Product details
Overview
RN2302,LXHF from Toshiba Electronic Devices & Storage Corporation is a silicon PNP epitaxial bipolar transistor with integrated bias resistors (R1 = 10 kΩ, R2 = 10 kΩ), designed for switching and interfacing in compact DC-DC converters, automotive body control modules, and logic-level signal translation circuits.
For engineers reviewing the RN2302,LXHF datasheet, RN2302,LXHF pinout, RN2302,LXHF application, or RN2302,LXHF equivalent, this AEC-Q101-qualified discrete device supports reliable low-power switching at VCEO = −50 V, IC = −5 mA, and VCE(sat) ≤ −1.2 V under standard test conditions.
Technical Context
The RN2302,LXHF integrates two precision on-chip resistors (R1 = R2 = 10 kΩ) to form a monolithic bias network, eliminating external base resistors and reducing PCB footprint. Its PCT process ensures stable hFE (50–200) and low ICEO (≤ −500 nA) across temperature.
As a complementary part to the RN1302 series, it enables matched push-pull configurations in level-shifting and inverter stages. The USM package supports high-density mounting while maintaining thermal performance up to Tj = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; suitable for 24 V automotive supply rail switching. |
| IC | −5 mA: Continuous collector current rating; supports logic-driven load switching without external current limiting. |
| hFE | 50–200: DC current gain range at IC = −5 mA, IB = −0.25 mA; enables predictable base drive sizing. |
| VCE(sat) | ≤ −1.2 V at IC = −5 mA, IB = −0.25 mA; ensures low conduction loss in saturated switch operation. |
| R1 / R2 | 10 kΩ / 10 kΩ: Matched internal base bias resistors; eliminates need for two external resistors in standard BRT configuration. |
| fT | 7 MHz: Transition frequency; sufficient for <1 MHz digital switching and moderate-speed interface applications. |
| Cob | 6 pF at VCB = −10 V; limits high-frequency coupling in noise-sensitive analog-digital boundary circuits. |
Pinout & Package
Package: USM (Ultra Small Mold), 3-pin surface-mount, 0.9 × 0.6 × 0.4 mm, 6.0 mg typical weight, RoHS-compliant, AEC-Q101 qualified for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Connected internally to R1 and R2; accepts logic-level input to enable transistor turn-on/turn-off without external bias network. |
| 2 | Emitter | PNP emitter terminal; tied to higher potential rail (e.g., VCC); current flows from emitter to collector when active. |
| 3 | Collector | Output node for switched load; connects to grounded or low-side loads in high-side switching topology. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including body electronics and interior lighting control modules. |
| Integrated R1/R2 = 10 kΩ | Reduces bill-of-materials count by two resistors and associated placement area; improves assembly yield and reliability. |
| Low VCE(sat) ≤ −1.2 V | Minimizes power dissipation in saturated mode, enabling efficient operation in battery-powered systems. |
| Complementary pairing with RN1302 | Enables symmetrical NPN/PNP driver pairs in H-bridge and totem-pole output stages without design mismatch. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP bias-resistor transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RN2302,LF | Same electrical specs and USM package; halogen-free but not AEC-Q101 qualified. | Restricted to general-purpose industrial or consumer applications; not approved for automotive ECUs. | Select RN2302,LF only when automotive qualification is unnecessary and halogen-free compliance is required. |
| NSV2302MW6T1G | PNP BRT with R1 = R2 = 10 kΩ, SOT-363 package, AEC-Q101 qualified; slightly larger footprint (2.0 × 1.25 mm vs. USM's 0.9 × 0.6 mm). | Compatible in function but requires PCB layout revision due to different pinout (SOT-363 pin 1 = Emitter, pin 2 = Base, pin 3 = Collector) and larger size. | Choose NSV2302MW6T1G only when USM package availability is constrained and board space allows SOT-363 rework. |
Compared with RN2302,LF and NSV2302MW6T1G, the RN2302,LXHF uniquely combines AEC-Q101 qualification, ultra-compact USM packaging, and exact 10 kΩ/10 kΩ resistor matching-making it optimal for space-constrained automotive modules where qualification and miniaturization are jointly critical.

FAQ
What is the package type and dimensions of RN2302,LXHF?
RN2302,LXHF uses the USM (Ultra Small Mold) package: 0.9 mm × 0.6 mm × 0.4 mm, with 3 terminals in single-row SMT configuration. It weighs 6.0 mg typical and features halogen-free molding compound compliant with J-STD-020 moisture sensitivity level 1. This package enables high-density placement in space-constrained automotive and portable electronics designs.
Is RN2302,LXHF AEC-Q101 qualified?
Yes, RN2302,LXHF is explicitly listed as AEC-Q101 qualified in Toshiba's official orderable part number table. It meets stress testing requirements for temperature cycling, humidity bias, and mechanical shock applicable to automotive electronic components used in non-safety-critical systems such as door modules and lighting controls.
What are the exact bias resistor values inside RN2302,LXHF?
RN2302,LXHF contains two precisely trimmed on-die resistors: R1 = 10 kΩ (base-to-input) and R2 = 10 kΩ (base-to-emitter). These values are confirmed in Toshiba's "Bias Resistor Values" table and verified across production lots to ±15% tolerance, enabling consistent turn-on behavior without external component variation.
How does RN2302,LXHF differ from RN2302,LF?
RN2302,LXHF and RN2302,LF share identical electrical characteristics and USM packaging, but RN2302,LXHF is designated for automotive use with full AEC-Q101 qualification and halogen-free construction, whereas RN2302,LF is rated for general-purpose applications without automotive qualification. Both are manufactured by Toshiba and pin-compatible.
Can RN2302,LXHF replace a discrete PNP transistor plus two resistors?
Yes, RN2302,LXHF directly replaces a standalone PNP transistor (e.g., 2SA1015) plus two 10 kΩ base bias resistors in standard BRT configurations. Its integrated R1/R2 network maintains identical DC biasing behavior while reducing component count, solder joints, and layout area-verified in Toshiba's application notes for inverter and switching circuits.
