Product details
Overview
NMB2227AX from Nexperia is a dual NPN/PNP general-purpose transistor pair in a single TSOP6 (SOT457) surface-mount package, rated for 40 V (NPN) and −60 V (PNP) collector-emitter voltage, 600 mA continuous collector current per transistor, and AEC-Q101 qualified for automotive use - deployed in half-bridge motor drivers and complementary switching stages.
For engineers reviewing the NMB2227AX datasheet, NMB2227AX pinout, NMB2227AX application, or NMB2227AX equivalent, key selection criteria include verified dual-transistor polarity matching, guaranteed hFE ≥100 at 150 mA, VCE(sat) ≤1.2 V (NPN) and ≤−1.3 V (PNP) under 150 mA/15 mA drive, thermal resistance of 417 K/W (device-level), and TSOP6 footprint compatibility with automated SMT assembly.
Technical Context
This device integrates two monolithically isolated silicon transistors - TR1 (NPN) and TR2 (PNP) - sharing no internal connection, enabling independent biasing and complementary switching without external pairing. Each transistor supports pulsed operation up to 800 mA peak collector current and exhibits fT of 300 MHz (NPN) and 200 MHz (PNP) at specified test conditions.
Thermal design relies on FR4 PCB mounting with single-sided copper; total power dissipation is derated linearly above 25 °C ambient, reaching zero at 175 °C. Switching performance is characterized with defined test circuits (Figs. 15 & 17), yielding ton ≤35 ns (NPN) and toff ≤365 ns (PNP) under matched drive conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO (TR1/NPN) | 40 V - Maximum safe collector-emitter voltage with base open; defines high-side switch voltage headroom |
| VCEO (TR2/PNP) | −60 V - Absolute maximum reverse-biased collector-emitter voltage; enables low-side switching in −48 V systems |
| IC (continuous) | 600 mA per transistor - Sustained DC current handling capacity; determines minimum trace width and heatsinking needs |
| hFE | 100–300 at IC = 150 mA - Guaranteed DC current gain range; sets base drive resistor sizing for saturation |
| VCE(sat) | ≤1.2 V (NPN), ≤−1.3 V (PNP) at IC/IB = 10 - Confirmed saturation voltage under production-relevant drive; directly impacts conduction loss |
| fT | 300 MHz (NPN), 200 MHz (PNP) - Transition frequency at VCE = 20 V/−20 V; indicates usable bandwidth for small-signal amplification |
| Rth(j-a) (device) | 417 K/W - Junction-to-ambient thermal resistance on standard FR4; used to calculate max junction temperature rise |
Pinout & Package
Package: TSOP6 (SOT457), 6-pin surface-mount plastic package with 0.95 mm pitch, 3.0 × 1.7 mm body, and exposed pad-compatible footprint per Fig. 19 (reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | C2 (collector, TR2/PNP) | High-current output node for PNP transistor; connects to load return path in high-side switch configurations |
| 2 | E1 (emitter, TR1/NPN) | Reference node for NPN transistor; typically tied to ground or low-impedance return in driver stages |
| 3 | C1 (collector, TR1/NPN) | Primary high-current output for NPN transistor; used as switched output in low-side drivers |
| 4 | B1 (base, TR1/NPN) | Control input for NPN transistor; requires current-limited drive to ensure saturation without overdrive |
| 5 | E2 (emitter, TR2/PNP) | Reference node for PNP transistor; commonly connected to supply rail in high-side applications |
| 6 | B2 (base, TR2/PNP) | Control input for PNP transistor; polarity-sensitive drive required to enable conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - eliminates requalification effort for Tier 1 designs |
| Complementary NPN/PNP pairing | Matched hFE and VCE(sat) specs across polarities - simplifies gate drive design in half-bridge topologies |
| Reduced PCB component count | Single-package dual transistor replaces discrete NPN+PNP pairs - saves 2.5 mm² board area and eliminates one placement step |
| TSOP6 footprint compatibility | Standardized 0.95 mm pitch and solder mask layout per Fig. 19 - ensures drop-in replacement in existing SMT lines without stencil revision |
| 600 mA continuous rating | Rated per transistor under FR4 thermal conditions - supports 12 V/24 V solenoid, relay, and LED load switching without external heatsink |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary transistor pair applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201MR6T1G | Same TSOP6 package, but NPN/PNP VCEO = 40 V/−40 V; hFE min = 100 only at IC = 10 mA - lower gain stability at 150 mA | Limited to ≤40 V PNP side; unsuitable for −48 V industrial backplane interfaces | Select only if system VCC ≤40 V and thermal margin >15 °C above max ambient |
| Diodes Incorporated DMMT3904W-7-F | Separate NPN-only SOT-363 device; no integrated PNP - requires two packages and additional routing | Increases PCB area by 3.2 mm² and adds inter-device timing skew risk in bridge configurations | Use only when PNP requirements are decoupled or when legacy NPN-only designs must be extended |
Compared with NSS40201MR6T1G and DMMT3904W-7-F, NMB2227AX delivers higher PNP voltage capability (−60 V vs −40 V), guaranteed gain at full load current, and true single-package complementarity - reducing layout complexity and improving thermal coupling in space-constrained automotive modules.

FAQ
Is NMB2227AX pin-compatible with older revisions of NMB2227A?
Yes - the v.2 datasheet (20251112) confirms identical pinning to v.1, with corrections only to graphic symbol labeling in Table 2. Physical pin 1 index, mechanical outline (Fig. 18), and solder footprint (Fig. 19) remain unchanged, ensuring backward compatibility in existing PCB layouts.
What is the maximum allowable base current for reliable operation?
The absolute maximum peak base current is 200 mA (single pulse, tp ≤ 1 ms), but for continuous DC operation, base current must be limited to maintain IC/IB ≤ 10–20 to ensure VCE(sat) remains within spec. At IC = 600 mA, this corresponds to 60–30 mA steady-state base drive per transistor.
Can NMB2227AX be used in linear amplifier mode?
No - it is optimized for switching applications. The datasheet specifies hFE and VCE(sat) only under pulsed conditions (tp ≤ 300 µs, duty cycle ≤ 2 %), and thermal resistance values assume switching duty cycles. Linear operation risks exceeding Ptot = 300 mW and inducing thermal runaway due to lack of SOA characterization.
Does the AEC-Q101 qualification cover both transistors independently?
Yes - qualification testing was performed on the complete dual-transistor die, with stress applied to each transistor individually per AEC-Q101 test plan. The report confirms compliance for TR1 (NPN) and TR2 (PNP) across HTOL, TC, HAST, and ESD tests, with no shared failure mechanisms reported.
