Detailed Description

Quad-channel photocoupler (optocoupler) with phototransistor outputs. Surface‑mount SOIC/SOP-16 form factor. CTR “GB” rank. “TP” indicates tape-and-reel packaging. New, original TOSHIBA product. Classified under Integrated Circuits (ICs) > Specialized ICs. Available stock quantity: 2400.

Key Features

Four independent optocoupler channels in one SO-16 package

Phototransistor outputs for easy interfacing to logic and analog circuits

High isolation between input and output for safety and noise immunity

Low LED drive current requirement

CTR “GB” grouping for controlled current transfer characteristics

Surface-mount, tape-and-reel for automated assembly

RoHS compliant and halogen-free options (refer to datasheet)

Wide operating temperature range (industrial grade; see datasheet)

Designed for general-purpose signal isolation

Key Advantages

Integrates four channels to save PCB area and BOM cost

Simple drive and readout (LED in, transistor out) reduces design effort

Strong isolation helps block ground loops and high common-mode noise

SMD packaging supports high-volume, automated production

Stable CTR group improves lot-to-lot consistency

Broad ecosystem and long-term supply from a tier-1 manufacturer

Packaging

Type: Tape-and-Reel (suffix TP), suitable for pick-and-place

Package/Case: SOIC/SOP-16 (manufacturer case code 1057)

Body material: Molded epoxy resin, UL94 V-0 qualified (typical for Toshiba optocouplers)

Pin configuration: 16 pins total; 4 LED inputs (anode/cathode pairs) and 4 phototransistor outputs (collector/emitter pairs), one channel per pair

Pitch and size: Standard SO-16 footprint with 1.27 mm pin pitch (typical for SOIC-16)

Thermal characteristics: Good thermal path via leads; observe derating guidance in the datasheet for ambient temperature and power dissipation per channel

Electrical properties overview: Phototransistor output, high isolation voltage, CTR ranked “GB,” low LED forward current drive; detailed limits and test conditions in the datasheet

Moisture sensitivity: Supplied in dry-packed tape-and-reel; follow MSL handling per datasheet/label

Reel count: Optimized for high-volume assembly; contact us if you need exact units per reel

Lifecycle

Current status: Active and in production as of our latest update

Not approaching discontinuation to our knowledge; we monitor notices from Toshiba

Potential equivalents/alternatives (verify all specs and footprints before use):

- Toshiba TLP290-4 series (quad phototransistor coupler, standard CTR)

- Toshiba TLP284-4 series (quad, low input current/high CTR variant)

- Toshiba TLP521-4 (quad, through-hole DIP if THT is acceptable)

- Other brands’ quad phototransistor optocouplers with SO-16 footprint can be considered as functional alternatives
