Product details
Overview
SMBG58CA-E3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 93.6 V at 6.4 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG58CA-E3/5B datasheet, SMBG58CA-E3/5B pinout, SMBG58CA-E3/5B application, or SMBG58CA-E3/5B equivalent, key selection criteria include bidirectional surge clamping performance, low leakage (<1 µA at 58 V), thermal resistance (RθJA = 100 °C/W), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions, enabling protection of AC signal lines or differential buses without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the low incremental surge resistance minimizes clamping overshoot during high-current transients.
The device is rated for repetitive 10/1000 µs surges at 0.01% duty cycle and supports peak forward surge current up to 100 A (8.3 ms half-sine) in unidirectional configurations - though SMBG58CA-E3/5B is bidirectional and does not specify IFSM. Junction temperature range spans −55 °C to +150 °C, supporting under-hood automotive and industrial environments.

IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp (CJ ≈ 100 pF typical at 0 V) placed directly at USB connector to minimize stub length and preserve signal rise/fall times. Use Value: Provides <1 µA leakage at 58 V stand-off, avoiding false disconnect detection while clamping ESD to <93.6 V to protect USB PHY transceivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | Same VWM (58 V), identical VBR range (64.4–71.2 V), but lower PPPM = 600 W (same rating), different package: SMB (DO-214AA), slightly larger footprint and higher RθJA (110 °C/W vs. 100 °C/W). | Less suitable for space-constrained automotive modules; requires pad layout revision due to DO-214AA outline. | Select SMBJ58CA only if existing design uses SMB footprint and thermal margin permits higher junction temperature rise. |
| SMCJ58CA | Same electrical specs (VWM, VBR, VC, PPPM), but larger SMC (DO-214AB) package with higher surge current rating (IPPM = 10.3 A vs. 6.4 A) and lower RθJA (60 °C/W). | Better suited for high-energy industrial surges; incompatible with SMBG land pattern due to wider body and longer leads. | Choose SMCJ58CA when system-level surge testing exceeds 600 W or when board layout allows larger 7.1 mm × 6.2 mm footprint. |

FAQ
What is the clamping voltage of SMBG58CA-E3/5B at its rated peak pulse current?
The SMBG58CA-E3/5B has a maximum clamping voltage (VC) of 93.6 V at its specified peak pulse current (IPPM) of 6.4 A, measured under the standard 10/1000 µs waveform. This value is guaranteed across the operating temperature range and ensures downstream components remain within safe voltage limits during surge events. The SMBG58CA-E3/5B achieves this clamping performance while maintaining low dynamic impedance, which is essential for effective transient energy diversion.
Is SMBG58CA-E3/5B suitable for automotive applications?
Yes, SMBG58CA-E3/5B 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 glass-passivated junction ensure robustness against thermal cycling, humidity, and mechanical stress. The SMBG58CA-E3/5B meets requirements for engine control units, body control modules, and ADAS sensor interfaces where reliability under harsh conditions is mandatory.
Does SMBG58CA-E3/5B have polarity markings on the package?
No, SMBG58CA-E3/5B does not feature polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants that use a cathode band to indicate polarity, bidirectional types such as SMBG58CA-E3/5B have symmetrical electrical behavior in both directions and therefore omit external markings. This design simplifies layout for AC-coupled or differential signal protection where polarity independence is required.
What is the maximum reverse leakage current for SMBG58CA-E3/5B at its stand-off voltage?
The SMBG58CA-E3/5B exhibits a maximum reverse leakage current (ID) of 1 µA at its rated stand-off voltage (VWM) of 58 V and ambient temperature of 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and extends battery life in always-on monitoring systems. The SMBG58CA-E3/5B maintains this specification across its full operating temperature range, with leakage increasing predictably per datasheet derating curves.
What package type does SMBG58CA-E3/5B use, and what are its key mechanical features?
SMBG58CA-E3/5B uses the SMBG (DO-215AA) package - a low-profile, gull-wing surface-mount outline measuring 4.57 mm × 3.94 mm with 1.96 mm height. Key features include matte tin-plated leads compliant with J-STD-002, UL 94 V-0 molding compound, and optimized thermal pad layout (0.2″ × 0.2″ copper per terminal). The SMBG58CA-E3/5B's compact size and MSL Level 1 rating enable direct integration into high-density automotive and industrial PCBs without reflow complications.
