Product details
Overview
SMBG58A-E3/5B from Vishay General Semiconductor is a unidirectional 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, 93.6 V maximum clamping voltage (VC) at 6.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the SMBG58A-E3/5B datasheet, SMBG58A-E3/5B pinout, SMBG58A-E3/5B application, or SMBG58A-E3/5B equivalent, key selection criteria include clamping performance under 6.4 A surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification for automotive use, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VBR, it avalanches to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the low incremental surge resistance enables tight clamping during fast transients.
Thermal design relies on RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), supporting operation from –55 °C to +150 °C junction temperature. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101, confirming suitability for under-hood automotive environments without derating below 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - defines reliable avalanche onset window for predictable protection threshold |
| VC @ IPPM | 93.6 V at 6.4 A - clamping voltage during full 600 W transient, limiting stress on protected ICs |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform, duty cycle ≤0.01 % |
| ID @ VWM | ≤1.0 µA - ultra-low reverse leakage preserves signal integrity in high-impedance circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-E3/5B | Same VWM (58 V), but lower PPPM = 600 W (same), higher VC = 93.6 V (identical), identical SMB package and AEC-Q101 qualification | No functional difference; SMBJ and SMBG share same electrical specs for 58 V grade per Vishay documentation | Select SMBG58A-E3/5B when DO-215AA mechanical form factor is required; SMBJ58A-E3/5B uses DO-214AB (SMB) with slightly different pad layout |
| 1.5SMC58A | Higher VC = 96.8 V at 6.2 A, same VWM/VBR, but larger SMC (DO-214AB) package and no AEC-Q101 qualification | Lacks automotive qualification; thermal resistance higher (RθJA ≈ 125 °C/W), limiting high-reliability deployments | Use only in non-automotive industrial applications where AEC-Q101 is not mandated and board space allows larger SMC footprint |
Compared with SMBJ58A-E3/5B and 1.5SMC58A, SMBG58A-E3/5B offers identical clamping performance and automotive qualification in the smaller DO-215AA outline, enabling higher board density and certified under-hood use without compromising surge margin.

FAQ
What is the clamping voltage of SMBG58A-E3/5B at its rated peak pulse current?
The SMBG58A-E3/5B has a maximum clamping voltage (VC) of 93.6 V at 6.4 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 and ensures protected downstream components experience limited overvoltage stress during standardized surge events. The SMBG58A-E3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG58A-E3/5B qualified for automotive applications?
Yes, SMBG58A-E3/5B is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 09-Jan-2024 (Document Number: 88456). This qualification covers stress tests including temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - validating its use in engine control units, body electronics, and other under-hood automotive systems. The SMBG58A-E3/5B carries the HE3 suffix variant for full AEC-Q101 compliance.
What does the '-E3/5B' suffix indicate in SMBG58A-E3/5B?
The '-E3' denotes RoHS-compliant, industrial-grade matte tin plating per JESD 201 Class 2 whisker testing, while '/5B' specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format supports high-volume SMT placement and is distinct from the '/52' variant (7-inch reel, 750 units). The SMBG58A-E3/5B is not halogen-free; that requires the '-M3' or '-HM3' suffix variants.
How does SMBG58A-E3/5B differ from bidirectional TVS diodes like SMBG58CA?
SMBG58A-E3/5B is unidirectional and features a cathode band for polarity identification, enabling asymmetric protection where only negative transients or forward conduction must be blocked. In contrast, SMBG58CA is bidirectional with no polarity marking and symmetric clamping in both directions - used for AC lines or differential signal pairs. Electrical parameters (VWM, VBR, VC) are nearly identical, but SMBG58A-E3/5B cannot replace SMBG58CA in AC-coupled applications without circuit redesign.
What is the maximum operating temperature for SMBG58A-E3/5B?
The SMBG58A-E3/5B has a specified operating junction and storage temperature range of –55 °C to +150 °C, per Vishay's datasheet. Its thermal resistance values (RθJA = 100 °C/W typ., RθJL = 20 °C/W typ.) allow sustained operation at full 600 W pulse rating only when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. Derating is required above 25 °C ambient per Figure 2 in the SMBG5.0A–SMBG188CA datasheet.
