Product details
Overview
SMCG60CA-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 on signal and power lines. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), clamping voltage of 96 V at 15.5 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG60CA-E3/9AT datasheet, SMCG60CA-E3/9AT pinout, SMCG60CA-E3/9AT application, or SMCG60CA-E3/9AT equivalent, this device is selected for high-energy surge suppression in automotive sensor interfaces, industrial I/O protection, and telecom line conditioning where bidirectional clamping, low clamping ratio, and MSL Level 1 solderability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities with identical VBR min/max (66.7 V / 73.7 V), ID ≤ 1.0 µA at VWM = 60 V, and VC = 96 V at IPPM = 15.5 A under 10/1000 µs waveform. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the DO-215AB package supports automated SMT placement and meets UL 94 V-0 flammability.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, enabling operation from –55 °C to +150 °C junction temperature. The device is rated for 200 A IFSM (unidirectional only - not applicable here), but as a CA-suffix part, it delivers full bidirectional surge capability without polarity marking.
Key Specifications

| Telecom Line Conditioning | Automotive Body Control Module |
Use Scenario: Protecting RS-485 transceivers in base station remote units exposed to induced surges on long outdoor cable runs. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed adjacent to transceiver pins to minimize signal distortion while suppressing ±30 kV ESD and 1 kV ring wave events. Use Value: Sub-1 µA leakage at 60 V VWM preserves common-mode rejection and avoids bias current errors in precision differential receivers. |
Use Scenario: Securing door module CAN FD transceivers and LED driver outputs against battery reverse connection and jump-start transients. IC Role / Device Role / Timing Role: Dual-role protector on both power rail and data line - clamps negative transients (e.g., −14 V reverse battery) and positive spikes (e.g., +120 V load dump). Use Value: Symmetrical bidirectional response enables single-device protection of both polarities, reducing BOM count and PCB area versus discrete unidirectional solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA | Same VWM (60 V), lower PPPM (400 W), SMA (DO-214AC) package, higher RθJA (110 °C/W) | Limited to lower-energy surges (IEC 61000-4-2 Level 3); unsuitable for ISO 7637-2 Pulse 5a | Select when cost or footprint is prioritized over automotive-grade surge capacity and thermal performance. |
| SMCJ60CA | Same VWM (60 V), identical PPPM (1500 W), larger SMC (DO-214AB) package, same AEC-Q101 qualification | Requires more PCB area; better thermal dissipation (RθJA = 50 °C/W) but less compatible with fine-pitch automated placement | Select when higher thermal margin is needed in high-power industrial drives or when legacy SMC footprint is locked. |
Compared with SMAJ60CA and SMCJ60CA, SMCG60CA-E3/9AT delivers optimal balance of automotive-grade reliability, compact DO-215AB footprint, and full 1500 W surge capability - making it preferred for space-constrained, high-reliability modules requiring AEC-Q101 validation and MSL Level 1 assembly compatibility.

FAQ
What is the clamping voltage of SMCG60CA-E3/9AT at its rated peak pulse current?
The SMCG60CA-E3/9AT has a maximum clamping voltage (VC) of 96 V at its specified peak pulse current (IPPM) of 15.5 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and reflects the actual voltage seen by protected circuitry during a full-power surge event. The 96 V clamping level is confirmed in the Vishay datasheet Document Number 88457, page 2, Electrical Characteristics table.
Is SMCG60CA-E3/9AT suitable for automotive applications?
Yes, SMCG60CA-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and body control module applications. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and operation from –55 °C to +150 °C. The "HE3" and "HM3" variants in the same family add halogen-free and enhanced qualification, but SMCG60CA-E3/9AT itself carries full AEC-Q101 certification per the Vishay datasheet revision 09-Jan-2024.
Does SMCG60CA-E3/9AT have polarity markings on the package?
No, SMCG60CA-E3/9AT does not have polarity markings because it is a bidirectional TVS diode. As stated in the Vishay datasheet, "no marking on bidirectional types." Both terminals are functionally identical - the device clamps symmetrically in either direction, so PCB layout does not require orientation alignment. This simplifies placement and eliminates risk of reverse installation.
What is the thermal resistance of SMCG60CA-E3/9AT from junction to ambient?
The typical thermal resistance from junction to ambient (RθJA) for SMCG60CA-E3/9AT is 75 °C/W, measured on the minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad layout per terminal. This value appears in the Thermal Characteristics section of the Vishay datasheet (Document Number 88457, page 3). It assumes standard FR-4 board material and defines the steady-state temperature rise under DC power dissipation.
How does SMCG60CA-E3/9AT differ from unidirectional SMCG60A-E3/9AT?
SMCG60CA-E3/9AT is bidirectional with symmetrical breakdown and clamping in both polarities, while SMCG60A-E3/9AT is unidirectional and features a cathode band marking. Their VWM (60 V) and PPPM (1500 W) are identical, but SMCG60A has IFSM = 200 A (8.3 ms half-sine) and VF = 3.5 V at 100 A - parameters irrelevant to the CA version. The CA variant is used where AC or differential signals require polarity-agnostic protection, such as in CAN, LIN, or RS-485 interfaces.
