DDZ43-7 Description

Short technical summary and product information.

The DDZ43-7 is a Zener diode from Diodes Incorporated designed for voltage regulation and protection applications. It features a nominal Zener voltage of 43V with a tolerance of ±2%, ensuring precise voltage clamping. The device can dissipate up to 500mW of power (note: datasheet specifies 470mW; verification recommended).

 

Electrical characteristics include a maximum Zener impedance of 90Ω, a reverse leakage current of 50nA at 33V, and a forward voltage of 900mV at 10mA. The diode operates over a wide temperature range from -65°C to 150°C, making it suitable for harsh environments.

 

The DDZ43-7 is housed in a compact SOD-123 surface mount package, ideal for space-constrained designs. It is RoHS3 compliant (unverified), with MSL 1 and REACH unaffected status.
