Product details
Overview
BZT52B5V6 RHG from Taiwan Semiconductor is a surface-mount 5.6 V ±2% tolerance Zener diode in SOD-123F package, rated for 500 mW power dissipation, with dynamic impedance of 40 Ω at 5 mA test current and reverse leakage current ≤0.9 μA at 2.0 V, used for precision voltage regulation and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZT52B5V6 RHG datasheet, BZT52B5V6 RHG pinout, BZT52B5V6 RHG application, or BZT52B5V6 RHG equivalent, key selection criteria include zener voltage tolerance (±2%), thermal resistance (350°C/W), cathode-band polarity marking, moisture sensitivity level 1, and halogen-free compliance per IEC 61249-2-21.
Technical Context
The BZT52B5V6 RHG operates as a silicon planar junction Zener diode optimized for stable voltage reference and clamping in DC bias networks. It exhibits a nominal zener voltage of 5.60 V with tight ±2% tolerance, tested under 10 ms pulse conditions, and maintains low dynamic impedance (40 Ω) at IZT = 5 mA.
Its thermal design supports operation up to +150°C junction temperature, with derated power dissipation above 25°C ambient per Fig. 4 curve. The device uses matte tin (Sn) plating over nickel (Ni) underplate, qualified for high-temperature soldering (260°C/10s) and compliant with MIL-STD-202 Method 208.
