Technical Details & Description

3750Vrms isolation in a 5-lead SOIC — what that buys you

The Toshiba TLP109(TPR,E) is a single-channel DC-input transistor-output optocoupler rated for 3750Vrms isolation in a 5-lead SOIC package.

Turn-on and turn-off times are both 800ns typical, 800ns max.

Output drive and forward current — staying within the SOA

Output transistor rated for 20V maximum and 8mA continuous per channel.

Package note — 5-lead 6-SOIC is non-standard land pattern

The package is a 6-SOIC body width 4.55mm, but with only 5 leads. If your PCB has a standard 6-pin SOIC footprint, pin 6 pad will be unconnected — that is fine electrically, but the mechanical outline may differ from a standard SOIC-6. Verify the land pattern against the Toshiba mechanical drawing before committing the board.

ROHS3 means no exemptions for lead in solder or PBB/PBDE flame retardants, which simplifies EU and UKCA compliance paperwork.

Frequently asked questions

What are the complete specifications of TLP109(TPR,E)?

Design engineers need exact specs like isolation voltage, CTR, and package to validate fit in their circuit.

Is TLP109(TPR,E) active or obsolete?

Brokers and buyers need lifecycle status to ensure long-term availability and avoid last-time buys.

Where can I buy TLP109(TPR,E) in small quantities?

Prototyping and low-volume production require distributors that stock single reels or cut tape.

What is the recommended replacement for TLP109(TPR,E) if it becomes unavailable?

Sourcing buyers and maintenance techs need drop-in alternatives to avoid redesign or downtime.

What is the pinout and internal schematic of TLP109(TPR,E)?

Design engineers and repair techs need pin configuration to correctly integrate or troubleshoot the optocoupler.

How does TLP109(TPR,E) compare to similar optocouplers like TLP185?

Engineers evaluating multiple options need parametric comparisons for CTR, speed, and isolation to select the best part.
