Product details

Overview

SMBJ10D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 11.3 V minimum breakdown voltage (V_BR), 16.7 V maximum clamping voltage (V_C) at 35.9 A peak pulse current, and 600 W peak pulse power rating under 10/1000 μs waveform - deployed for overvoltage protection of ICs and MOSFETs in industrial power supplies and sensor interfaces.

For engineers reviewing the SMBJ10D-M3/H datasheet, SMBJ10D-M3/H pinout, SMBJ10D-M3/H application, or SMBJ10D-M3/H equivalent, key selection criteria include unidirectional polarity, 10 V stand-off voltage (V_WM), ±3.5 % V_BR tolerance, low leakage (<2.0 μA at V_WM), and M3-grade halogen-free RoHS-compliant construction suitable for automated SMT assembly.

Technical Context

This TVS diode operates as a clamping device that remains high-impedance below 10 V reverse stand-off voltage and rapidly transitions to low-impedance conduction above 11.3 V breakdown threshold, limiting transient-induced voltage excursions to ≤16.7 V at 35.9 A. Its junction-to-ambient thermal resistance is 125 °C/W on standard PCB pad layout.

The SMBJ10D-M3/H complies with ANSI/IEEE C62.35 surge standards, meets UL 497B recognition (QVGQ2), and is rated for operation from –55 °C to +150 °C junction temperature. It is not intended for continuous forward conduction or rectification duty.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR (min)	11.3 V - ensures reliable triggering above 10 V system operating voltage
V_C (max) at I_PPM	16.7 V - limits worst-case transient voltage seen by protected downstream IC
I_PPM	35.9 A - peak surge current capability under 10/1000 μs waveform
V_WM	10 V - maximum continuous reverse operating voltage without significant leakage
I_D (max) at V_WM	2.0 μA - ultra-low leakage preserves signal integrity in high-impedance circuits
P_PPM	600 W - robust energy absorption for lightning-induced or inductive-switching transients
T_J max	+150 °C - supports operation in thermally demanding industrial environments

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ10A-M3/H	Same V_WM (10 V), identical package and power rating, but ±5 % V_BR tolerance (vs. ±3.5 %)	Less precise clamping threshold; acceptable where tighter V_BR control is not required	Select SMBJ10A-M3/H only if design tolerates wider V_BR spread and cost reduction is prioritized
SMCJ10A	Higher 1500 W P_PPM, larger SMC (DO-214AB) package, same V_WM/V_BR range	Requires PCB area increase; used where higher surge immunity is mandated (e.g., outdoor equipment)	Choose SMCJ10A only when 600 W is insufficient and board space allows larger footprint

Compared with SMBJ10A-M3/H and SMCJ10A, the SMBJ10D-M3/H delivers tighter V_BR control for precision clamping and optimal fit in space-constrained SMB layouts, while maintaining full compliance with industrial surge immunity requirements without over-specifying power or size.

FAQ

What is the breakdown voltage range for SMBJ10D-M3/H?

The SMBJ10D-M3/H has a guaranteed breakdown voltage (V_BR) range of 11.3 V to 12.1 V at 1.0 mA test current, reflecting its ±3.5 % tolerance specification. This tight V_BR window ensures predictable clamping onset relative to its 10 V stand-off voltage, making SMBJ10D-M3/H suitable for protecting 12 V nominal systems where overvoltage margin must be tightly controlled.

Is SMBJ10D-M3/H unidirectional or bidirectional?

SMBJ10D-M3/H is a unidirectional TVS diode, indicated by the "D" suffix (as opposed to "CD" for bidirectional). It features a cathode band and conducts only in reverse breakdown - ideal for DC rail protection where polarity is fixed. Bidirectional variants like SMBJ10CD-M3/H would be required for AC-coupled or differential signal lines.

What does the "-M3/H" suffix mean in SMBJ10D-M3/H?

The "-M3" denotes Vishay's halogen-free, RoHS-compliant, industrial-grade construction with JESD 201 Class 2 whisker resistance; "/H" specifies packaging in 7″ plastic tape and reel (750 units per reel). This suffix confirms SMBJ10D-M3/H meets stringent environmental and manufacturability requirements for high-volume SMT assembly without lead-free reflow concerns.

Can SMBJ10D-M3/H replace SMBJ10A-M3/H in an existing design?

Yes, SMBJ10D-M3/H can replace SMBJ10A-M3/H in most cases, as both share identical package (SMB), V_WM (10 V), P_PPM (600 W), and thermal ratings. The key difference is tighter ±3.5 % V_BR tolerance in SMBJ10D-M3/H versus ±5 % in SMBJ10A-M3/H - offering improved clamping consistency without layout or schematic changes.

What is the maximum clamping voltage of SMBJ10D-M3/H at rated surge current?

The SMBJ10D-M3/H has a maximum clamping voltage (V_C) of 16.7 V at its rated peak pulse current (I_PPM) of 35.9 A, measured under the standardized 10/1000 μs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events, directly informing downstream IC voltage stress margins.
