Product details
Overview
SMCG58CA-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 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), clamping voltage of 93 V at 16 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG58CA-E3/57T datasheet, SMCG58CA-E3/57T pinout, SMCG58CA-E3/57T application, or SMCG58CA-E3/57T equivalent, key selection criteria include bidirectional clamping behavior, 1500 W surge capability under 10/1000 µs waveform, low incremental surge resistance, UL 94 V-0 molding compound, and compatibility with automated SMT placement on industrial and automotive PCBs.
Technical Context
This device operates as a voltage-clamped shunt protector, responding within picoseconds to transients exceeding its VWM. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the bidirectional symmetry enables protection on AC-coupled or floating lines without polarity concerns.
The SMCG58CA-E3/57T delivers 1500 W peak pulse power dissipation with a 10/1000 µs waveform, supported by a thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead). It maintains full functionality across –55 °C to +150 °C operating junction temperature, meeting MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse working voltage before clamping begins |
| VBR min/max | 64.4 V / 71.2 V - Breakdown occurs within this range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | 93 V - Clamped voltage at 16 A peak pulse current, limiting downstream stress |
| PPPM | 1500 W - Peak surge energy handling per 10/1000 µs waveform, critical for ISO 7637-2/IEC 61000-4-5 compliance |
| ID @ VWM | <1.0 µA - Ultra-low leakage preserves signal integrity in high-impedance sensor or communication lines |
| TJ max | +150 °C - Enables deployment in under-hood automotive environments and high-power industrial enclosures |

Applications
| Automotive CAN Bus Protection | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L differential pair against load dump, jump-start, and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Shunt TVS placed directly at connector interface to clamp transients before they reach CAN transceiver. Use Value: Maintains CAN signal integrity with 93 V clamping at 16 A, preventing transceiver latch-up or damage during ISO 7637-2 Pulse 5a. | Use Scenario: Safeguarding analog outputs (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors in factory automation systems. IC Role / Device Role / Timing Role: Bidirectional clamping element on sensor output line to absorb inductive switching spikes from nearby solenoids or motors. Use Value: Sub-1 µA leakage at 58 V VWM avoids loading precision analog signals; 1500 W rating handles repetitive 100 V/10 A surges per IEC 61000-4-4. |
| Telecom Line Interface | Consumer USB Port ESD Protection |
Use Scenario: Protecting RS-485 transceivers in base station backhaul links exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary surge suppression stage on differential data lines, upstream of secondary filtering. Use Value: Symmetrical bidirectional response ensures equal clamping on both A/B lines; DO-215AB package allows compact dual-line layout with minimal parasitic inductance. | Use Scenario: Adding system-level ESD immunity to USB 2.0 D+/D− lines in smart home hubs and portable media devices. IC Role / Device Role / Timing Role: Fast-response shunt protector placed adjacent to USB connector to divert ±15 kV contact discharge per IEC 61000-4-2. Use Value: 93 V clamping voltage provides safe margin below USB PHY's absolute maximum ratings; RoHS-compliant E3 suffix meets consumer regulatory requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58CA | Lower PPPM (400 W), SMA (DO-214AC) package, higher RθJA (110 °C/W) | Suitable for lower-energy transients; less effective in high-temperature or high-surge environments | Select when cost or board space is prioritized over 1500 W surge headroom |
| SMCJ58CA | Same PPPM (1500 W), larger SMC (DO-214AB) package, higher thermal mass, RθJA = 50 °C/W | Better thermal performance in sustained surge conditions but requires ~2× PCB area | Select when long-duration transients or elevated ambient temperatures dominate design constraints |
Compared with SMAJ58CA and SMCJ58CA, the SMCG58CA-E3/57T delivers identical 1500 W surge capability in a 30 % smaller footprint than SMCJ and superior thermal resistance versus SMAJ-making it optimal for space-constrained automotive and industrial modules requiring AEC-Q101 validation.

FAQ
What does the "CA" suffix indicate in SMCG58CA-E3/57T?
The "CA" suffix denotes a bidirectional configuration - meaning the SMCG58CA-E3/57T provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics for positive and negative surges. This eliminates the need for polarity-aware placement and supports AC-coupled or floating signal lines, unlike unidirectional variants (e.g., SMCG58A) that require cathode orientation.
Is SMCG58CA-E3/57T suitable for automotive applications?
Yes, SMCG58CA-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use. It undergoes stress testing including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), and its DO-215AB package meets MSL Level 1 and JESD201 Class 2 whisker resistance - making SMCG58CA-E3/57T appropriate for engine control units, body electronics, and ADAS sensor interfaces.
How does the clamping voltage of SMCG58CA-E3/57T compare to its breakdown voltage?
The SMCG58CA-E3/57T has a VBR range of 64.4–71.2 V at 1 mA and clamps at 93 V when subjected to its rated 16 A peak pulse current (IPPM). This 22–29 V differential reflects its low incremental surge resistance, ensuring predictable voltage limiting during real-world transients - a critical parameter for protecting downstream ICs with 100 V absolute maximum ratings.
What is the significance of the "E3/57T" suffix in SMCG58CA-E3/57T?
The "E3" indicates RoHS-compliant, industrial-grade construction with matte tin-plated leads; "57T" specifies packaging in 7-inch plastic tape-and-reel format containing 850 units. This configuration ensures compatibility with standard SMT feeders and supports high-volume automated assembly - a key requirement for production runs of SMCG58CA-E3/57T in automotive and industrial manufacturing.
Can SMCG58CA-E3/57T be used in place of a unidirectional TVS like SMCG58A?
No - SMCG58CA-E3/57T is bidirectional and lacks polarity marking, whereas SMCG58A is unidirectional with a cathode band. Substituting them requires circuit review: SMCG58CA-E3/57T may be used on AC or floating lines, but will not provide correct forward conduction in DC-biased unidirectional paths. Always verify biasing, grounding, and signal topology before replacing SMCG58A with SMCG58CA-E3/57T.
