Product details
Overview
PZT4403 from Nexperia is a PNP bipolar junction transistor designed for medium-power switching and linear amplification in SMT applications. It delivers −40 V VCEO, −600 mA IC, DC current gain (hFE) of 30–300 at −1 V VCE, −150 mA IC, and −750 mV VCE(sat) at −500 mA IC / −50 mA IB. It is used in DC-DC converter control stages, relay drivers, and LED load switches on industrial PCBs.
For engineers reviewing the PZT4403 datasheet, PZT4403 pinout, PZT4403 application, or PZT4403 equivalent, key selection criteria include verified PNP polarity, SOT223 thermal performance (Rth(j-sp) = 25 K/W), low saturation voltage under pulsed 500 mA loads, and compatibility with FR4 PCBs using standard or enhanced heatsink footprints.
Technical Context
This discrete PNP BJT operates in active and saturation regions for analog amplification and hard-switching functions. Its dual-collector pin configuration (Pins 2 & 4) enables higher power dissipation via shared thermal path to the heatsink pad, supporting up to 900 mW at Tamb ≤ 25 °C with 1 cm² collector pad.
Switching performance is characterized by ton = 40 ns, toff = 350 ns, and fT = 200 MHz at −10 V VCE, −20 mA IC, making it suitable for <1 MHz digital logic interfacing and PWM-driven loads where base drive efficiency and turn-off speed are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −40 V: Maximum safe collector-emitter voltage with open base; defines upper rail limit in high-side switch designs. |
| IC | −600 mA continuous: Rated collector current for sustained conduction without thermal runaway on standard FR4. |
| hFE | 30–300 at −1 V VCE: Wide DC gain range supports both low-base-drive switching and precision current mirror configurations. |
| VCE(sat) | −750 mV at −500 mA IC/−50 mA IB: Low saturation voltage minimizes power loss in high-current switching nodes. |
| Rth(j-sp) | 25 K/W: Thermal resistance from junction to solder point with 1 cm² copper pad; enables predictable thermal design for SMT layout. |
| fT | 200 MHz: Transition frequency confirms usable bandwidth for fast digital interface and RF bias applications up to ~100 MHz. |
| toff | 350 ns: Turn-off time under defined test conditions (IBoff = +15 mA); determines minimum PWM dead-time in half-bridge drivers. |
Pinout & Package
The PZT4403 is housed in an SC-73 (SOT223) plastic surface-mount package measuring 6.5 mm × 3.5 mm × 1.65 mm, featuring an exposed collector thermal pad (Pin 2 and Pin 4 electrically tied) for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input node; requires −15 mA peak base current for full saturation at −500 mA collector load. |
| 2 | Collector (C) | Main high-current output terminal; internally connected to thermal pad for direct PCB heatsinking. |
| 3 | Emitter (E) | Reference node for PNP operation; tied to system ground or positive rail depending on switch topology. |
| 4 | Collector (C) | Second collector terminal, electrically identical to Pin 2; provides redundant connection to thermal pad and improves solder joint reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-collector thermal architecture | Two collector pins (2 & 4) bonded to a common internal metal slug, enabling 900 mW power dissipation with optimized PCB copper area. |
| Low VCE(sat) at high IC | −750 mV at −500 mA ensures <0.4 W conduction loss per device in 12 V load-switching applications. |
| High-speed switching | 350 ns toff and 40 ns ton support PWM frequencies up to 1 MHz with minimal overlap loss in synchronous rectifiers. |
| Robust absolute ratings | −40 V VCEO, −600 mA IC, and 150 °C Tj allow operation in 24 V industrial control systems with margin. |
| Standardized SOT223 footprint | Compatible with JEDEC MO-178AA reflow profiles and wave-soldering footprints (Fig. 6 & 7), ensuring manufacturability across EMS providers. |
Applications
| DC-DC Converter Switch | Industrial Relay Driver |
|---|---|
|
