Product details
Overview
SMCG100CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for high-energy surge protection with 1500 W peak pulse power (10/1000 µs), 162 V clamping voltage at 9.3 A peak pulse current, and 100 V standoff voltage. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, CAN transceivers, and power supply rails against inductive switching transients and ESD.
For engineers reviewing the SMCG100CA-E3/57T datasheet, SMCG100CA-E3/57T pinout, SMCG100CA-E3/57T application, or SMCG100CA-E3/57T equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal resistance (75 °C/W), RoHS-compliant E3 termination, and AEC-Q101 qualification status - all critical for automotive-grade circuit protection design.
Technical Context
The SMCG100CA-E3/57T operates as a bidirectional avalanche diode, exhibiting symmetrical breakdown in both polarities with minimum/maximum breakdown voltages of 111 V / 123 V at 1 mA test current. Its glass-passivated junction ensures stable leakage (<1.0 µA at 100 V) and fast response time (<1 ns) to transient events.
Thermally, it features RθJA = 75 °C/W on standard 8.0 mm × 8.0 mm copper pads and supports continuous operation from –55 °C to +150 °C junction temperature. The device meets J-STD-020 MSL Level 1 and is rated for 200 A non-repetitive forward surge (8.3 ms half-sine) in unidirectional mode - though not applicable here due to its bidirectional configuration.

Applications
| Automotive Sensor Protection | CAN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting analog output sensors (e.g., pressure, temperature) in engine bay modules exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across sensor supply and ground, shunting transients before they reach precision ADC inputs. Use Value: Maintains signal integrity by limiting voltage excursions to ≤162 V during 100 V-rated system surges, preventing ADC saturation or latch-up. |
Use Scenario: Safeguarding high-speed CAN FD transceivers (e.g., TCAN1042, SN65HVD256) against ESD and coupled noise on differential bus lines. IC Role / Device Role / Timing Role: Low-capacitance (≈30 pF typical) bidirectional TVS placed across CAN_H/CAN_L, referenced to ground via common-mode choke. Use Value: Clamps common-mode surges without distorting differential signaling - preserves >5 Mbps CAN FD timing margins and bit error rate. |
| Industrial PLC I/O Protection | Telecom Power Rail Clamp |
Use Scenario: Shielding 24 V DC digital input modules in programmable logic controllers from field-wiring induced transients and relay coil kickback. IC Role / Device Role / Timing Role: Primary surge clamp on input channel, positioned upstream of optocoupler or Schmitt trigger input stage. Use Value: Absorbs up to 1500 W pulses without degradation, enabling robust operation in factory-floor environments with frequent inductive switching. |
Use Scenario: Protecting 48 V intermediate bus rails in telecom base station power supplies from lightning-induced surges on AC/DC front-end inputs. IC Role / Device Role / Timing Role: Secondary-stage TVS across bulk capacitor output, coordinated with MOVs and fuses for staged surge coordination. Use Value: Provides precise 100 V standoff and 162 V clamping - avoids premature triggering while ensuring downstream DC/DC converter survival during 1 kV/1 kA surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100CA | Same 100 V VWM, but lower PPPM (400 W) and higher VC (165 V @ 2.4 A); SMA (DO-214AC) package, larger footprint | Limited to lower-energy transients (IEC 61000-4-5 Level 3); unsuitable for automotive load dump | Select when cost sensitivity outweighs surge energy requirement and board space permits larger package |
| TPSMD100CA | Same 100 V VWM, 1500 W PPPM, but higher VC (170 V @ 8.8 A); TO-277 package, no gull-wing leads | Requires different reflow profile and manual inspection due to bottom-terminal construction; lower thermal resistance (RθJA ≈ 50 °C/W) | Prefer for thermally constrained designs where PCB real estate allows through-hole or SMT bottom-termination layout |
Compared with SMAJ100CA and TPSMD100CA, the SMCG100CA-E3/57T delivers identical standoff and superior surge handling in a compact, AEC-Q101-qualified gull-wing package - making it the optimal choice for space-constrained, high-reliability automotive and industrial signal-line protection.

FAQ
What is the clamping voltage of the SMCG100CA-E3/57T at its rated peak pulse current?
The SMCG100CA-E3/57T has a maximum clamping voltage (VC) of 162 V at 9.3 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings. The SMCG100CA-E3/57T maintains this clamping performance across its full operating temperature range.
Is the SMCG100CA-E3/57T suitable for automotive applications?
Yes, the SMCG100CA-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its –55 °C to +150 °C operating junction temperature range, MSL Level 1 reflow compatibility, and validation against HTGB, TCT, and HTRB stress tests confirm suitability for engine control units, ADAS camera modules, and body electronics. The SMCG100CA-E3/57T meets ISO 7637-2 Pulse 5a requirements when mounted per recommended pad layout.
Does the SMCG100CA-E3/57T have polarity markings?
No, the SMCG100CA-E3/57T is a bidirectional TVS diode and carries no polarity marking on its SMCG (DO-215AB) package. Its symmetrical construction means both terminals are functionally identical - eliminating orientation concerns during placement and enabling use on AC-coupled or floating signal paths. This contrasts with unidirectional variants like SMCG100A, which feature a cathode band.
What is the thermal resistance of the SMCG100CA-E3/57T?
The SMCG100CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the standard 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad per terminal. This value assumes JEDEC-standard board conditions and is essential for calculating steady-state power dissipation limits and transient thermal response. The SMCG100CA-E3/57T also exhibits RθJL = 15 °C/W (junction-to-lead), supporting localized heat transfer in high-power pulse scenarios.
How does the SMCG100CA-E3/57T differ from unidirectional SMCG100A?
The SMCG100CA-E3/57T is bidirectional with symmetrical breakdown in both directions (VBR = 111–123 V), while the SMCG100A is unidirectional with cathode marking and forward conduction capability (VF = 3.5 V at 100 A). The SMCG100CA-E3/57T has no forward voltage drop specification and cannot conduct DC current - it is strictly for AC or bipolar transient suppression. Both share identical PPPM (1500 W), package (SMCG), and AEC-Q101 qualification, but only the SMCG100CA-E3/57T is appropriate for differential or floating-line protection.
