Product details
Overview
RN2304(TE85L,F) from Toshiba Electronic Devices & Storage Corporation is a silicon PNP epitaxial bipolar transistor with integrated bias resistors (R1 = 47 kΩ, R2 = 47 kΩ), designed for low-power switching and interfacing in compact PCB layouts. It operates with VCEO = −50 V, IC = −5 mA max, and hFE = 80 (min) at IC = −5 mA, IB = −0.25 mA, and is qualified to AEC-Q101 for automotive-grade reliability.
For engineers reviewing the RN2304(TE85L,F) datasheet, RN2304(TE85L,F) pinout, RN2304(TE85L,F) application, or RN2304(TE85L,F) equivalent, key selection criteria include its USM package footprint, built-in resistor ratio (R1/R2 = 1.0), VCE(sat) ≤ −0.15 V at IC = −5 mA, and compatibility with 3.3 V/5 V logic-level drive circuits.
Technical Context
This PNP digital transistor integrates two precision bias resistors (R1 = R2 = 47 kΩ) directly into the USM package, eliminating external base resistors and reducing component count in level-shifting and load-switching nodes. Its −50 V collector-base and collector-emitter ratings support operation in 24 V industrial control rails and automotive 12 V systems with margin.
The device delivers hFE ≥ 80 at −5 mA collector current and exhibits fT = 80 MHz (typ.), enabling stable switching up to ~100 kHz with minimal propagation delay. VI(ON) ≤ −1.5 V and VI(OFF) ≥ −0.5 V ensure robust noise immunity and clean turn-on/turn-off behavior under varying supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Supports safe operation in 24 V DC systems with transient margin. |
| IC(max) | −5 mA: Suitable for driving LEDs, small relays, and logic-level interface loads. |
| hFE(min) | 80 at IC = −5 mA, IB = −0.25 mA: Ensures predictable saturation with low base drive current. |
| VCE(sat)(max) | −0.15 V at IC = −5 mA: Minimizes power loss (<0.75 mW) in saturated switch mode. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSV2304MW6T1G | R1 = 47 kΩ, R2 = 47 kΩ; same USM package; VCEO = −50 V, but hFE min = 60 (vs. 80). | Suitable for less critical switching where lower current gain is acceptable. | Prefer RN2304(TE85L,F) when guaranteed hFE ≥ 80 is required for marginal drive conditions. |
| DTC124EKAT146 | Same R1/R2 = 47 kΩ, but NPN polarity; SOT-23 package (larger than USM); VCEO = 50 V. | Requires circuit redesign for high-side vs. low-side topology; not drop-in. | Select RN2304(TE85L,F) for PNP-specific roles like high-side load switching or complementary pairing with RN1304. |
Compared with NSV2304MW6T1G and DTC124EKAT146, RN2304(TE85L,F) offers higher guaranteed hFE and AEC-Q101 qualification in the smallest USM footprint-making it optimal for automotive and miniaturized industrial interfaces where gain margin and reliability are prioritized over generic substitution.

FAQ
What is the maximum collector current rating for RN2304(TE85L,F)?
The absolute maximum collector current for RN2304(TE85L,F) is −5 mA under continuous DC operation at Ta = 25 °C. This rating reflects its role as a signal-level switch-not a power device-and aligns with typical LED driver and logic interface loads. Exceeding this value risks thermal runaway or parametric shift. The RN2304(TE85L,F) datasheet specifies IC = −5 mA as the test condition for hFE and VCE(sat) measurements.
Is RN2304(TE85L,F) pin-compatible with other RN23xx series transistors?
Yes, all RN23xx series transistors-including RN2304(TE85L,F)-share identical USM package dimensions and pin assignment (Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector). This allows board-level substitution across the family when bias resistor values match circuit requirements. However, R1 and R2 differ per variant (e.g., RN2301 uses 4.7 kΩ), so electrical behavior varies even with identical pinout.
Does RN2304(TE85L,F) support automotive applications?
Yes, RN2304(TE85L,F) is explicitly qualified to AEC-Q101 and listed in Toshiba's orderable part number table for automotive use. It meets stress testing requirements for temperature cycling, humidity, and mechanical shock applicable to body electronics and lighting control modules. The RN2304(TE85L,F) datasheet confirms "Automotive Use" status in its packaging table.
What is the input voltage threshold (VI(ON)) for RN2304(TE85L,F)?
The VI(ON) parameter for RN2304(TE85L,F) is −1.5 V (max) at IC = −5 mA, meaning the transistor fully saturates when the base-emitter input reaches or exceeds −1.5 V. This threshold ensures reliable turn-on from standard 3.3 V or 5 V logic families with inverted drive. The RN2304(TE85L,F) datasheet defines VI(ON) under VCE = −0.2 V, IC = −5 mA test conditions.
How does the R1/R2 ratio affect circuit design with RN2304(TE85L,F)?
RN2304(TE85L,F) has R1 = R2 = 47 kΩ, yielding an R1/R2 ratio of 1.0-ideal for symmetrical input thresholds in noise-immune switching applications. This ratio sets VI(OFF) ≥ −0.5 V and VI(ON) ≤ −1.5 V, providing a clean 1.0 V hysteresis window. Unlike variants with unequal resistors (e.g., RN2305: R1 = 2.2 kΩ, R2 = 47 kΩ), the RN2304(TE85L,F) supports balanced logic-level translation without external tuning.
