Product details
Overview
SMCG60CA-E3/57T 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 use.
For engineers reviewing the SMCG60CA-E3/57T datasheet, SMCG60CA-E3/57T pinout, SMCG60CA-E3/57T application, or SMCG60CA-E3/57T equivalent, this device is selected for high-energy surge immunity in automotive sensor interfaces, industrial I/O protection, and telecom line conditioning where bidirectional clamping, low clamping ratio, and MSL Level 1 reflow compatibility are critical.
Technical Context
The SMCG60CA-E3/57T operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
Designed for surface-mount automated assembly, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability requirements. Thermal resistance is 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads, supporting sustained 6.5 W power dissipation at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V nominal systems. |
| VBR min/max | 66.7 V / 73.7 V at IT = 1 mA - Tight breakdown window ensures predictable turn-on across temperature and lot variation. |
| VC @ IPPM | 96 V at 15.5 A - Clamping voltage during 10/1000 µs surge; yields clamping ratio of 1.6× VWM for effective downstream IC protection. |
| PPPM | 1500 W - Peak pulse power handling per IEEE C62.35; supports IEC 61000-4-5 Level 4 (4 kV) surge testing. |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and high-temperature industrial enclosures. |
| MSL Level | Level 1 (J-STD-020) - Allows unlimited floor life and standard 260 °C reflow profile without baking. |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount gull-wing package with 2 terminals, 7.11 mm × 6.22 mm footprint, 1.47 mm height, and UL 94 V-0 molding compound. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; symmetrical to cathode in bidirectional mode | Enables identical clamping behavior for positive and negative transients; no circuit polarity dependency. |
| Cathode | Current exit point in forward bias; symmetrical to anode in bidirectional mode | Terminal pair forms a voltage-triggered shunt path regardless of transient polarity; simplifies layout on differential or AC lines. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC performance in both directions - eliminates need for polarity-aware placement in sensor bridges or RS-485 lines. |
| Glass-passivated junction | Stable leakage (<1 µA at VWM) and VBR drift <5% over 1000 hrs HTOL - ensures long-term protection integrity in sealed modules. |
| Low incremental surge resistance | Dynamic impedance ≈ 6.2 Ω (calculated from ΔV/ΔI = (96 V − 60 V)/15.5 A) - minimizes voltage overshoot during fast-rising ESD events. |
| AEC-Q101 qualification | Validated for automotive Grade 2 (−40 °C to +105 °C ambient) and extended temperature operation up to TJ = +150 °C - suitable for ADAS camera modules and body control units. |
| MSL Level 1 compatibility | Rated for peak reflow temperature of 260 °C with no moisture sensitivity limitations - enables direct placement into high-volume SMT lines without dry-pack or baking. |

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) and PPPM (1500 W), but SMA (DO-214AC) package; higher RθJA (110 °C/W) and lower surge current rating (14.3 A). | Larger footprint (4.5 mm × 2.7 mm vs. 7.1 mm × 6.2 mm); less thermal mass for repeated surges. | Select SMAJ60CA only when board space is constrained and single-event surge duty dominates. |
| 1.5KE60CA | Higher power (1500 W), same VWM, but through-hole DO-201 package; 1000x higher unit weight and incompatible with SMT lines. | Requires wave solder or hand assembly; unsuitable for automated production or vibration-prone automotive mounts. | Choose 1.5KE60CA only for prototyping or legacy through-hole designs where rework flexibility outweighs production efficiency. |
Compared with SMAJ60CA and 1.5KE60CA, SMCG60CA-E3/57T delivers superior thermal performance (75 °C/W vs. 110 °C/W), AEC-Q101 qualification absent in both alternatives, and optimized gull-wing geometry for high-yield SMT placement-making it the preferred choice for volume automotive and industrial applications requiring reliability and process compatibility.

FAQ
What is the clamping voltage of SMCG60CA-E3/57T at its rated peak pulse current?
The SMCG60CA-E3/57T has a maximum clamping voltage (VC) of 96 V at its specified peak pulse current (IPPM) of 15.5 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and reflects the voltage seen by protected circuitry during worst-case surge conditions, ensuring downstream ICs remain within safe operating limits.
Is SMCG60CA-E3/57T suitable for automotive applications?
Yes, SMCG60CA-E3/57T is AEC-Q101 qualified and rated for junction temperatures up to +150 °C, making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor modules. Its bidirectional symmetry, low leakage (<1 µA at 60 V), and MSL Level 1 reflow compatibility further support under-hood and module-integrated deployments.
How does the SMCG60CA-E3/57T differ from unidirectional variants like SMCG60A-E3/57T?
The SMCG60CA-E3/57T is bidirectional with symmetrical electrical characteristics in both polarities, while SMCG60A-E3/57T is unidirectional and features a cathode band marking. The CA version clamps equally on positive and negative transients, enabling use on AC-coupled or floating lines; the A version requires correct polarity orientation and offers slightly higher IFSM (200 A) but lacks reverse-direction protection.
What is the thermal resistance of SMCG60CA-E3/57T, and how does it affect PCB layout?
SMCG60CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperature under 6.5 W continuous dissipation, designers must allocate sufficient copper area and consider airflow; reducing pad size increases RθJA and risks thermal runaway during repeated surges.
Does SMCG60CA-E3/57T require special handling or packaging due to moisture sensitivity?
No-SMCG60CA-E3/57T is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be processed using standard 260 °C lead-free reflow profiles without pre-baking. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the UL 94 V-0 molding compound resists delamination during thermal cycling.
