Sn51dp Datasheet Verified |top| Jun 2026

Avoid generic PDF-sharing sites unless you cross-check the document number (e.g., IR-SN51DP-DS-v2.3) and the revision date.

: The OB3350CP is packaged in an SOP-8, which has a different pin count and physical footprint. While pin functions may be similar, a direct replacement is not possible without a dedicated adapter board.

Some variants of the SN51DP include an internal snubber network (typically 39Ω + 0.01µF) between pins 3 and 4. This is confirmed in the official datasheet. sn51dp datasheet verified

Reliable PWM control for DC motor speeds and industrial lighting systems.

| Pin Number | Name | Function | |------------|------|-----------| | 1 | AC Input (+) | Anode of input LED (control side) | | 2 | AC Input (-) | Cathode of input LED | | 3 | Output Terminal 1 (L1) | Connected to main triac (load side) | | 4 | Output Terminal 2 (L2) | Connected to main triac (load side) |

For critical applications, always request a certificate of compliance from your distributor and perform statistical sampling per JEDEC standards. When in doubt, run the verification tests described in Part 6.
