Electrical characteristics

Limits as printed in the datasheet (page.json metadata.characteristics carries them as data).

Parameter Symbol Min Typ Max Unit Conditions Page
Zener voltage (nominal) at IZT VZ 10 V at IZT = 125 mA 2
Zener voltage tolerance (B suffix, ±5%) VZ -5 5 % suffix B = ±5% tolerance; JEDEC type alone is ±10% 3
Maximum zener impedance at IZT ZZT 2 Ω @ IZT = 125 mA 2
Maximum zener impedance at IZK ZZK 125 Ω @ IZK = 1 mA 2
Maximum reverse leakage current IR 5 µA at VR = 7.6 V 2
DC power dissipation PD 5 W TL = 75, measured at zero lead length (Fig.1) 1
Derating above TL = 75 PD 40 mW derate above 75 (NOTE 1) 1
Storage temperature range Ts -55 150 °C 1
Junction temperature TJ -55 150 °C 1
