Product details
Overview
RN2412,LXHF from Toshiba Electronic Devices & Storage Corporation is a silicon PNP epitaxial bipolar transistor with integrated bias resistors (PCT process), rated for VCEO = -50 V, IC = -100 mA, and hFE = 120–400 at IC = -1 mA. It operates as a compact switching device in low-voltage driver and interface circuits, supporting automotive-grade applications per AEC-Q101 qualification.
For engineers reviewing the RN2412,LXHF datasheet, RN2412,LXHF pinout, RN2412,LXHF application, or RN2412,LXHF equivalent, key selection criteria include its built-in R1 input resistor (47 kΩ typ.), low VCE(sat) of -0.3 V at IC = -5 mA/IB = -0.25 mA, S-Mini package compatibility, and AEC-Q101 compliance for automotive use cases.
Technical Context
This PNP digital transistor integrates a single 47 kΩ base-emitter bias resistor (R1), eliminating external bias components and simplifying PCB layout for level-shifting and logic interfacing. Its PCT (Planar Complementary Transistor) epitaxial structure ensures stable hFE across temperature and consistent VCE(sat) performance under switching loads.
The device supports DC switching up to 100 mA with fT = 15.4 MHz (typ.) and Cob = 3 pF (typ.), enabling reliable operation in 100 kHz–1 MHz inverter and signal-gating applications without parasitic oscillation concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -50 V - Maximum allowable collector-emitter voltage before breakdown; defines safe operating range in high-side switch configurations. |
| IC | -100 mA - Continuous collector current rating; supports driving LEDs, relays, or small MOSFET gates without derating at 25°C. |
| hFE | 120–400 - DC current gain range at VCE = -5 V, IC = -1 mA; enables predictable base drive sizing for saturation control. |
| VCE(sat) | -0.3 V (max) at IC = -5 mA / IB = -0.25 mA - Low saturation voltage minimizes power loss and self-heating in on-state switching. |
| R1 | 47 kΩ (typ.) - Integrated base resistor value; eliminates need for external bias network and reduces BOM count by one component. |
| fT | 15.4 MHz (typ.) - Transition frequency confirms suitability for medium-speed digital switching up to ~1–2 MHz. |
| Cob | 3 pF (typ.) - Collector-base output capacitance; contributes to fast turn-off response and limits high-frequency ringing. |
Pinout & Package
S-Mini package (12 mg typ., JEDEC TO-236 compatible outline), surface-mount, 3-pin plastic molded case with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Input terminal connected internally to R1; accepts TTL/CMOS-compatible logic-level drive without external resistor. |
| 2 | Emitter | Common reference node for PNP configuration; tied to higher potential (e.g., VCC) in high-side switch topologies. |
| 3 | Collector | Output terminal sourcing current to load; connects to load return path (e.g., ground) in standard switching arrangements. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronic modules including body control units and lighting drivers requiring extended temperature and reliability assurance. |
| Integrated R1 bias resistor | 47 kΩ typ. reduces external component count by one, cuts PCB area, and improves assembly yield in high-volume production. |
| Low VCE(sat) | -0.3 V max at rated switching current ensures <15 mW conduction loss, minimizing thermal stress in sealed enclosures. |
| Complementary pairing | Direct counterpart to RN1412 (NPN) enables matched push-pull or inverter stage design with consistent gain and timing behavior. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSV2412MUT1G | Same S-Mini package; R1 = 47 kΩ (typ.), but hFE min = 100 and VCE(sat) max = -0.4 V at same test condition. | Qualified to AEC-Q101 but lacks explicit automotive-use marking in orderable part number; general-purpose variant. | Select when cost sensitivity outweighs automotive traceability requirements and slightly higher VCE(sat) is acceptable. |
| UMT2412T106 | Same pinout and R1 value; however, IC rating is -50 mA (vs. -100 mA), limiting drive capability for heavier loads. | Not AEC-Q101 qualified; intended for consumer electronics only. | Choose for non-automotive, low-current (<50 mA) interface tasks where footprint and BOM reduction remain priorities. |
Compared with RN2412,LXHF, NSV2412MUT1G offers identical form factor and biasing but lower hFE guarantee and relaxed saturation voltage, while UMT2412T106 trades current capacity and automotive qualification for lower unit cost in commercial-grade designs.

FAQ
What is the AEC-Q101 qualification status of RN2412,LXHF?
RN2412,LXHF is explicitly listed as AEC-Q101 qualified in Toshiba's official orderable part number table. This certification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life-validating its suitability for automotive electronic control units and lighting systems. The LXHF suffix denotes the automotive-grade tape-and-reel packaging variant meeting PPAP requirements.
Does RN2412,LXHF require an external base resistor?
No, RN2412,LXHF does not require an external base resistor. It integrates a 47 kΩ (typ.) resistor between base and emitter (R1), enabling direct connection of logic-level inputs to the base terminal. This internal resistor allows the RN2412,LXHF to function as a true "digital transistor" with simplified drive circuitry and reduced PCB component count.
What is the maximum continuous collector current for RN2412,LXHF?
The absolute maximum continuous collector current (IC) for RN2412,LXHF is -100 mA at Ta = 25°C. Derating is required above 25°C per the datasheet's thermal characteristics curve; at 100°C ambient, the usable IC drops to approximately -60 mA to maintain junction temperature below 150°C. This rating supports driving typical indicator LEDs, small relays, and MOSFET gates in compact systems.
How does RN2412,LXHF differ from RN2413,LXHF?
RN2412,LXHF and RN2413,LXHF share identical package, pinout, and AEC-Q101 qualification, but differ in hFE and fT. RN2412,LXHF has hFE = 120–400 and fT = 15.4 MHz (typ.), while RN2413,LXHF offers hFE = 200–400 and fT = 22 MHz (typ.). RN2412,LXHF is optimized for general-purpose switching with broader gain tolerance; RN2413,LXHF targets higher-speed applications needing tighter hFE consistency and faster response.
What is the S-Mini package dimension and lead finish for RN2412,LXHF?
RN2412,LXHF uses the S-Mini package (JEDEC TO-236AB equivalent), measuring 2.9 × 1.3 × 0.9 mm (L × W × H) with gull-wing leads. The LXHF suffix indicates lead-free (Pb-free), halogen-free, and RoHS-compliant matte tin plating over copper leads, verified per Toshiba's environmental compliance documentation and shipped in dry-packed tape-and-reel format.
