e.g., HO/LO inputs) to prevent false turn-on due to dV/dt coupling. Use Value: Sub-1 ns response time and 177 V clamping limit gate-source voltage excursion, preserving driver reliability in 1200 V motor inverters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC110CA | Same VWM (110 V) and PPPM (1500 W), but in smaller SMA (DO-214AC) package with lower thermal mass | Limited to lower average power dissipation (PD = 3.0 W vs. 6.5 W); unsuitable for repeated surge duty cycles | Select SAC110CA only for space-constrained designs where surge repetition rate is low and board copper area is limited |
| SMCJ110A-E3/57T | Unidirectional variant with identical VWM, PPPM, and package; includes cathode band marking | Requires correct polarity placement; not usable on AC or differential lines without external rectification | Choose SMCJ110A-E3/57T only for DC rail protection where polarity is fixed and reverse conduction must be blocked |
Compared with SAC110CA and SMCJ110A-E3/57T, the SMCJ110CA-E3/57T provides bidirectional clamping in a thermally robust SMC package, making it optimal for differential interfaces and automotive power domains where polarity-agnostic surge suppression is required without sacrificing power handling or thermal performance.

FAQ
What does the "CA" suffix indicate in SMCJ110CA-E3/57T?
The "CA" suffix denotes a bidirectional configuration: the SMCJ110CA-E3/57T clamps voltage transients equally in both polarities, with no cathode marking. This distinguishes it from unidirectional variants like SMCJ110A-E3/57T, which require correct polarity orientation and block reverse current. The CA version is ideal for AC lines, differential buses, and any application where voltage polarity may reverse.
Is SMCJ110CA-E3/57T qualified for automotive use?
The SMCJ110CA-E3/57T itself is a commercial-grade RoHS-compliant part (E3 suffix). However, Vishay offers the functionally identical SMCJ110CAHE3 variant, which carries full AEC-Q101 qualification. Engineers designing for automotive applications should specify the HE3 version for qualification-critical systems, while the E3 version remains suitable for industrial and telecom designs requiring the same electrical performance.
What is the maximum clamping voltage of SMCJ110CA-E3/57T under surge conditions?
The SMCJ110CA-E3/57T clamps to a maximum of 177 V when subjected to its rated 177 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This VC value is measured at the device terminals under specified test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads), and defines the upper voltage limit imposed on protected circuitry during transient events.
How does the SMCJ110CA-E3/57T compare to SMCJ110A-E3/57T in terms of circuit integration?
The SMCJ110CA-E3/57T requires no polarity alignment during placement-its bidirectional symmetry allows direct mounting across any two nodes needing mutual overvoltage protection. In contrast, SMCJ110A-E3/57T has a cathode band and must be oriented correctly to avoid forward conduction during normal operation. This makes the CA version simpler to integrate in differential signaling and AC-coupled paths, reducing assembly risk and layout constraints.
What PCB layout guidance applies to SMCJ110CA-E3/57T for optimal surge performance?
For rated 1500 W surge handling, Vishay specifies mounting the SMCJ110CA-E3/57T on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. Trace width and internal plane connections must minimize inductance; short, wide traces to ground/power planes are essential. Avoid thermal reliefs on pads, and ensure adequate copper area for heat dissipation during repetitive surges-this directly impacts sustained clamping stability and device longevity.
