SZ5520 Pinout – DO-214AC (SMA) Package

Note: The SZ5520 is a two-terminal surface-mount Zener diode in DO-214AC (SMA) package. This is a discrete diode component, not a multi-pin IC.

Notes

• Package: DO-214AC (SMA) — a two-terminal surface-mount package for discrete diodes.
• Zener Voltage (SZ5520): 20 V nominal at I_ZT = 37 mA.
• Cathode Identification: The color band on the diode body denotes the cathode end (Pin 2).
• Maximum DC Zener Current (I_ZM): 135 mA.
• Maximum Power Dissipation (P_D): 3 W at T_L = 75 °C.
• Reverse Leakage Current (I_R): 0.5 mA maximum at V_R = 15.2 V.
• No pin diagram was provided in the source material; pin numbering follows standard DO-214AC convention (Anode = 1, Cathode = 2).
