Product details
Overview
NHDTC114EUF from Nexperia is an 80 V, 100 mA NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, integrating 10 kΩ input and 10 kΩ feedback bias resistors. It functions as a single-chip digital switch for IC input control and low-power load switching, with VCEO = 80 V, IO = 100 mA, and VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA.
For engineers reviewing the NHDTC114EUF datasheet, NHDTC114EUF pinout, NHDTC114EUF application, or NHDTC114EUF equivalent, this part serves as a space- and BOM-optimized replacement for discrete base-resistor + transistor solutions in digital logic interfacing, microcontroller GPIO buffering, and low-current switching circuits where simplified layout and AEC-Q101-qualified reliability are required.
Technical Context
This NPN RET integrates two monolithic silicon resistors (R1 = R2 = 10 kΩ ±30%) directly connected to the base terminal, enabling direct logic-level drive without external bias components. Its internal structure eliminates need for separate base current limiting and pull-down networks.
The device operates with guaranteed VCEO = 80 V and IO = 100 mA under DC conditions, supports VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.15 V at IC = 10 µA, and maintains hFE ≥ 50 at VCE = 5 V / IC = 10 mA - confirming robust digital switching behavior across -40 °C to +150 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V industrial bus and 48 V telecom auxiliary rails. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 / R2 | 10 kΩ / 10 kΩ - Integrated base bias resistors eliminate two external components and reduce PCB area by ~1.2 mm². |
| VCE(sat) | ≤ 100 mV at IC = 10 mA / IB = 0.5 mA - Ensures <10 mW conduction loss and minimal voltage drop in active switching state. |
| hFE | ≥ 50 at VCE = 5 V / IC = 10 mA - Guarantees reliable saturation with standard MCU GPIO drive strength (e.g., 5 V/20 mA). |
| Tj(max) | 150 °C - Junction temperature limit supporting operation in sealed enclosures and high-ambient industrial environments. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.15 mm × 0.45 mm body, 3-terminal leadframe, JEDEC-compliant footprint with 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Internal connection to R1 and R2 network; accepts TTL/CMOS logic levels directly without series resistor. |
| 2 | GND (emitter) | Emitter tied to ground reference; provides return path for both input and output currents. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode, relay coil) referenced to positive rail. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-resistor network | Eliminates need for external base biasing components, reducing bill-of-materials count by two passive parts. |
| 80 V breakdown rating | Supports operation on 24 V and 48 V power domains without derating or additional protection circuitry. |
| 100 mA continuous output | Drives typical indicator LEDs (20 mA), optocoupler inputs (10–15 mA), and small-signal relays (≤50 mA coil). |
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, HAST, and ESD testing per JESD22 standards. |
Applications
| Microcontroller GPIO Buffering | LED Indicator Driver |
|---|---|
|

IC Role / Device Role / Timing Role: Current-limited switch sourcing precise 5–10 mA into optocoupler LED anode. Use Value: Built-in R1/R2 ensures consistent forward current without tolerance stacking from discrete resistors. |
Use Scenario: Activating 5 V or 12 V reed relays or miniature signal relays in PLC I/O modules and test equipment. IC Role / Device Role / Timing Role: Low-saturation switch delivering up to 100 mA to relay coil while maintaining fast turn-on/turn-off. Use Value: Achieves ton/toff < 100 ns due to low Cc = 2.5 pF and integrated base charge control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC846B,115 | Discrete NPN BJT without integrated resistors; requires external 10 kΩ base resistor and 10 kΩ emitter pull-down. | Higher BOM count and layout complexity; no built-in VI(on)/VI(off) hysteresis or ESD protection. | Select when legacy designs require pin-compatible upgrade with full control over bias network values. |
| NHDTC124EU | Same SOT323 package but with R1 = R2 = 22 kΩ; higher VI(on) = 2.3–3.0 V and lower hFE = 70 min. | Better noise immunity in noisy environments; reduced base current draw suits battery-powered systems. | Select when driving 3.3 V logic with tighter VI(off) margin or extending battery life in always-on sensor nodes. |
Compared with BC846B,115, NHDTC114EUF reduces component count and layout area; compared with NHDTC124EU, it offers lower VI(on) and higher hFE, making it preferable for 5 V logic interfaces requiring faster switching and stronger drive.

FAQ
What is the maximum operating temperature for NHDTC114EUF?
The NHDTC114EUF has a maximum junction temperature (Tj) of 150 °C and operates across an ambient temperature range of -55 °C to +150 °C. Thermal resistance from junction to ambient is 532 K/W on single-layer FR4 PCB, requiring derating above 75 °C ambient per Figure 1's power curve.
Does NHDTC114EUF require an external base resistor?
No. NHDTC114EUF integrates R1 = 10 kΩ (base-to-input) and R2 = 10 kΩ (base-to-emitter) internally, enabling direct connection to 3.3 V or 5 V logic outputs without external bias components. This is confirmed in Table 3 (Pinning) and Section 11 (Test Information).
How does NHDTC114EUF differ from NHDTC114EU?
NHDTC114EUF uses the same die and electrical specifications as NHDTC114EU but is supplied in tape-and-reel packaging optimized for automated SMT placement (EIA-481 compliant). The 'F' suffix denotes full reel packaging; all electrical, thermal, and reliability characteristics remain identical.
Can NHDTC114EUF replace BC846B in existing designs?
Yes - with minor layout revision. NHDTC114EUF uses the same SOT323 footprint and pinout (1=base, 2=emitter, 3=collector) as BC846B, but replaces the discrete transistor + two resistors with a single device. No changes to net connectivity are needed beyond removing the external resistors.
