Product details

Overview

NMB2227AH 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 NMB2227AH datasheet, NMB2227AH pinout, NMB2227AH application, or NMB2227AH equivalent, this device supports high-current complementary switching with verified thermal resistance (417 K/W per device), low V_CE(sat) (≤1.2 V at I_C = 150 mA), and fast switching (t_off ≤ 365 ns for PNP), making it suitable for space-constrained DC-DC and motor control PCBs.

Technical Context

The NMB2227AH integrates matched NPN (TR1) and PNP (TR2) transistors on one die, sharing thermal coupling and enabling precise complementary operation without discrete layout mismatch. Its bipolar junction architecture delivers linear amplification and saturated switching across −55 °C to 150 °C ambient.

Each transistor features independent base-emitter and collector-base junctions with specified cut-off currents (ICBO ≤ 10 nA for NPN, ≤ −10 µA at T_j = 125 °C for PNP), validated f_T of 300 MHz (NPN) and 200 MHz (PNP), and defined saturation behavior under pulsed conditions (tp ≤ 300 µs, δ ≤ 0.02).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO (NPN)	40 V - Maximum safe collector-emitter voltage with open base; defines upper rail limit in low-side switch designs.
V_CEO (PNP)	−60 V - Absolute maximum reverse collector-emitter voltage; enables higher-voltage high-side switching in bridge topologies.
I_C (continuous)	600 mA per transistor - Sustained current handling capability at T_amb ≤ 25 °C on FR4 PCB; supports 12 V/24 V automotive loads.
h_FE	100–300 (NPN & PNP) - DC current gain range at V_CE = ±10 V, I_C = ±150 mA; ensures reliable base drive sizing for saturation.
V_CE(sat)	≤1.2 V (NPN), ≤−1.3 V (PNP) at I_C = ±150 mA / I_B = ±15 mA - Low saturation voltage minimizes conduction loss in switching applications.
t_off	≤250 ns (NPN), ≤365 ns (PNP) - Measured turn-off time under defined test conditions; critical for PWM frequency selection up to ~1 MHz.
R_th(j-a)	417 K/W (per device) - Junction-to-ambient thermal resistance on standard FR4 PCB; determines max power dissipation before derating.

Pinout & Package

Package: TSOP6 (SOT457), 6-lead surface-mount plastic package with 0.95 mm pitch, 3.0 × 1.7 mm footprint, and exposed pad-compatible layout per Fig. 19 (reflow soldering).

Pin/Terminal	Circuit Role	Design Meaning
1	C2	Collector of TR2 (PNP transistor); connects to high-side load or supply rail in complementary configurations.
2	E1	Emitter of TR1 (NPN transistor); common emitter node in push-pull output stages or grounded reference point.
3	C1	Collector of TR1 (NPN transistor); connects to low-side load or ground return path in half-bridge circuits.
4	B1	Base of TR1 (NPN transistor); driven by microcontroller GPIO or level-shifted logic to enable low-side switching.
5	E2	Emitter of TR2 (PNP transistor); typically tied to V_CC or regulated supply in high-side driver applications.
6	B2	Base of TR2 (PNP transistor); requires active pull-down or dedicated gate driver for controlled high-side turn-on.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive-grade reliability including temperature cycling, humidity testing, and ESD robustness per JESD22 standards.
Complementary NPN/PNP pairing	Matched h_FE, V_CE(sat), and switching timing within one package reduces layout asymmetry and improves bridge balance.
High current density	600 mA per transistor in 3.0 × 1.7 mm footprint - enables compact motor driver IC replacement without external heatsinking.
Low thermal resistance	417 K/W (device-level) - allows sustained 300 mW dissipation at 25 °C ambient, supporting continuous-duty 12 V solenoid or fan control.
Pulsed switching performance	t_on ≤ 35 ns (NPN), t_off ≤ 365 ns (PNP) - supports efficient PWM operation up to 1 MHz in Class-D audio or SMPS pre-drivers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar complementary bipolar transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSS40201MR6T1G	Same SOT-457 package, but NPN/NPN dual; lacks PNP complement; V_CEO = 40 V only; h_FE min = 100 at I_C = 10 mA.	Not suitable for true complementary switching; requires external PNP for high-side drive.	Select only if design uses NPN-only topology with external high-side FET or optocoupler isolation.
Diodes Incorporated DMMT3904W-7-F	NPN-only dual in SOT-363; no PNP; V_CEO = 40 V; I_C = 200 mA; h_FE = 100–300; smaller 2.2 × 1.35 mm footprint.	Insufficient current rating for 600 mA loads; limited to signal-level or low-power switching.	Use only for biasing, logic translation, or pre-driver stages-not for main power switching.

Compared with NSS40201MR6T1G and DMMT3904W-7-F, the NMB2227AH uniquely delivers matched NPN/PNP characteristics in one AEC-Q101-qualified package with 600 mA rating and 417 K/W thermal resistance - eliminating layout complexity and thermal mismatch inherent in dual-discrete solutions.

FAQ

What is the maximum operating junction temperature for NMB2227AH?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the limiting values table. Operation above this threshold risks permanent degradation of h_FE and increased leakage. Derating begins at T_amb > 25 °C per the 417 K/W thermal resistance curve, with full power (300 mW) permitted only at ambient ≤ 25 °C on standard FR4 PCB.

Can NMB2227AH be used in linear amplifier mode?

Yes - its specified h_FE (100–300), low V_CE(sat), and characterized f_T (300 MHz NPN / 200 MHz PNP) support Class-A and Class-AB small-signal amplification. However, thermal limits restrict continuous linear operation to ≤100 mW at 25 °C ambient due to R_th(j-a) = 417 K/W; forced-air or heatsink mounting is required for higher dissipation.

Is the pinout compatible with other TSOP6-packaged dual transistors?

No - NMB2227AH uses a proprietary pin assignment (C2–E1–C1–B1–E2–B2) optimized for complementary bridge routing. It is not pin-compatible with generic dual-NPN TSOP6 devices like PBSS4041T or MMDT3904. Layout must follow Figure 2 (p. 2) of the Nexperia datasheet to avoid functional misconnection.

Does NMB2227AH require external base resistors in switching applications?

Yes - base current must be limited to prevent damage. For I_C = 600 mA and h_FE = 100, minimum I_B = 6 mA is required; typical design uses 10 kΩ pull-up/pull-down with 3.3 V/5 V logic. The datasheet specifies I_BM peak = 200 mA, so resistor values must ensure I_B stays below this during transient conditions.
