Overview
The onsemi 1N456A is a small signal switching diode designed for high conductance and low leakage applications. It features a single configuration housed in the DO-35 through-hole package. Key electrical parameters include a peak reverse voltage of 30 V, a forward current rating of 500 mA, and a maximum surge current of 4 A. The device exhibits a forward voltage of 1 V and a reverse current of 25 nA. It operates within a temperature range of -65 °C to +175 °C.
Feature Summary
- High conductance characteristics for efficient signal handling
- Low leakage performance ensuring minimal reverse current flow
- Robust thermal stability suitable for wide operating temperatures
Applications
- General purpose rectification circuits
- Small signal switching applications
- Clamping and protection circuits
Procurement Notes
Verify the specific suffix (e.g., ATR) against official datasheets to confirm packaging type such as reel or cut tape. Ensure the component meets RoHS and REACH compliance requirements for your region. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm lead times and production cycles directly with the supplier before finalizing orders.
Selection Notes
Select this component when a 30 V reverse voltage rating is required alongside a 500 mA forward current capacity. The DO-35 package is appropriate for through-hole mounting processes. Consider the low leakage specification if circuit sensitivity to reverse bias currents is critical. Verify that the operating temperature range aligns with the environmental conditions of the target application.
Part Context
This diode belongs to the 1N456A series of small signal switching devices manufactured by onsemi. It is categorized under general purpose diodes and diodes & rectifiers subcategories. The product is actively listed in the manufacturer's portfolio, indicating ongoing availability and support for design-in projects requiring standard silicon switching capabilities.
Replacement Considerations
Direct substitutes may include other 1N456A variants from different manufacturers provided they match the DO-35 package and electrical ratings. Verify pinout compatibility and thermal characteristics before substitution. Generic equivalents must maintain the 30 V reverse voltage and 500 mA forward current specifications.
