Product details
Overview
FZT1047ATC from Diodes Incorporated is a 10V NPN medium-power transistor in SOT223 package, rated for 5A continuous collector current and 20A peak pulse current, with low VCE(sat) of 25mV @ 500mA/10mA and hFE = 300–450 @ 1A. It serves as a high-current switching element in DC-DC converter output stages and motor drive half-bridges.
For engineers reviewing the FZT1047ATC datasheet, FZT1047ATC pinout, FZT1047ATC application, or FZT1047ATC equivalent, key selection criteria include its 10V VCEO rating, 44mΩ RSAT at 5A, thermal resistance of 41.7°C/W (on 52mm × 52mm 2oz Cu), AEC-Q101 qualification readiness, and SOT223 thermal pad compatibility with PCB copper area design.
Technical Context
This NPN bipolar junction transistor operates in linear or saturated switching mode with guaranteed gain hold-up up to 20A (hFE ≥ 60), enabling robust current amplification in high-duty-cycle power control. Its 35V VCBO and 7V VEBO support safe biasing margins in 12V rail systems.
Designed for thermally demanding applications, it delivers 3W power dissipation on optimized PCB layouts and features 4,000V HBM ESD rating-critical for assembly-line handling and automotive subsystem integration where transient immunity is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 10 V - Maximum allowable collector-emitter voltage under operating conditions; defines safe DC bus voltage ceiling in low-voltage switching circuits. |
| IC (continuous) | 5 A - Sustained collector current capability; supports 5A load switching without forced cooling in compact SOT223 footprint. |
| VCE(sat) @ 5A | 220–350 mV - Low saturation voltage ensures <1.75W conduction loss at full current, minimizing thermal stress in power stage designs. |
| hFE @ 5A | 200–330 - Confirmed DC current gain at full rated current; enables stable base drive sizing for predictable turn-on behavior. |
| RθJA | 41.7 °C/W - Junction-to-ambient thermal resistance on 52mm × 52mm 2oz Cu; determines required PCB copper area for thermal management. |
| fT | 150 MHz - Current gain-bandwidth product; supports fast switching in PWM frequencies up to ~1–2 MHz with adequate gain margin. |
| ESD HBM | 4,000 V - Human Body Model rating; qualifies device for handling in standard electronics manufacturing environments without special ESD controls. |
Pinout & Package
Package: SOT223 (Type DN), surface-mount, 4-pin configuration with integrated thermal pad (collector tab). Molded plastic body, matte tin-plated leads, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Reference node for base drive and current return path; electrically isolated from thermal pad. |
| 2 (Base) | Control input | Low-impedance gate-equivalent node requiring ~25mA drive for full 5A saturation; sensitive to layout inductance. |
| 3 (Collector) | Main current path | Connected internally to exposed thermal pad; must be soldered to large copper pour for thermal and electrical performance. |
| 4 (Collector Tab) | Thermal & electrical connection | Integral part of collector node; provides primary heat conduction path to PCB; not electrically isolated. |
Key Features
| Feature | Design Value |
|---|---|
| Low RSAT | 44 mΩ @ 5A - Enables <1.1W conduction loss at full current, reducing heatsink requirements in space-constrained modules. |
| High ICM | 20 A peak pulse - Supports short-duration surge currents in motor startup or capacitor charging without second breakdown. |
| Gain stability at high IC | hFE ≥ 60 @ 20A - Ensures reliable base drive margin even during overcurrent transients, improving fault tolerance. |
| AEC-Q101 readiness | PPAP-capable, IATF 16949 manufacturing - Meets foundational automotive qualification prerequisites for body electronics and power distribution modules. |
| Green compound | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - Complies with EU ELV Directive and major OEM sustainability mandates. |
Applications
| DC-DC Converter Output Stage | Automotive Door Module Driver |
|---|---|

IC Role / Device Role / Timing Role: Linear or switched current sink controlling LED string current up to 5A. Use Value: Tight VCE(sat) tolerance (±15mV typical) ensures consistent current regulation across production units without trimming. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN1047ZTA | VCEO = 12V, hFE = 200–400 @ 5A, RθJA = 50°C/W (same footprint) | Higher VCEO margin but lower thermal performance; less suitable for sustained 5A in compact layouts | Select when 12V system headroom is critical and thermal budget permits higher junction rise. |
| MJD127G | VCEO = 100V, IC = 2A, TO-220 package, RθJA = 65°C/W | Higher voltage rating but lower current and inferior thermal resistance; requires heatsink for 2A+ operation | Choose only if legacy TO-220 mounting is mandatory and 100V isolation is required-otherwise inefficient use of board space. |
Compared with ZXTN1047ZTA and MJD127G, FZT1047ATC uniquely balances 5A continuous current, 10V VCEO, and SOT223 thermal performance-making it optimal for space-constrained 12V power stages where efficiency and manufacturability outweigh ultra-high voltage or legacy package needs.

FAQ
What is the maximum safe operating temperature for FZT1047ATC?
The FZT1047ATC has a junction temperature range of –55°C to +150°C. For reliable long-term operation, junction temperature should be kept ≤125°C under steady-state conditions. With RθJA = 41.7°C/W and 3W max power dissipation, this requires ≤60°C ambient temperature on a fully optimized 52mm × 52mm 2oz Cu PCB layout.
Is FZT1047ATC qualified to AEC-Q101?
FZT1047ATC is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified as a standard AEC-Q101 part, Diodes Incorporated confirms it meets all AEC-Q101 test requirements-including HTOL, temperature cycling, and ESD-and can be qualified per customer-specific PPAP scope upon request.
Can FZT1047ATC replace a MOSFET in low-side switching applications?
FZT1047ATC can replace low-voltage N-channel MOSFETs in cost-sensitive, low-frequency (<100 kHz) switching applications where gate drive simplicity is preferred. However, its 25–350mV VCE(sat) is fixed and current-dependent, unlike MOSFETs with RDS(on) that scales linearly-so conduction loss optimization differs significantly.
What is the recommended PCB pad layout for thermal performance?
Diodes specifies a minimum 25mm × 25mm 2oz copper area connected to the collector tab (Pin 3/4) for 1.6W dissipation. For full 3W operation, use 52mm × 52mm 2oz Cu with thermal vias to inner layers. The official SOT223 (DN) pad layout (C1 = 6.40 mm, Y2 = 8.00 mm) must be followed to ensure mechanical reliability and solder joint integrity.
