BZT52C10T-7

The BZT52C10T-7 is a 10V Zener diode from Diodes Incorporated, designed for low-power voltage regulation and protection in surface mount applications. It is rated for a maximum power dissipation of 300mW and offers a nominal Zener voltage of 10V with a tolerance of ±6%. The forward voltage is typically 900mV at 10mA forward current, and the reverse leakage current is limited to 200nA at 7V reverse voltage. The maximum impedance (Zzt) is 20Ω.

The device is housed in a compact SOD-523 (SC-79) surface mount package, making it suitable for space-constrained designs. The junction-to-ambient thermal resistance is 417°C/W, and the junction-to-case thermal resistance is 160°C/W. The operating temperature range spans from -65°C to 150°C, accommodating a wide variety of environments. The package is molded from green plastic with UL 94V-0 flammability rating, and the terminals are matte tin annealed over Alloy 42 leadframe, solderable per MIL-STD-202, Method 208.

Environmental compliance is robust: the BZT52C10T-7 is RoHS3 compliant, lead-free, and halogen- and antimony-free (green device). It is also qualified to AEC-Q101 standards for high reliability, making it suitable for automotive applications. The moisture sensitivity level is MSL Level 1 per J-STD-020, allowing unlimited floor life before soldering.

Typical applications include voltage regulation, overvoltage protection, and voltage clamping in low-power circuits such as portable electronics, power supplies, and signal conditioning units.
