BAS70LP-7B

BAS70LP-7B is a BAS70 family high-speed Schottky barrier diode used for fast switching with a low forward voltage drop. It’s a small-signal, surface-mount diode (typical in compact packages) tailored for RF and digital circuits where fast response and low VF matter. Key benefits include a very low forward drop (around 0.2–0.3 V at light currents), fast switching, and low junction capacitance suitable for high-frequency operation. Common uses: signal rectification, clamping, detectors, level shifting, and input protection in logic/RF circuits. Exact electrical ratings (reverse voltage, forward current, surge, capacitance) depend on the specific variant; consult the datasheet for VR, IF, VF, Crss, and temperature range. The -7B suffix denotes a particular variant/version within the BAS70LP family. In a project, ensure the diode’s reverse-voltage rating exceeds your supply and orient it for the intended clamp/rectification path.

Infineon BAS70LP-7B equivalents include Onsemi MMBAV99LT1G (BAV99), Vishay MMBAV99, STMicro STBAV99, Central Semiconductor BAS70W and Diodes Inc. BAV99W. All are SOT-23 dual-series high-speed switching diodes with similar 70 V reverse rating, 200 mA forward current and low capacitance.

Here are typical features of BAS70LP-7B:
- Dual small-signal fast-switching diodes in a compact leadless SMD package
- Suitable for high-speed switching, RF front-end, detector, and protection/clamping roles
- Low forward voltage drop and fast switching performance
- Very low junction capacitance for minimal RF loading
- High reverse-voltage rating (per BAS70 family; exact Vr specified in datasheet)
- Low leakage current in reverse direction
- RoHS-compliant, tape-and-reel packaging; reflow compatible
- Wide operating temperature range (typical industrial range)
Note: exact electrical specs (Vr, If, IFRM, junction capacitance, etc.) vary by variant. Please consult the official datasheet for the precise values for BAS70LP-7B.

- Pin count: 3 pins (SOT-23 package)
- Function: Dual Schottky barrier diode in one package; two diodes share a common terminal (used for fast switching/rectification). The exact common-terminal polarity (common anode or common cathode) is specified in the BAS70LP-7B datasheet.
