The 1N3345B is a high-power Zener diode from Motorola Semiconductor, designed for voltage regulation applications. It is part of a series registered under JEDEC standards, offering a wide Zener voltage selection from 3.9V to 200V.
This diode can be operated up to 50W with adequate mounting and heat sinking due to its low thermal resistance. It features internal solder bond construction and is hermetically sealed. Standard voltage tolerances are ±5% (B suffix), ±10% (A suffix), and ±20% (no suffix), with options for ±2% or ±1% available upon factory consultation.
The 1N3345B is housed in an industry-standard DO-5 (DO-203AB) package, suitable for through-hole mounting. It has a maximum DC power dissipation of 50 watts at a case temperature below 75°C, with power derating at 0.5 W/°C above 75°C. The operating and storage temperature range is -65°C to +175°C.
