NXP Semiconductors BT136X-600F,127

Overview

BT136X-600F from NXP Semiconductors is a planar passivated 4-quadrant triac in TO-220F (SOT186A) package, rated for 600 V repetitive peak off-state voltage, 4 A RMS on-state current, and 25 A non-repetitive peak on-state current. It serves as a bidirectional AC switching device in phase-controlled motor drives and solid-state relays, with isolated heatsink mounting and four-quadrant triggering capability.

For engineers reviewing the BT136X-600F datasheet, BT136X-600F pinout, BT136X-600F application, or BT136X-600F equivalent, key selection considerations include gate trigger current (30–70 mA), isolation voltage (2500 V_RMS), thermal resistance to heatsink (5.5 K/W), and dV/dt immunity (50–250 V/µs) under specified operating conditions.

Technical Context

This triac operates across all four quadrants (T2+/G+, T2+/G−, T2−/G−, T2−/G+) without requiring external polarity reversal, enabling simplified gate drive circuitry in universal AC control. Its planar passivation ensures voltage ruggedness up to 600 V_DRM, while the isolated TO-220F package provides 2500 V_RMS insulation between terminals and heatsink.

Thermal design relies on junction-to-heatsink resistance of 5.5 K/W (with thermal compound), supporting continuous 4 A RMS conduction at heatsink temperatures ≤92 °C. Dynamic performance includes turn-on time ≤2 µs and dV/dt immunity ≥50 V/µs in all quadrants, critical for reliable commutation in inductive loads.

FAQ

What is the maximum junction temperature specification for BT136X-600F?

The BT136X-600F has a maximum junction temperature (T_j) of 125 °C, as defined in the Absolute Maximum Ratings table. This limit must not be exceeded during operation, and thermal design must ensure that junction temperature remains within this bound under worst-case ambient and load conditions. The BT136X-600F datasheet specifies heatsink temperature limits (≤92 °C) and thermal resistance values to guide proper heatsink sizing and compound application for the BT136X-600F.

Does BT136X-600F support triggering in all four quadrants, and what does that mean for circuit design?

Yes, the BT136X-600F supports triggering in all four quadrants (T2+/G+, T2+/G−, T2−/G−, T2−/G+), meaning it can be turned on using either polarity of voltage between main terminals and gate. This eliminates the need for external polarity-reversal circuitry such as diode bridges or dual-gate drivers, simplifying gate drive design and reducing component count in universal AC control circuits using the BT136X-600F.

What is the isolation voltage rating of BT136X-600F, and how is it measured?

The BT136X-600F provides 2500 V_RMS isolation voltage (V_ISOL(RMS)) from all terminals to the external heatsink, tested with sinusoidal waveform at 50–60 Hz, clean/dust-free conditions, and 25 °C heatsink temperature. This rating confirms safe operation when the isolated mounting base is directly attached to a grounded metal chassis, a key advantage of the TO-220F package used in the BT136X-600F.

Can BT136X-600F replace BT136-600E in an existing design?

No-BT136X-600F is not a drop-in replacement for BT136-600E. While both share the same voltage and current ratings, BT136X-600F uses an isolated TO-220F (SOT186A) package, whereas BT136-600E uses a non-isolated TO-220AB package. Substituting BT136X-600F requires verification of heatsink isolation requirements and mechanical fit; the BT136X-600F mounting base is electrically isolated, unlike the conductive tab of BT136-600E.

What is the typical on-state voltage drop of BT136X-600F at rated current?

The BT136X-600F exhibits a typical on-state voltage (V_T) of 1.4 V at 5 A and 25 °C junction temperature, with a maximum of 1.7 V under the same conditions. This low forward voltage minimizes conduction losses and self-heating during continuous operation, contributing to efficient thermal performance in the BT136X-600F when used at its 4 A RMS rating.
