4.7 V Zener — 500 mW, Axial, Active
The 1N6316/TR is a 4.7 V Zener diode from Microchip Technology, rated for 500 mW continuous power dissipation in the standard B, Axial through-hole package. Tolerance is ±5% on the nominal Zener voltage, and the maximum impedance (Zzt) is 17 Ohms at the test current — a typical figure for a 4.7 V device in this power class.
Leakage and forward characteristics
Reverse leakage is specified at 5 µA maximum with 1.5 V applied across the junction — a low leakage floor that keeps the diode from loading a high-impedance node in standby circuits. Forward voltage (Vf) is 1.4 V maximum at 1 A forward current, which defines the conduction loss if the diode is used in a bidirectional or series-pass role.
Active lifecycle — sourcing posture
Supplied in Tape & Reel (TR) packaging for automated through-hole insertion. The B, Axial body is the same footprint as industry-standard DO-35 and similar glass packages — no board change needed if the B, Axial outline matches the existing land pattern.
