Product Overview

The BAL74 is a high-speed silicon switching diode carried forward from the legacy Philips Semiconductors discrete catalog and still published by Nexperia. The piece photographed here is a black SOT-23 body on a dark textured backdrop with three bright metal leads, and the top face carries a short type code rather than the part name: it reads JC, with a smaller p and a 57 set to the right of it. 2900 of this part number are on the shelf, sold one at a time.

Key Features

• Type: high-speed silicon switching diode, single, surface mount
• Repetitive peak reverse voltage: 50 V (V_RRM, per Nexperia's published BAL74 data)
• Repetitive peak forward current: 500 mA (I_FRM, per Nexperia's published BAL74 data)
• Forward current: 250 mA, carried over from this listing's own existing copy
• Reverse recovery time: 4 ns maximum, per Nexperia's published BAL74 data
• Package: SOT-23, three leads, reflow or hand solder
• Marking on the photographed body: JC, with a smaller p and 57 alongside
• Series: legacy Philips discrete catalog, held by Nexperia since 2017
• Verify against Nexperia's published BAL74 data before designing in.

Applications

• Signal steering and clamping on small-signal lines
• Catch and freewheel positions on low-current LED or relay drivers
• Fast switching in RF and IF stages
• Surface mount board repair calling out a SOT-23 signal diode

Frequently Asked Questions

How many should I order?
Order the count the build needs. 2900 of this part number are on the shelf, sold one at a time, so a whole board's worth and a drawer of spares come out of a single order line. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.

What is printed on a body this small?
Not the part number. A SOT-23 has no room for it, so the maker prints a short type code instead. On the piece photographed here that code reads JC, with a smaller p and 57 to the right of it. We will tell you exactly what is on the body; we will not decode it for you, because the BAL74 data we work from covers electrical ratings and says nothing about marking codes.

Four nanoseconds of recovery time, on a body barely wide enough to hold two letters.
