Product details
Overview
FZT753TC from Diodes Incorporated is a 100V PNP high-performance bipolar junction transistor in SOT223 package, rated for -2A continuous collector current and -6A peak pulse current, with VCE(sat) < -300mV at -1A, used in automotive power switching, industrial DC-DC converters, and high-reliability load control circuits.
For engineers reviewing the FZT753TC datasheet, FZT753TC pinout, FZT753TC application, or FZT753TC equivalent, key selection criteria include breakdown voltage (BVCEO = -100V), thermal resistance (RθJA = 41.7°C/W on 50mm × 50mm 2oz copper), AEC-Q101 qualification, and complementary pairing with FZT653.
Technical Context
This PNP transistor operates in linear and saturated switching modes with guaranteed BVCEO ≥ -100V and VBE(sat) ≤ -1.25V at -1A. Its fT of 100–140MHz supports medium-frequency switching up to ~100kHz in hard-switched topologies.
Thermal design relies on its RθJL of 12.9°C/W (junction-to-lead) and derated power dissipation: 3.0W on large copper, dropping to 1.2W on minimum pad layout. ESD robustness includes 4kV HBM rating per JEDEC Class 3A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -100V - Ensures safe operation in 48V and 60V industrial bus systems with margin against transients. |
| IC (cont.) | -2A - Supports sustained load switching in automotive body control modules and motor drivers. |
| VCE(sat) | < -300mV @ -1A - Minimizes conduction loss and self-heating in high-duty-cycle applications. |
| hFE | 25–200 - Enables direct base drive without amplification in low-speed logic-level interfaces. |
| fT | 100–140MHz - Permits use in PWM frequencies up to 100kHz with stable gain and phase response. |
| RθJA | 41.7°C/W (50mm×50mm 2oz Cu) - Defines heatsinking requirement for 3W operation at TA ≤ +85°C. |
Pinout & Package
SOT223 package with three terminals: emitter (E), base (B), and collector (C); molded green plastic case, UL 94V-0 rated, 0.112g weight, lead-free matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main current sink terminal | Connected to high-side supply rail; thermally coupled to PCB copper via exposed tab for heat dissipation. |
| Base (B) | Control input | Receives negative current to turn on; requires ≥ -100mA drive for full saturation at -1A IC. |
| Emitter (E) | Current source reference | Typically tied to system ground or load return; defines common reference for VBE and VCE measurements. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments (-40°C to +125°C ambient, 150°C junction). |
| Low VCE(sat) | < -300mV at -1A enables >95% efficiency in 12V/24V switched loads with minimal heatsink. |
| High BVCEO | -100V rating allows direct use in 48V battery systems without external clamping components. |
| Complementary NPN pair | FZT653 shares identical SOT223 footprint and thermal profile for push-pull or H-bridge designs. |
Applications
| Automotive Body Control Module | Industrial DC-DC Converter |
|---|---|

IC Role / Device Role / Timing Role: Low-loss series pass element in diode-replacement architecture. Use Value: RθJL = 12.9°C/W enables direct solder-mount thermal path to PCB plane, supporting continuous 1.5A operation without heatsink. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN25050DFH | Higher VCEO (-120V), lower IC (-1.5A), SOT89 package, no AEC-Q101 qualification | Preferred where higher voltage margin is critical but automotive compliance is not required | Select when operating above 80V or space-constrained layouts favor SOT89 |
| MJD2955T4G | Same VCEO (-100V), higher IC (-10A), TO-220 package, AEC-Q101 qualified | Used in higher-power motor drives where thermal mass and heatsink mounting are available | Choose for >3A continuous loads or forced-air-cooled industrial systems |
Compared with ZXTN25050DFH and MJD2955T4G, FZT753TC uniquely balances AEC-Q101 compliance, SOT223 surface-mount scalability, and 2A/100V capability-making it optimal for space-limited automotive and industrial modules requiring production traceability and thermal efficiency without TO-220 assembly overhead.

FAQ
What is the maximum allowable junction temperature for FZT753TC?
The absolute maximum junction temperature (TJ) is +150°C, with storage temperature matching this range. Operation at TJ > +150°C risks permanent degradation of hFE and increased leakage. Derating curves in DS33163 Rev.6 specify power limits versus ambient temperature based on PCB copper area.
Is FZT753TC pin-compatible with other SOT223 PNP transistors?
FZT753TC uses standard SOT223 pinout (C-B-E, left-to-right with tab facing down), matching industry convention. However, electrical parameters-including VCE(sat), hFE, and fT-differ significantly from generic SOT223 PNP parts; substitution requires validation of gain, saturation, and thermal performance in the target circuit.
Does FZT753TC require a base resistor in switching applications?
Yes. To ensure reliable saturation at -1A IC, a base current of ≥ -100mA is required. With typical VBE(sat) ≈ -0.9V, a 10Ω resistor driven from a -5V logic source delivers -410mA base current, guaranteeing deep saturation and minimizing switching losses.
How does the "Green" designation affect FZT753TC's material composition?
The "Green" designation confirms halogen- and antimony-free status: total Br+Cl < 1500ppm (each < 900ppm), antimony < 1000ppm. This meets IPC-1752 and EU ELV requirements, enabling use in environmentally regulated markets without material declaration exceptions.
