Series Resistor

276.0 Ω

Rs = (Vs - Vz) / (I_load + I_z_min) = (12 - 5.1) / (20mA + 5mA)

Nearest standard: 280 Ω

Voltage Regulation Output

5.10 V

Regulated output ≈ Vz = 5.1V (when Vs > Vz and I_z ≥ 5mA)

Resistor Power Dissipation

172.50 mW

Pr = (Vs - Vz)² / Rs

Use a resistor rated at least 0.35W for safety margin

Zener Power Dissipation

Under load:

127.50 mW

No load (worst case):

127.50 mW

Use a zener rated at least 0.26W
