The component and packaging may display cosmetic wear, marks, or discoloration from long-term storage and handling. No functional testing has been performed. Please review all photographs for the exact condition, markings, and included item.

COMPATIBILITY & CROSS-REFERENCE
Listed cross-references: ECG5994, GE-5104, and SK3501 (600V, 40A, DO-5, cathode to case). Direct replacement for an NTE Electronics NTE5994.
Polarity is specific: this part is cathode to case. Anode-to-case versions such as the NTE5995 are not a drop-in match, so verify polarity, mounting, and heat-sinking before installing.

Q&A
Q: What is an NTE5994?
A: A 600V, 40A silicon power rectifier in a DO-5 stud-mount case with cathode-to-case polarity.
Q: What replaces an NTE5994?
A: Listed cross-references are ECG5994, GE-5104, and SK3501. Confirm suitability for your application.
Q: Can I use an NTE5995 instead?
A: Not as a drop-in. The NTE5995 has the same 600V 40A rating but is anode to case, so polarity is reversed.
Q: What is the stud thread?
A: 1/4-28 UNF.
