Product Overview
Silicon Zener voltage regulator diode rated for 20 volts nominal and 1.5 watts in a flanged Case 55 metal enclosure. Built with two gold-plated through-hole leads and the cathode tied internally to the case, Motorola 1N3796B provides stable voltage regulation with plus-or-minus 5 percent tolerance.
Key Features
- Nominal Zener voltage: 20 V with ±5% tolerance
- Power dissipation: 1.5 W
- Test current (Izt): 19 mA
- Maximum dynamic impedance: 16 Ω
- Operating junction temperature range: -65°C to +175°C
- Case 55 flanged metal can with gold-plated leads
Applications
- Bench power supply repair and legacy analog voltage reference rails.
- Vintage test equipment calibration boards and industrial control circuitry.
- Custom hobbyist linear regulator builds requiring stable 20V clamping.
Frequently Asked Questions
What is the pinout and case connection for this diode?
The cathode connects internally to the metal can case, with two gold-plated wire leads extending from the bottom header for through-hole circuit connection.
What part numbers cross-reference to the 1N3796B?
The 1N3796B interchanges directly with Motorola internal number 1.5M20Z5 and military logistics specification NSN 5961-00-901-3231.
Solid Motorola metal-can regulation from the golden age of discrete silicon. Drop it into your circuit and let the 20-volt rail hold true.