Use Scenario: High-side switch in non-synchronous buck converter feedback loop controlling 12 V to 5 V conversion for microcontroller power rails. IC Role / Device Role / Timing Role: PNP BJT configured as saturated switch, turning on/off energy transfer to output inductor based on PWM signal from controller IC. Use Value: −750 mV VCE(sat) limits conduction loss to 375 mW at 500 mA, improving efficiency over alternatives with >1 V saturation. |
Use Scenario: Driving 24 V DC coil relays in programmable logic controller (PLC) output modules with opto-isolated inputs. IC Role / Device Role / Timing Role: Medium-power interface transistor translating isolated logic-level signals into sufficient coil current (≤600 mA). Use Value: Verified 300 ns storage time (ts) enables clean turn-off during rapid state transitions, preventing contact chatter in safety-critical outputs. |
| LED Load Switch | Linear Current Regulator |
|
Use Scenario: Constant-current driver for high-brightness white LEDs in industrial signage, powered from 24 V supply with PWM dimming. IC Role / Device Role / Timing Role: PNP emitter-follower configured as adjustable current sink, modulated via base voltage reference. Use Value: hFE ≥ 100 at −10 mA ensures stable regulation with <5% current drift across temperature when paired with 1% sense resistor. |
Use Scenario: Precision current source for sensor biasing in analog front-end circuits, e.g., powering RTD or photodiode transimpedance stages. IC Role / Device Role / Timing Role: Linear-mode BJT operating in active region, delivering stable −150 mA output with low thermal coefficient. Use Value: Rth(j-a) = 139 K/W with enhanced pad allows stable 150 mA operation at 75 °C ambient without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT4403 | Same die in SOT-23 package; lower Ptot (350 mW), no dual-collector thermal pad, Rth(j-a) = 350 K/W. | Limited to ≤200 mA continuous loads; unsuitable for 500 mA switching without significant derating. | Select only for space-constrained boards where thermal budget permits 60% lower current rating. |
| PN2907A | TO-92 through-hole package; VCEO = −60 V, but hFE min = 100 only at −150 mA; no pulsed switching characterization. | Not qualified for automated SMT assembly; lacks transient thermal data for PWM use cases. | Prefer for prototyping or low-volume through-hole builds where thermal management is passive and frequency <100 kHz. |
Compared with MMBT4403 and PN2907A, the PZT4403 uniquely combines SOT223 manufacturability, dual-collector thermal robustness, and verified 500 mA pulsed switching performance-making it the only option rated for production-grade 24 V industrial load switching with ≤1 µs timing control.

FAQ
What is the maximum continuous collector current for PZT4403 under standard PCB conditions?
The PZT4403 supports −600 mA continuous collector current when mounted on an FR4 PCB with single-sided copper and standard SOT223 footprint (Rth(j-a) = 209 K/W). Derating is required above 25 °C ambient; at 70 °C, max IC drops to approximately −420 mA to maintain Tj ≤ 150 °C.
Can PZT4403 be used in linear amplifier configurations?
Yes-its hFE of 30–300 across −0.1 mA to −150 mA IC, combined with low VCE(sat) and stable fT = 200 MHz, supports Class-A and emitter-follower linear amplification. Designers must ensure proper biasing and heatsinking, as linear operation increases power dissipation versus switching mode.
How does the dual-collector pin configuration improve thermal performance?
Pins 2 and 4 are internally shorted to the same collector metallization and thermal slug. This doubles solder joint area and improves heat transfer to the PCB copper pad, reducing Rth(j-sp) to 25 K/W (vs. ~40 K/W typical for single-collector SOT223 devices), enabling 900 mW dissipation with a 1 cm² pad.
Is PZT4403 automotive-qualified?
No-this device is not automotive-qualified. The datasheet explicitly states it is "non-automotive qualified" and lacks AEC-Q101 stress testing, extended temperature validation, or PPAP documentation. It is intended for industrial, commercial, and consumer applications only.
