Product details
Overview
PEMZ1 from Nexperia is an NPN/PNP complementary double transistor in a SOT666 ultra-small surface-mount package (1.6 × 1.2 × 0.55 mm), rated for 40 V VCEO, 100 mA IC, and 300 mW total power dissipation per device. It serves as a compact, space-saving replacement for two discrete SC-75/SC-89 transistors in complementary driver and switching applications.
For engineers reviewing the PEMZ1 datasheet, PEMZ1 pinout, PEMZ1 application, or PEMZ1 equivalent, key selection considerations include its dual-transistor topology, matched thermal behavior in shared package, low-profile soldering compatibility, and verified performance in SMPS and audio driver stages.
Technical Context
The PEMZ1 integrates one NPN (TR1) and one PNP (TR2) transistor in a single monolithic SOT666 package with straight leads enabling self-alignment during reflow. Its complementary pairing supports push-pull operation without inter-device thermal mismatch.
Each transistor operates independently with separate emitter, base, and collector terminals-TR1 uses pins 1 (E1), 2 (B1), 6 (C1); TR2 uses pins 4 (E2), 5 (B2), 3 (C2). DC current gain hFE is ≥120 at VCE = 6 V, IC = 1 mA, Tamb = 25 °C for both polarities.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V maximum - defines safe collector-emitter blocking voltage under open-base conditions for each transistor. |
| IC | 100 mA continuous - sets maximum steady-state collector current per transistor without derating. |
| hFE | ≥120 at 1 mA - ensures reliable current amplification in low-current bias and driver interface circuits. |
| Ptot | 300 mW per device - total dissipation limit when mounted on FR4 PCB with single-sided copper. |
| fT | 100 MHz - usable for signal amplification and switching up to mid-frequency analog and digital control loops. |
| Rth(j-a) | 416 K/W - thermal resistance determines junction temperature rise above ambient under free-air conditions. |
Pinout & Package
SOT666 is a 6-lead ultra-thin surface-mount plastic package measuring 1.6 mm × 1.2 mm × 0.55 mm with 0.5 mm pitch and straight gull-wing leads optimized for reflow soldering and self-alignment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of NPN transistor (TR1) | Low-impedance current sink node for NPN side; connects to ground or low-side load return path. |
| 2 | Base of NPN transistor (TR1) | Control input for NPN switch/amplifier; requires ~5 mA drive for saturation at 50 mA IC. |
| 3 | Collector of PNP transistor (TR2) | High-side current source node; connects to positive rail in complementary output stages. |
| 4 | Emitter of PNP transistor (TR2) | Current source terminal tied to VCC in high-side driver configurations. |
| 5 | Base of PNP transistor (TR2) | Inverted control input; active-low logic compatible with standard CMOS/TTL level shifting. |
| 6 | Collector of NPN transistor (TR1) | Low-side switching node; drives loads connected between VCC and this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual complementary topology | Single-package NPN+PNP pair eliminates layout mismatch and improves thermal tracking in push-pull outputs. |
| Ultra-small footprint | 1.6 × 1.2 mm area - replaces two SC-75 devices while reducing PCB real estate by >40%. |
| Self-aligning lead geometry | Straight gull-wing leads ensure accurate placement and coplanarity during automated reflow assembly. |
| Reflow-optimized thermal design | Rated for reflow only; Rth(j-a) = 416 K/W enables stable operation up to 150 °C junction temperature. |
Applications
| SMPS Complementary Driver | Audio Amplifier Push-Pull Stage |
|---|---|
Use Scenario: Driving gate of high-side/low-side MOSFETs in non-synchronous buck converter. IC Role / Device Role / Timing Role: Dual transistor provides matched turn-on/turn-off timing and reduced propagation skew between drive paths. Use Value: Enables clean dead-time control and minimizes shoot-through risk due to integrated thermal coupling and identical process characteristics. |
Use Scenario: Output stage of Class-AB headphone amplifier delivering ±50 mA into 32 Ω load. IC Role / Device Role / Timing Role: NPN handles positive half-cycle; PNP handles negative half-cycle with symmetrical gain and VCEsat. Use Value: Achieves <200 mV saturation voltage and <1% THD at 1 kHz due to matched hFE and low Cc (1.5–2.2 pF). |
| Low-Voltage Logic Level Shifter | Compact Load Switch Pair |
Use Scenario: Translating 1.8 V GPIO signals to 5 V peripheral interface in battery-powered IoT sensor node. IC Role / Device Role / Timing Role: NPN pulls down; PNP pulls up - forming bidirectional level translator with minimal external components. Use Value: Eliminates need for dedicated level-shifting IC; supports 10 MHz toggle rate via fT = 100 MHz and low capacitance. |
Use Scenario: Dual-rail power management in portable medical device requiring independent enable control of analog and digital subsystems. IC Role / Device Role / Timing Role: Each transistor acts as discrete load switch with base-driven on/off control and built-in current limiting. Use Value: Reduces BOM count by two transistors and saves 2.2 mm² PCB area versus discrete SC-75 implementation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC846BPDW1T1G | Same SOT-363 package, but lower VCEO (65 V NPN / 65 V PNP) and higher hFE range (200–450). | Better suited for higher-voltage linear regulation; less optimal for low-VCC fast-switching due to larger die size and higher Cc. | Select when higher gain stability across IC range is required, and board space allows for marginally larger footprint. |
| MBT3904DW1T1G | Lower power rating (200 mW), smaller hFE (100 min), and no guaranteed matching between NPN/PNP units. | Acceptable for non-critical bias networks but unsuitable for precision push-pull where gain symmetry matters. | Choose only for cost-sensitive, non-matched applications where thermal coupling and timing alignment are not design constraints. |
Compared with BC846BPDW1T1G and MBT3904DW1T1G, PEMZ1 offers superior thermal coupling, tighter parametric matching, and optimized reflow compatibility in the smallest available SOT666 form factor-making it preferred for space-constrained, high-reliability driver designs.

FAQ
What is the maximum operating temperature for PEMZ1?
The PEMZ1 has a maximum junction temperature (Tj) of 150 °C and a storage temperature range of −65 °C to +150 °C. When mounted on an FR4 PCB with single-sided copper, its thermal resistance from junction to ambient is 416 K/W, meaning a 300 mW power dissipation results in a 125 K rise above ambient-so operation up to +25 °C ambient ensures safe Tj limits.
Can PEMZ1 be used in automotive applications?
No. The PEMZ1 is explicitly marked as non-automotive qualified in its revision history and legal disclaimers. It has not undergone AEC-Q101 stress testing or automotive-grade qualification, and Nexperia expressly excludes liability for use in safety-critical or life-support systems-including automotive ECUs, ADAS modules, or powertrain controls.
How does the SOT666 package differ from SOT-363?
SOT666 measures 1.6 × 1.2 × 0.55 mm with 0.5 mm pitch and straight leads, while SOT-363 is slightly larger (2.1 × 1.25 × 0.95 mm) and uses bent gull-wing leads. SOT666 enables finer pitch routing, better coplanarity, and improved self-alignment during reflow-critical for high-density PCBs where mechanical placement accuracy is limited.
Is there a recommended footprint for PEMZ1 reflow soldering?
Yes. Nexperia specifies a reflow footprint with 0.45 mm × 0.3 mm solder pads (4 per side), 0.55 mm spacing between pad rows, and 2.75 mm × 2.45 mm overall land pattern. This layout ensures sufficient solder volume for mechanical strength and thermal conduction while preventing bridging-validated for lead-free reflow profiles per J-STD-020.
