Detailed Description

High-speed small-signal switching diode from Nexperia BAS21 family. Surface-mount SOD-323 package (manufacturer case code 675). Designed for fast, clean switching at high reverse voltages with low leakage and low junction capacitance. Suitable for compact, high-density boards needing reliable signal switching and protection.

Key Features

High reverse voltage rating typically up to 200 V

Fast switching time typically tens of nanoseconds

Low junction capacitance around a few picofarads for minimal signal distortion

Low reverse leakage for stable performance across temperature

Small SOD-323 footprint for space-constrained designs

RoHS compliant and halogen-free molding compound

Broad availability and stable production from Nexperia

Key Advantages

Simple, robust solution for signal switching and clamping

Consistent performance over temperature with low leakage

Saves PCB space while maintaining high voltage capability

Easy to source and drop-in across many BAS21-class designs

Supported by a trusted brand with strong quality controls

Cost-effective for high-volume production

Packaging

Package type SOD-323 (case code 675), 2-pin SMT diode

Body material epoxy molding compound, RoHS compliant and halogen-free

Leadframe copper alloy with tin plating for good solderability

Approximate size SOD-323 about 2.5 mm x 1.3 mm x 1.1 mm (verify exacts in datasheet)

Pin configuration 1 Anode, 2 Cathode; polarity mark indicates cathode

Thermal characteristics typical junction temperature up to 150°C; storage -65°C to +150°C; typical thermal resistance RthJA in the several hundred K/W range depending on PCB copper area

Electrical properties typical for BAS21 family reverse voltage VR up to 200 V, continuous forward current IF around 200–250 mA, very low capacitance ~2 pF, fast reverse recovery typically ~50 ns, low reverse leakage in the nA range at room temperature

Shipment format tape-and-reel per EIA-481 standards; common 7-inch and 13-inch reels available; moisture sensitivity typically MSL 1 for plastic SMT diodes
