ITEM SPECIFICS
Brand: Motorola
MPN: 1N3208
Model: 1N3208
Type: Standard Recovery Rectifier Diode
Package: DO-5 (DO-203AB) Stud Mount
Polarity: Standard (Cathode to Case / Stud)
Max Repetitive Reverse Voltage (VRRM): 50 V
Average Forward Current (IF(AV)): 15 A
Peak Surge Current (IFSM): 250 A
Max Forward Voltage: 1.5 V
Cross Reference: ECG5940 / NTE5940
Date Code: 7244
Mounting Hardware: Nut, Washers, Solder Lug Included
Condition: New Old Stock
Quantity: 1
DESCRIPTION
New old stock Motorola 1N3208 stud-mount rectifier diode in a DO-5 (DO-203AB) package, rated 15A and 50V. The ceramic body is marked with the Motorola logo, "1N3208," the diode polarity symbol, and date code 7244. It comes in its original bag with a typed ECG label reading "ECG-5940 1N-3208 R-50PRV 15A Cathode Case DO-5." The mounting hardware is installed on the stud: hex nut, washers, and solder lug terminal. Never installed. Light surface tarnish from age, as pictured.
Features:
Motorola 1N3208 standard recovery rectifier
50 V repetitive peak reverse voltage
15 A average forward current
250 A peak surge current
DO-5 (DO-203AB) threaded stud package
Standard polarity, with cathode to case/stud
Eyelet anode terminal on top
Mounting nut, washers, and solder lug included
Date code 7244
Original ECG-labeled bag
Compatibility:
Direct replacement for a 1N3208 from any manufacturer, including ECG5940 and NTE5940. It also replaces lower-voltage standard-polarity DO-5 15A stud rectifiers in the same footprint. Do not use it in place of a reverse-polarity "R" version (1N3208R / NTE5941), where the anode is the case.
Q&A
Q: Which terminal is the cathode?
A: The case and threaded stud are the cathode. The top eyelet terminal is the anode.
Q: Is this the same as an NTE5940?
A: Yes. ECG5940 / NTE5940 is the cross-reference for the 1N3208, and the original bag label lists both.
Q: Can I use it in place of a 1N3208R?
A: No. The R suffix means reverse polarity (anode to case). This is the standard cathode-to-case version.
Q: Does it need a heatsink?
A: For currents near its 15A rating, mount it to a heatsink or chassis with the included hardware.
