Product details
Overview
SMBG58AHE3/5B 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, 600 W peak pulse power (10/1000 µs), 93.6 V clamping voltage (VC) at 6.4 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG58AHE3/5B datasheet, SMBG58AHE3/5B pinout, SMBG58AHE3/5B application, or SMBG58AHE3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity with cathode band marking, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a fast-acting shunt protector that clamps transient voltages above its breakdown threshold to safeguard downstream ICs and MOSFETs. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and low incremental surge resistance, enabling consistent clamping across repetitive 0.01% duty-cycle surges.
The device is rated for 150 °C maximum junction temperature and exhibits 100 °C/W junction-to-ambient thermal resistance when mounted per recommended pad layout. Its 100 A IFSM rating supports high-energy 8.3 ms half-sine surge events, while MSL Level 1 moisture sensitivity allows uncompromised reflow at 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - Confirmed breakdown range ensuring reliable turn-on margin above VWM |
| VC @ IPPM | 93.6 V at 6.4 A - Clamped voltage during full 600 W surge, defining worst-case stress on protected circuit |
| PPPM | 600 W (10/1000 µs) - Peak transient energy handling capacity under standardized waveform |
| IFSM | 100 A (8.3 ms half-sine) - Surge current capability for non-repetitive line transients |
| TJ max. | 150 °C - Maximum junction temperature enabling operation in under-hood automotive environments |
| Leakage ID | <1.0 µA at 58 V - Minimal standby power loss and signal integrity impact in high-impedance circuits |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by molded band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |

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 rating), higher VC = 93.6 V (identical), different package (SMB vs. SMBG); slightly larger footprint | Compatible in board space-constrained designs where DO-214AA (SMB) pad layout exists; not drop-in due to mechanical mismatch | Select SMBJ58A-E3/5B only if legacy SMB footprint is fixed and thermal derating margin permits same power handling. |
| 1.5KE58A | Higher PPPM = 1500 W, axial DO-201AD package, VC = 95.0 V, no AEC-Q101 qualification, higher leakage (5.0 µA) | Used in non-automotive industrial power supplies where board-level mounting and vibration resistance are less critical | Choose 1.5KE58A for cost-sensitive, non-SMT applications needing higher surge headroom-but not for automotive or high-density PCBs. |
Compared with SMBJ58A-E3/5B and 1.5KE58A, SMBG58AHE3/5B delivers AEC-Q101 assurance, optimized SMT manufacturability in DO-215AA, and identical clamping performance in a smaller footprint-making it the preferred choice for new automotive and space-constrained industrial designs.

FAQ
What is the clamping voltage of SMBG58AHE3/5B at its rated peak pulse current?
The SMBG58AHE3/5B 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 defines the upper voltage limit imposed on protected circuitry during a full 600 W transient event and is confirmed in the Vishay Electrical Characteristics table for SMBG58AHE3/5B.
Is SMBG58AHE3/5B suitable for automotive applications?
Yes, SMBG58AHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments with operating junction temperatures up to 150 °C. Its RoHS-compliant HE3 suffix denotes AEC-Q101 qualification, and its construction meets requirements for vibration resistance, thermal cycling, and long-term reliability in engine control, body electronics, and infotainment systems.
What does the "HE3/5B" suffix indicate in SMBG58AHE3/5B?
The "HE3" suffix identifies the SMBG58AHE3/5B as RoHS-compliant and AEC-Q101 qualified, while "5B" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3200 units. This distinguishes it from "52" (7-inch reel, 750 units) and confirms compliance with automotive supply chain traceability and handling standards.
How does SMBG58AHE3/5B differ from bidirectional TVS diodes like SMBG58CA?
SMBG58AHE3/5B is unidirectional and features a cathode band for polarity-sensitive placement, whereas SMBG58CA is bidirectional with no polarity marking and symmetric clamping in both directions. The unidirectional SMBG58AHE3/5B offers lower leakage (<1.0 µA vs. ≤5.0 µA for CA types) and is intended for DC line protection, while SMBG58CA suits AC or floating signal line applications.
What is the thermal resistance of SMBG58AHE3/5B, and how does it affect layout design?
SMBG58AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperature under repeated surges, PCB layout must replicate this pad area and avoid excessive trace length or isolation-otherwise, thermal derating becomes necessary per Figure 2 in the Vishay datasheet.
