Product details
Overview
SMBG5.0A-M3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, rated for 5.0 V stand-off voltage, 6.4–7.07 V breakdown at 10 mA, 600 W peak pulse power (10/1000 μs), and clamping to 9.2 V at 65.2 A surge current. It protects ICs and MOSFETs against inductive switching transients in automotive and industrial power rails.
For engineers reviewing the SMBG5.0A-M3/5B datasheet, SMBG5.0A-M3/5B pinout, SMBG5.0A-M3/5B application, or SMBG5.0A-M3/5B equivalent, key selection criteria include unidirectional polarity, 800 μA max reverse leakage at 5.0 V, AEC-Q101 qualification, halogen-free RoHS compliance, and MSL Level 1 reflow capability up to 260 °C.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, activating when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable avalanche behavior, low incremental surge resistance enables effective energy diversion, and fast response time (<1 ns) limits voltage overshoot during ESD or lightning-induced surges.
The SMBG5.0A-M3/5B is designed for surface-mount placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, supporting repetitive 0.01% duty cycle pulses. Thermal resistance is 100 °C/W junction-to-ambient (typical) and 20 °C/W junction-to-lead, enabling reliable operation up to 150 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-M3/5B | Same SMBG package, identical VWM/VBR/VC, but rated for 600 W with 8.3 ms half-sine surge (IFSM = 100 A); no AEC-Q101 qualification | Not approved for automotive safety-critical systems; suitable for industrial/commercial where qualification not mandated | Select SMBJ5.0A-M3/5B if AEC-Q101 is unnecessary and higher IFSM margin is prioritized |
| SMAJ5.0A-M3/5B | Smaller SMA (DO-214AC) package, same electrical specs but lower PPPM (400 W), higher thermal resistance (RθJA = 150 °C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or high-repetition surge environments | Choose SMAJ5.0A-M3/5B only for space-constrained consumer designs with benign surge profiles |
Compared with SMBJ5.0A-M3/5B and SMAJ5.0A-M3/5B, the SMBG5.0A-M3/5B uniquely combines AEC-Q101 qualification, 600 W 10/1000 μs capability, and SMBG thermal performance-making it the only option qualified for under-hood automotive power rail protection where reliability and surge margin are non-negotiable.

FAQ
What is the clamping voltage of SMBG5.0A-M3/5B at its rated peak pulse current?
The SMBG5.0A-M3/5B clamps to 9.2 V at its specified peak pulse current of 65.2 A under a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and defines the maximum voltage imposed on protected circuitry during surge events. The SMBG5.0A-M3/5B maintains this clamping performance across its operational temperature range and after repeated surges within duty cycle limits.
Is SMBG5.0A-M3/5B suitable for automotive applications?
Yes, SMBG5.0A-M3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units and body electronics subject to ISO 7637-2 load-dump and jump-start transients. Its halogen-free M3 construction, MSL Level 1 reflow rating, and 150 °C junction temperature capability make SMBG5.0A-M3/5B appropriate for under-hood deployment where thermal and reliability demands are most stringent.
How does the M3 suffix affect the SMBG5.0A-M3/5B material composition?
The M3 suffix on SMBG5.0A-M3/5B indicates halogen-free, RoHS-compliant construction meeting IPC-1752A material declaration standards. Unlike E3-suffix variants, M3 uses bromine- and chlorine-free flame retardants in the molding compound and conforms to JEDEC JESD201 Class 2 whisker resistance requirements-ensuring long-term solder joint integrity in high-reliability applications.
What is the reverse leakage current specification for SMBG5.0A-M3/5B at its stand-off voltage?
At its 5.0 V stand-off voltage (VWM), the SMBG5.0A-M3/5B exhibits a maximum reverse leakage current (ID) of 800 μA at 25 °C. This parameter is critical for low-power sensor rails and battery-backed circuits, where excessive leakage could drain reserves or shift reference levels; the SMBG5.0A-M3/5B's leakage remains well within acceptable limits for such applications.
Can SMBG5.0A-M3/5B be used in bidirectional configurations?
No, SMBG5.0A-M3/5B is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., SMBG5.0CA). Using SMBG5.0A-M3/5B in reverse-biased configurations risks permanent breakdown, as it lacks symmetrical avalanche characteristics. For AC-coupled or dual-polarity signal lines, the SMBG5.0CA-M3/5B must be selected instead.
