Application Circuit Review

Physical Dimensions and Package Information

The SN51DP is housed in a 5-pin TO-220-like package (often labeled as SIP-5 or TO-220-5). Unlike standard TO-220 packages, the mounting tab is electrically isolated, simplifying heat sink attachment.

Typical Dimensions (mm):

• Body Length: 20.0 – 22.0 mm
• Body Width: 10.0 – 11.0 mm
• Height (including pins): 15.0 – 16.0 mm
• Pin Pitch: 1.7 mm (center to center)
• Mounting Hole: 3.2 mm diameter

Thermal Data:

• Junction-to-Case Thermal Resistance (RθJC): 3.5 °C/W (typical)
• Operating Junction Temperature (Tj): -20°C to +125°C
• Storage Temperature (Ts): -40°C to +150°C

2. Input Stage (LED)

• Forward voltage ~1.2–1.4 V (typical).
• Trigger current (IFT): ~5–10 mA max (some datasheets specify 15 mA max).
• Compatible with 3.3V or 5V logic directly with a current-limiting resistor (e.g., 220–470 Ω for 5V).

Reliability & Long-Term Use

• No moving parts → high reliability.
• LED degradation over decades, but minimal under normal drive (≤20 mA).
• Temperature derating: above 80°C, output current must be reduced.
