Packaging

Type: Tape & Reel (TR) for automated pick-and-place

Package/case: SOD-123, 2 leads

Body material: molded plastic/epoxy

Lead finish: tin-plated leads (polarity band marks the cathode)

Size (approx): 2.8 mm × 1.8 mm × 1.1 mm overall envelope (standard SOD-123 footprint; check datasheet for exact dimensions and land pattern)

Pin configuration: 2 terminals; cathode identified by band, anode opposite end

Thermal characteristics: PD 500 mW at TA/TL per datasheet conditions; derate above 25°C; thermal resistance depends on PCB copper area and layout (see datasheet for guidelines)

Electrical properties summary: VZ 16 V nominal (±5%); Zzt 17 Ω max; VF 0.9 V max @ 10 mA; IR 100 nA max @ 12 V

Moisture Sensitivity: typically MSL 1 for SOD-123; confirm on datasheet on our page

Compliance: RoHS non-compliant (contact us for RoHS-compliant alternatives)
