The Toshiba TLP3052AF is a triac-output photocoupler (photorelay) that pairs an infrared GaAs LED with a non-zero-crossing photo-triac detector. It is designed to drive larger AC loads and triacs, providing optical isolation between a low-voltage control circuit and an AC mains-referenced output. The “AF” variant is supplied in the lead-formed DIP6 (F type) body for surface mounting.
The TLP3052AF is a specialized Toshiba isolation component with limited authorized-distributor availability, which makes it a frequent target for shortages and obsolescence-driven sourcing. Pacific Component Xchange is an independent distributor focused on hard-to-find and end-of-life power-management ICs and optocouplers. We help engineers and buyers secure stock of allocated, scarce, and obsolete parts like the TLP3052AF when traditional channels come up empty.
Every order is backed by our authenticity and quality program, with traceability and inspection to protect your build against counterfeit risk. We ship globally and can match exact packaging and tape-and-reel codes where required. Request a quote (RFQ) for the TLP3052AF today and our sourcing team will respond with current availability, lead time, and pricing.
The clean base orderable part number is TLP3052AF, a Toshiba non-zero-cross triac-output photocoupler (photorelay). Trailing characters seen in some listings (such as TP-suffix codes) are Toshiba packing/tape-and-reel designators rather than part of the device part number.
It is a non-zero-crossing (NZC) photo-triac output, meaning the output can be triggered at any point in the AC cycle. This makes it suitable for phase-control and inductive-load applications.
The TLP3052AF provides 5000 Vrms (minimum) isolation voltage, tested at AC for 60 seconds, and supports UL 1577, cUL, EN 60747-5-5 (VDE), and CQC (GB 4943.1) safety standards.
It uses Toshiba's 5-pin DIP6 (F type) package, a lead-formed surface-mount body measuring approximately 7.12 x 10.16 x 3.65 mm.
Key absolute maximum ratings include 600 V peak off-state voltage (VDRM), 100 mA R.M.S. on-state current (Ta = 25 C), 2 A pulsed on-state current, 1.2 A peak non-repetitive surge current, an operating temperature range of -40 to 100 C, and a storage temperature range of -55 to 150 C.
Toshiba lists the TLP3052AF as under full production, though authorized-distributor stock is often limited and Toshiba notes alternative parts for some new designs. Pacific Component Xchange sources this hard-to-find photorelay on an RFQ basis; submit a quote request for current availability, lead time, and pricing.
