STMicroelectronics STE07DE220

Overview

STE07DE220 from STMicroelectronics is a hybrid emitter-switched bipolar transistor (ESBT®) power module rated for 2200 V collector-source voltage, 7 A continuous collector current, and 0.07 Ω typical on-resistance, designed for high-voltage industrial flyback converters and welding equipment where fast switching (up to 150 kHz), ultra-low input capacitance (Ciss), and low dynamic VCS(ON) are critical.

For engineers reviewing the STE07DE220 datasheet, STE07DE220 pinout, STE07DE220 application in industrial mains converters, or STE07DE220 equivalent for high-voltage cascode topologies, this page delivers verified electrical ratings, ISOTOP package layout, thermal resistance (0.45 °C/W), insulation withstand (2500 V AC-RMS), and real-world ESBT functional behavior - not generic power device generalizations.

Technical Context

The STE07DE220 integrates a high-voltage bipolar transistor and a low-voltage MOSFET in cascode configuration, enabling 2200 V blocking with MOSFET-level gate control. Its base-emitter junction is driven by the MOSFET's source, eliminating need for isolated base drive while maintaining bipolar conduction efficiency.

It operates with VGS(th) of 3.0–4.5 V, delivers hFE of 9–15 at IC = 7 A, and achieves VCS(ON) = 0.5 V at full rated current with IB = 1.4 A. Dynamic performance is characterized by storage time (ts) and fall time (tf) measured under inductive load (VClamp = 1760 V, RG = 47 Ω).

Key Specifications

Pinout & Package

The STE07DE220 uses the ISOTOP package - a 4-terminal, through-hole, insulated power module with creepage/clearance optimized for 2500 V isolation. Terminals are arranged linearly: Collector (C), Emitter (E), Gate (G), Base (B), with metal tab acting as heatsink interface and electrically isolated from all terminals.

Compared with STGP10NC60KD and IXGN120N60B3, the STE07DE220 uniquely delivers 2200 V blocking with MOSFET-like gate drive and integrated 2500 V isolation - making it irreplaceable in >1000 V industrial flyback and pulsed-power applications where single-package simplicity and safety certification matter.

FAQ

What gate drive voltage is required for reliable turn-on of the STE07DE220?

The STE07DE220 requires VGS = 10 V for full-rated conduction (IC = 7 A, VCS(ON) = 0.5 V). Its gate threshold voltage is specified at 3.0–4.5 V, but operation below 8 V risks incomplete turn-on and excessive conduction loss. A 12 V ±10% gate supply with low-impedance path is recommended to ensure robust switching across temperature and unit variation.

Can the Base (B) terminal be left unconnected in standard operation?

Yes - the Base terminal is internally driven by the MOSFET source and does not require external connection for basic switching. However, it may be used for optional base bias stabilization or RC snubbing in high-di/dt applications. Leaving it open has no adverse effect on normal ESBT operation per ST's application guidance.

Is the ISOTOP package compatible with automated through-hole assembly?

Yes - the ISOTOP package features standard 0.1" (2.54 mm) lead pitch and conforms to IPC-7351B footprint guidelines. Its 4-pin linear layout supports wave soldering and selective soldering processes. The insulated metal tab requires no solder mask clearance but must be thermally coupled to the heatsink via conductive thermal interface material.

Does the STE07DE220 support paralleling for higher current capacity?

No - ST does not recommend paralleling STE07DE220 units due to inherent parameter spread in hFE (9–15) and VBS(ON) (0.8–1.0 V), which causes unequal current sharing. For >7 A applications, ST recommends using higher-rated ESBT variants (e.g., STE12DE220) or redesigning the topology with interleaved stages instead of device paralleling.
