Product details

PROFET high-side switch — 35 mOhm Rds(on) in a TO-220-5

The Infineon BTS436L2S is a single-channel PROFET® high-side power switch in a through-hole TO-220-5 package (PG-TO220-5-12). It switches a resistive or inductive load on the high side with a typical on-resistance of 35 mOhm, rated for a continuous output current up to 8.8 A. The load supply range spans 4.75 V to 41 V, and the switch does not require a separate Vcc supply — it is self-powered from the load voltage. The input is non-inverting with a simple On/Off interface, and the output is an N-channel MOSFET with a 1:1 input-to-output ratio.

Fault protection and temperature range

Built-in fault protection covers current limiting (fixed), open load detection, over-temperature shutdown, and over-voltage clamping. A status flag output signals fault conditions to the system controller.

Obsolete — sourcing through independent distribution

The BTS436L2S carries an Obsolete lifecycle status. Procurement for this part runs through independent distribution and surplus channels. No stock-holding claim is made here — each order is sourced per RFQ.

Frequently asked questions

Where can I buy BTS436L2S?

The BTS436L2S is obsolete and sourced through independent distribution. Submit an RFQ for current availability and pricing — each order is quoted against the requested quantity.

What is the Rds(on) of BTS436L2S?

The typical on-resistance is 35 mOhm. This is the conduction loss floor at 25°C junction temperature; actual Rds(on) increases with temperature per the normalised curve in the datasheet.

What is the difference between BTS436L2S and BTS436L2?

The base product number is BTS436L2. The 'S' suffix on BTS436L2S typically indicates a specific packaging or ordering variant — the electrical specifications (35 mOhm Rds(on), 8.8 A output, fault protection set) are shared across the family. Confirm the exact package code and temperature grade against your BOM position.
