Product details
Overview
SMCG5.0CA-E3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 6.40–7.25 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps to ≤9.20 V at 163 A surge current - ideal for automotive sensor line protection against load dump and ESD.
For engineers reviewing the SMCG5.0CA-E3/9AT datasheet, SMCG5.0CA-E3/9AT pinout, SMCG5.0CA-E3/9AT application, or SMCG5.0CA-E3/9AT equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 rating, 150 °C junction temperature limit, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling single-device protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable VBR and low leakage (<1000 µA at VWM), while the low incremental surge resistance supports fast, predictable clamping under 10/1000 µs transients.
The device is rated for 1500 W peak pulse power per IEC 61000-4-5 and UL 497B, with thermal resistance RθJA = 75 °C/W on standard 0.31" × 0.31" pads. It meets AEC-Q101 stress testing for automotive use and is qualified to J-STD-020 MSL Level 1 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse voltage before clamping begins; defines operating margin for 5 V logic/sensor interfaces |
| VBR min/max | 6.40 V / 7.25 V at 10 mA - tight breakdown window ensures reliable triggering without false trips |
| VC @ IPPM | ≤9.20 V at 163 A - clamping voltage limits stress on downstream ICs during 10/1000 µs surges |
| PPPM | 1500 W - peak transient energy handling capacity per IEC 61000-4-5 Level 4 compliance |
| ID @ VWM | ≤1000 µA - low leakage preserves signal integrity and battery life in always-on circuits |
| TJ max | +150 °C - enables operation in under-hood automotive environments and industrial enclosures |
| MSL Level | Level 1 (J-STD-020) - supports lead-free reflow up to 260 °C without preconditioning |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing package with matte tin-plated leads, UL 94 V-0 molding compound, and no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load dump, jump-start, and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and chassis ground, absorbing transients before they reach the transceiver IC. Use Value: Prevents latch-up or permanent damage to 5 V-rated interface ICs by limiting voltage to ≤9.20 V during 1500 W surges. | Use Scenario: Safeguarding differential CAN_H/CAN_L lines in factory automation controllers exposed to inductive switching noise and ground bounce. IC Role / Device Role / Timing Role: Symmetric TVS pair (one per line) referenced to common ground, providing balanced clamping without disrupting differential signaling. Use Value: Maintains CAN signal integrity by clamping common-mode transients while preserving <100 pF junction capacitance at zero bias. |
| Consumer USB Port Protection | Telecom DSL Line Interface |
Use Scenario: Shielding USB 2.0 D+/D− data lines in portable devices from human-body-model (HBM) ESD and cable-induced surges. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector, shunting ESD current to ground before it reaches the USB PHY. Use Value: Achieves >15 kV HBM ESD immunity without degrading signal rise/fall times due to low clamping voltage and minimal parasitic capacitance. | Use Scenario: Protecting ADSL/VDSL line drivers and receivers from lightning-induced surges and AC power cross-talk on twisted-pair telephone lines. IC Role / Device Role / Timing Role: Primary protection device mounted at line entry point, coordinated with secondary GDT or MOV stages. Use Value: Withstands repeated 10/1000 µs surges up to 163 A while maintaining stable VBR and low leakage for 24/7 service reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/57T | Unidirectional; same VWM/VBR/PPPM but lacks bidirectional symmetry; SMA (DO-214AC) package | Requires separate devices for dual-rail or AC-coupled protection; not suitable for differential line pairs without redesign | Select only when unidirectional clamping suffices and board space allows SMA footprint |
| SMCJ5.0CA-E3/57T | Same bidirectional function and DO-214AB package; higher PPPM (1500 W vs. 1500 W identical), but larger 7.11 mm × 6.22 mm body vs. SMCG's 7.11 mm × 5.59 mm | Compatible in circuit function but requires PCB pad revision due to longer body and different terminal spacing | Choose when existing SMCJ footprint is fixed and AEC-Q101 qualification is confirmed for that variant |
Compared with SMAJ5.0A-E3/57T and SMCJ5.0CA-E3/57T, the SMCG5.0CA-E3/9AT delivers identical 1500 W surge capability in a more compact DO-215AB outline, with AEC-Q101 validation and MSL Level 1 reflow readiness - making it optimal for space-constrained automotive and industrial modules requiring bidirectional protection.

FAQ
What is the clamping voltage of the SMCG5.0CA-E3/9AT at its rated peak pulse current?
The SMCG5.0CA-E3/9AT clamps to a maximum of 9.20 V at its rated peak pulse current of 163 A under a 10/1000 µs waveform. This value is measured per IEC 61000-4-5 and ensures downstream 5 V ICs remain within safe operating voltage limits during surge events. The SMCG5.0CA-E3/9AT achieves this with low incremental resistance and a tightly controlled breakdown range of 6.40–7.25 V.
Is the SMCG5.0CA-E3/9AT suitable for automotive applications?
Yes, the SMCG5.0CA-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and body-control module environments. Its +150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and UL 497B recognition confirm suitability for ECU, ADAS sensor, and infotainment interface protection. The SMCG5.0CA-E3/9AT meets all stress tests defined in AEC-Q101 Rev D for transient suppressors.
Does the SMCG5.0CA-E3/9AT have polarity markings on the package?
No, the SMCG5.0CA-E3/9AT has no polarity markings because it is a bidirectional device - its terminals are functionally symmetric and interchangeable. Unlike unidirectional variants (e.g., SMCG5.0A), which feature a cathode band, the SMCG5.0CA-E3/9AT relies on identical electrical behavior in both directions, eliminating the need for orientation-dependent placement during SMT assembly.
What is the thermal resistance of the SMCG5.0CA-E3/9AT under standard mounting conditions?
The SMCG5.0CA-E3/9AT 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 - matching the test condition specified in the Vishay datasheet. This value assumes no additional heatsinking and defines the steady-state temperature rise at 6.5 W DC power dissipation. The SMCG5.0CA-E3/9AT also exhibits RθJL = 15 °C/W to the lead.
Can the SMCG5.0CA-E3/9AT be used in place of a unidirectional TVS like SMCG5.0A?
No - the SMCG5.0CA-E3/9AT is bidirectional and cannot replace a unidirectional TVS such as SMCG5.0A in circuits requiring forward conduction or DC bias blocking, like power rail protection. While both share identical VWM and PPPM ratings, the SMCG5.0CA-E3/9AT conducts equally in both directions and lacks a defined anode/cathode functional distinction. Substitution would require full circuit review and likely layout changes to maintain intended protection topology.
