Notes:
1. The Electrical characteristics are measured after allowinh the device to stabilize for 20 sec. when mounted
with a 3/8” minimum lead length from the case.
2. Temperature Coefficient (dvz)
a. Izt= 7.5ma, T1= 25oC, T2= 125oC (1N5223B - 1N5242B)
b. Izt= rated Izt, T1= 25oC, T2= 125oC (1N5243B - 1N5261B)
