Product details
Overview
SZMM5Z6V2ST5G from onsemi is a 6.2 V ±4.8% tolerance Zener diode in SOD-523 package, rated for 500 mW steady-state power dissipation at 25 °C, with 100 Ω max Zener impedance at 5 mA test current and 185 pF max capacitance at 0 V/1 MHz - used for precision voltage reference and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the SZMM5Z6V2ST5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±4.8%), thermal resistance (250 °C/W), ESD rating (>16 kV HBM), AEC-Q101 qualification, and SOD-523 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference by maintaining a stable reverse breakdown voltage across its cathode-anode terminals under controlled current conditions. It delivers tight regulation (6.06 V to 6.33 V at IZT = 5 mA) with low dynamic impedance (100 Ω max) and minimal temperature coefficient (+0.4 mV/°C).
Designed for surface-mount use in ultra-compact applications, it features Pb-free matte tin plating, MSL 1 reflow capability (260 °C peak), and Class 3 ESD robustness (>16 kV HBM). Its 1.20 mm × 0.80 mm × 0.70 mm outline enables integration into cellular handsets and wearable devices where board area is constrained.
