Product details
Overview
FZT560TC from Diodes Incorporated is a 500V PNP high-voltage transistor in SOT223 package, rated for -150mA continuous collector current and -500V collector-emitter breakdown voltage, with VCE(sat) ≤ -500mV at IC = -50mA/IB = -10mA, used in flyback snubber circuits and high-side switching in industrial power supplies.
For engineers reviewing the FZT560TC datasheet, FZT560TC pinout, FZT560TC application, or FZT560TC equivalent, key selection criteria include verified -500V BVCEO, thermal resistance of 41.7°C/W on 50mm × 50mm copper, ESD HBM rating of 4000V, and SOT223 (Type DN) lead-frame configuration with collector-connected tab.
Technical Context
This PNP bipolar junction transistor operates in linear and switching modes with guaranteed -500V blocking capability under IC = -1mA, supports pulsed operation up to -500mA peak current, and delivers hFE = 80–300 at IC = -50mA/VCE = -10V.
Its safe operating area is defined up to 100ms pulse width at -500V/-50mA, with transient thermal impedance of 14.8°C/W junction-to-leads, and fT = 60MHz at VCE = -20V/IC = -10mA for moderate-frequency switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VCEO | -500 V - guarantees reliable high-voltage isolation in offline SMPS primary-side snubbers |
| Continuous Collector Current | -150 mA - supports sustained conduction in auxiliary bias windings and gate-drive clamps |
| VCE(sat) @ IC=-50mA | ≤ -500 mV - minimizes conduction loss in active-clamp and crowbar protection circuits |
| DC Current Gain hFE | 80–300 @ IC=-50mA - enables stable base drive design across production spread |
| Thermal Resistance RθJL | 14.8 °C/W - allows direct heat transfer from die to PCB copper via collector tab |
| ESD HBM Rating | 4000 V - ensures robustness during board assembly and handling in industrial environments |
| fT | 60 MHz - supports switching up to ~5–10 MHz in resonant gate-drive or signal-level amplification |
Pinout & Package
Package: SOT223 (Type DN), surface-mount, thermally enhanced with exposed collector tab soldered directly to PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (Tab) | Main current sink and thermal path | Electrically and thermally connected to large copper area; must be soldered for rated power dissipation |
| Emitter | Current source terminal | Connected to high-side rail or reference node; carries full load current in switching mode |
| Base | Control input | Receives negative drive current to turn on; requires external current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| High-Voltage Blocking | Guaranteed -500V VCEO enables use in 400V DC bus and 230VAC rectified systems without derating |
| Thermally Optimized Package | SOT223 (Type DN) with low 14.8°C/W RθJL permits 3W dissipation on 50mm × 50mm 2oz copper |
| Robust ESD Protection | 4000V HBM rating reduces risk of field failure during handling and reflow |
| Green Compliance | Halogen- and antimony-free, RoHS 3 compliant (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Industrial Flyback Snubber | High-Side Gate Clamp |
|---|---|
Use Scenario: Absorbs leakage inductance energy in offline flyback converters operating at 400V DC input. IC Role / Device Role / Timing Role: PNP transistor configured as active clamp, turning on during MOSFET off-time to recycle energy. Use Value: Reduces voltage stress on primary switch by limiting VDS overshoot to <550V while maintaining <1% efficiency penalty. | Use Scenario: Clamps gate voltage of high-side N-channel MOSFETs in half-bridge motor drivers. IC Role / Device Role / Timing Role: Fast-turn-off PNP shunt that sinks gate charge when driver output falls below threshold. Use Value: Prevents shoot-through by ensuring gate voltage drops below 1.5V within 1.5µs, validated at 100kHz switching. |
| AC-DC Auxiliary Bias Supply | Overvoltage Crowbar Circuit |
Use Scenario: Regulates isolated +12V bias rail derived from transformer auxiliary winding in telecom PSUs. IC Role / Device Role / Timing Role: Linear pass element controlled by TL431 feedback loop to maintain tight output regulation. Use Value: Delivers stable 12V/100mA with ±2% line/load regulation across -40°C to +125°C ambient. | Use Scenario: Triggers SCR-based shutdown when main DC bus exceeds 450V in UPS and battery backup systems. IC Role / Device Role / Timing Role: High-voltage sensing switch that conducts only above precise threshold set by Zener divider. Use Value: Activates crowbar within 100ns of overvoltage detection, limiting bus excursion to <475V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZTX653 | Lower VCEO (-300V), higher hFE (100–600), same SOT223 package | Not suitable for 400V+ bus applications; limited to 265VAC-derived supplies | Select only where voltage stress remains <280V and higher gain improves base drive margin |
| MJD2955T4G | Higher IC (-10A), TO-220 package, VCEO = -70V | Requires heatsink; incompatible with SOT223 footprint; suited for high-current linear regulators | Choose only when >500mA continuous current is required and board space allows TO-220 mounting |
Compared with ZTX653 and MJD2955T4G, FZT560TC uniquely balances -500V blocking, SOT223 thermal performance, and industrial-grade ESD robustness-making it optimal for compact, high-reliability 400V-class power management where voltage rating and package size are jointly constrained.

FAQ
What is the maximum allowable PCB copper area for thermal performance validation?
The datasheet specifies two validated configurations: 25mm × 25mm 2oz copper yields RθJA = 62.5°C/W, while 50mm × 50mm 2oz copper achieves RθJA = 41.7°C/W. For 3W operation, the larger pad is mandatory to keep junction temperature below 150°C at 25°C ambient. No derating is specified beyond these two layouts.
Can FZT560TC replace FZT560TA in existing designs?
Yes-FZT560TC and FZT560TA share identical electrical specifications, SOT223 (Type DN) package, and marking code "FZT560". The only difference is tape-and-reel packaging: TC uses 13-inch reels with 4,000 units; TA uses 7-inch reels with 1,000 units. Footprint, solder profile, and thermal behavior are fully interchangeable.
Is the collector tab electrically isolated from other pins?
No-the collector is internally bonded to the exposed metal tab, which serves as both the primary current path and thermal conduction interface. The tab must be soldered to a dedicated PCB copper pour and cannot be left floating or insulated without violating absolute maximum ratings and thermal specifications.
Does FZT560TC meet AEC-Q101 for automotive use?
No-FZT560TC is not qualified to AEC-Q101. Diodes offers the automotive-grade variant FZT560Q, which undergoes additional stress testing including HTOL, temperature cycling, and bias HAST per AEC-Q101 Rev D. FZT560TC is intended for industrial, commercial, and telecom applications only.
