Diodes Incorporated BAS16-7

Overview

BAS16-7 from Diodes Incorporated is a surface-mount fast-switching silicon switching diode in SOT23 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It serves as a general-purpose signal-level switching element in logic interface, clamping, and waveform shaping circuits across consumer, industrial, and communications equipment.

For engineers reviewing the BAS16-7 datasheet, BAS16-7 pinout, BAS16-7 application, or BAS16-7 equivalent, key selection criteria include its 4.0 ns t_RR, low 0.715 V forward voltage at 1 mA, 2.0 pF junction capacitance at 0 V, 2.0 A non-repetitive surge rating, and compatibility with automated SMT assembly on FR-4 PCBs.

Technical Context

The BAS16-7 operates as a planar epitaxial silicon PN junction diode optimized for high-speed digital switching. Its design emphasizes low stored charge and minimal minority-carrier lifetime to achieve sub-5 ns reverse recovery under 10 mA IF/IR conditions with 100 Ω load.

It functions in unidirectional current conduction mode with defined anode–cathode polarity, requiring correct orientation during placement. Thermal performance is specified for 357 °C/W junction-to-ambient resistance on standard 1-inch² 2 oz copper pad layout, supporting continuous operation from –55 °C to +150 °C.

FAQ

Is BAS16-7 pin-compatible with MMBD4148-7-F?

Yes - both devices share identical SOT23 pinout (anode on Pin 1, cathode on Pin 2, NC on Pin 3), identical mechanical dimensions, and fully overlapping electrical specifications including 75 V V_RRM, 4.0 ns t_RR, and 0.715 V V_F at 1 mA. They differ only in part marking, traceability, and qualification status.

What is the maximum junction temperature for continuous operation?

The BAS16-7 supports continuous operation with junction temperature ranging from –55 °C to +150 °C. At 25 °C ambient, its 357 °C/W thermal resistance allows ~200 mW dissipation before reaching 150 °C junction; derating follows the published power curve, dropping to 0 mW at 150 °C ambient.

Can BAS16-7 be used in place of 1N4148 through-hole diodes?

Yes, with PCB layout adaptation - BAS16-7 provides equivalent electrical performance (V_F, t_RR, V_RRM) in SOT23 format. It replaces 1N4148 in SMT designs where board space, automated assembly, and thermal performance on FR-4 are priorities, though mechanical mounting differs.

Does BAS16-7 meet halogen-free and green compound requirements?

Yes - BAS16-7 uses halogen- and antimony-free "Green" molding compound compliant with Diodes' definition: <900 ppm bromine, <900 ppm chlorine (<1500 ppm total Br+Cl), and <1000 ppm antimony compounds, certified per IEC 61249-2-21 and JEDEC J-STD-020.
