Product details
Overview
STC08DE150HV from STMicroelectronics is a hybrid emitter-switched bipolar transistor (ESBT®) rated for 1500 V collector-source voltage, 8 A continuous collector current, and 0.075 Ω equivalent ON resistance. It integrates high-voltage bipolar and low-voltage MOSFET technologies in a TO-247-4L HV package and is engineered for auxiliary flyback SMPS in three-phase industrial power supplies.
For engineers reviewing the STC08DE150HV datasheet, STC08DE150HV pinout, STC08DE150HV application, or STC08DE150HV equivalent, key selection criteria include its squared RBSOA up to 1500 V, fast switching capability up to 150 kHz with RG = 47 Ω, low Ciss of 750 pF, and gate-driven base control enabling simplified drive circuitry in high-voltage offline converters.
Technical Context
The STC08DE150HV implements an ESBT topology where a low-voltage MOSFET controls the base of a high-voltage bipolar transistor, decoupling gate drive requirements from collector voltage stress. Its internal structure enables simultaneous high breakdown voltage (1500 V VCS(SS)) and low conduction loss (VCS(ON) = 0.6 V at IC = 8 A, IB = 1.6 A).
It features a pulsed DC current gain (hFE) of 4.5–10 under defined test conditions, storage time (ts) as low as 526 ns, and dynamic collector-source voltage overshoot limited to 6 V (0.5 µs) and 2.2 V (1 µs) during turn-off - all validated with RG = 47 Ω and clamped inductive load testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCS(SS) | 1500 V - supports direct connection to 1000 V DC bus or rectified three-phase mains without snubber |
| IC | 8 A continuous - delivers stable output power in auxiliary SMPS up to ~100 W at high efficiency |
| RCS(ON) | 0.075 Ω - reduces conduction losses and thermal stress vs. conventional IGBTs in same voltage class |
| Ciss | 750 pF at VCS = 25 V - enables fast switching up to 150 kHz with moderate gate drive strength (RG = 47 Ω) |
| ts / tf | 526 ns / 8.5 ns - short storage time minimizes switching energy loss during turn-off in hard-switched flyback |
| TJ(max) | 125 °C - defines maximum junction temperature for reliable operation under sustained 156 W dissipation limit |
| RthJC | 0.64 °C/W - allows thermal design with standard heatsinking for TO-247-4L HV mounting |
Pinout & Package
STC08DE150HV is housed in a TO-247-4L HV package with four isolated terminals: Collector (C), Emitter (E), Gate (G), and Base (B). The fourth pin enables direct base access for optimized drive and improved safe operating area control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Collector (C) | High-voltage main current path terminal; electrically connected to metal tab for thermal and electrical grounding |
| Pin 2 | Emitter (E) | Common emitter node for both bipolar and MOSFET sections; referenced ground for gate drive return |
| Pin 3 | Gate (G) | Low-voltage MOSFET gate input; controls base current injection with ±20 V rating and 500 nA leakage |
| Pin 4 | Base (B) | Direct access to bipolar transistor base; enables external base current limiting or active clamping |
Key Features
| Feature | Design Value |
|---|---|
| Squared RBSOA | Rated up to 1500 V with full 8 A current capability - eliminates derating across voltage range in inductive switching |
| Hybrid ESBT structure | Combines MOSFET gate control with bipolar conduction - achieves lower RCS(ON) than comparable IGBTs |
| Low Ciss & fast switching | 750 pF input capacitance enables 150 kHz operation with minimal gate drive power and reduced EMI |
| Direct base terminal | Pin 4 provides external base access - supports active base control, snubberless turn-off, and precise timing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage flyback switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGW30H65DFB | 650 V IGBT with FRD; higher VCE(sat) (1.8 V), no base terminal, slower tf (100 ns) | Limited to ≤650 V DC bus; requires snubber in 1000 V systems; no base control for dynamic SOA tuning | Choose only if system voltage ≤650 V and cost sensitivity outweighs SOA flexibility |
| IXTH30N50L | 500 V N-channel MOSFET; RDS(on) = 0.12 Ω; no bipolar gain; lacks 1500 V rating | Not suitable for direct three-phase rectified bus use; requires stacked or cascode configuration for >600 V | Select only for lower-voltage, high-frequency resonant topologies where gate charge (Qg = 65 nC) is critical |
Compared with STGW30H65DFB and IXTH30N50L, STC08DE150HV uniquely supports 1500 V operation with base-accessible ESBT architecture - enabling snubberless, high-SOA flyback designs unattainable with standard IGBTs or MOSFETs alone.

FAQ
What is the recommended gate resistor value for STC08DE150HV?
The datasheet specifies performance validation with RG = 47 Ω, achieving ts = 526 ns and tf = 8.5 ns under defined inductive load conditions. Lower values (e.g., 22 Ω) reduce switching time but increase gate current stress; higher values (e.g., 100 Ω) improve EMI but extend ts and raise switching loss. Thermal and SOA limits must be verified per application.
Does STC08DE150HV require a negative gate voltage for turn-off?
No. STC08DE150HV uses a unipolar gate drive: VGS = 0 V turns off the MOSFET section, removing base drive and allowing the bipolar transistor to commutate naturally. The device is rated for VGS = ±20 V, but negative voltage is not required or specified for reliable turn-off in standard flyback operation.
Can STC08DE150HV be used in hard-switched forward converters?
No - the device is optimized for flyback topologies with clamped inductive loads. Its RBSOA and dynamic voltage ratings (e.g., VCSW = 1500 V) assume snubberless operation in flyback circuits. Forward converters impose different voltage/current stress profiles and lack the natural voltage clamping inherent to flyback, risking SOA violation.
Is STC08DE150HV still in active production?
Per STMicroelectronics' official documentation (Doc ID 12799 Rev 2), STC08DE150HV is marked "Obsolete Product(s)" in the datasheet header and revision history. However, Aetrix Electronics maintains legacy inventory and offers lifecycle management support including last-time buy planning and cross-reference assistance for qualified replacements.
