# CA3046 (Component) ## Description RF Transistor 5 NPN 15V 50mA 550MHz 300mW Through Hole 14-PDIP The CA3046 contains five matched NPN bipolar junction transistors (BJTs) integrated on a single silicon chip. These transistors share a common substrate but are electrically isolated from each other, allowing flexible circuit configurations. It is commonly used in analog circuits where closely matched transistor characteristics are required, such as differential amplifiers and current mirrors. Key Features Type: NPN transistor array IC Number of Transistors: 5 matched transistors Integrated Structure: Monolithic silicon chip Isolation: Each transistor is individually accessible Matching: Good thermal and electrical matching between transistors Package: Typically 14-pin DIP or SOIC (varies by manufacturer) Electrical Characteristics (typical) Collector-emitter voltage (Vce): up to ~15 V (varies by variant) Collector current: a few milliamps per transistor (low-power signal applications) Frequency response: suitable for low to medium-frequency analog circuits Operating temperature: industrial range (depends on manufacturer spec) Typical Applications Differential amplifiers Current mirrors Temperature sensing circuits Signal processing circuits Oscillators and timing circuits General-purpose analog transistor building blocks #CommonPartsLibrary #Transistor # BJT #RF-transistor #Bipolar ## Component Details - **Owner:** adrian95 - **Created:** 4/24/2026 - **Last Updated:** 4/24/2026 - **Visibility:** Public - **Part Type:** Transistor - **Datasheet URL:** https://rocelec.widen.net/view/pdf/hqlk54qn0l/RE_DSHEET_CA3046_REI.pdf?t.download=true&u=5oefqw - **Manufacturer Part Number:** CA3046 - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Name:** Rochester Electronics, LLC - **Part Type:** Transistors - **Sub-Type:** NPN - **MPN:** CA3046 - **Mount Type:** Through Hole - **Package / Case Code:** 14-SOIC - **Pin Count:** 14 ## Pins | Pin | Name | Type | |-----|------|------| | 1 | Q1C | | | 2 | Q1B | | | 3 | E | | | 4 | Q2B | | | 5 | Q2C | | | 6 | Q3B | | | 7 | Q3E | | | 8 | Q3C | | | 9 | Q4B | | | 10 | Q4E | | | 11 | Q4C | | | 12 | Q5B | | | 13 | Q5E | | | 14 | Q5C | | --- *Generated from [https://www.flux.ai/adrian95/ca3046](https://www.flux.ai/adrian95/ca3046)*
