3.0 Watts Surface Mount Silicon Zener Diode

Product catalog summary

Overview: This document provides technical specifications for the 1SMB5926 to 1SMB5956 series of 3.0 Watts Surface Mount Silicon Zener Diodes, designed for surface-mounted applications to optimize board space. The diodes are housed in a low-profile SMB/DO-214AA package with built-in strain relief and glass passivated junctions.

Mechanical Specifications:

Case: Molded plastic over passivated junction
Terminals: Pure tin plated, lead-free, solderable per MIL-STD-750, Method 2026
Polarity: Color band denotes positive end (cathode)
Standard packaging: 12mm tape (EIA-481)
Weight: 0.002 ounces (0.064 grams)

Features:

Low inductance
High temperature soldering guaranteed at 260°C for 10 seconds at terminals
Plastic package with Underwriters Laboratory Flammability Classification 94V-0

Maximum Ratings and Electrical Characteristics:

DC Power Dissipation at TL=75°C: 3.0 Watts
Thermal Resistance from Junction-to-Lead: 25°C/W
Thermal Resistance from Junction-to-Ambient: 226°C/W
Operating and Storage Temperature Range: -65 to +150°C

Electrical Characteristics: The document lists detailed electrical characteristics for each diode in the series, including Zener voltage range, Zener impedance, and leakage current. Each diode is marked with a specific code and has a tolerance of ±5%.

Graphs and Figures: The document includes several figures illustrating:

Steady state power derating
Maximum surge power
Zener voltage characteristics
Capacitance and pulse rating curves

Notes:

Nominal Zener voltage is measured with the device junction in thermal equilibrium at 25°C.
Zener impedance is derived by dividing the AC voltage drop across the device by the AC current applied.
