Product details
Overview
NHDTC123JTR from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 package, designed for digital switching applications with 80 V VCEO, 100 mA IO, and integrated 2.2 kΩ/47 kΩ bias resistors. It replaces discrete BJT + base resistors in load control, IC input conditioning, and automotive body electronics.
For engineers reviewing the NHDTC123JTR datasheet, NHDTC123JTR pinout, NHDTC123JTR application, or NHDTC123JTR equivalent, this part delivers verified 80 V breakdown, 100 mA output capability, and simplified PCB layout via built-in R1/R2 network - critical for space-constrained digital interface and low-side switching designs.
Technical Context
This RET integrates a high-voltage NPN transistor with two precision on-die resistors: R1 (2.2 kΩ) connects base to input, and R2 (47 kΩ) pulls base to emitter. The configuration enables direct logic-level drive without external bias components.
It operates with VI(on) = 0.81–1.2 V at IC = 10 mA and VCE = 0.3 V, and maintains VI(off) ≤ 500 mV up to 595 mV typical, ensuring reliable turn-off under noise margin constraints in automotive and industrial digital systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Supports operation in 24 V automotive and 48 V industrial bus systems with safety margin. |
| IO | 100 mA - Drives LED arrays, small relays, or logic inputs without external current amplification. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Enables direct 3.3 V/5 V microcontroller GPIO drive with defined base current and fast turn-off. |
| VCE(sat) | ≤100 mV at IC = 10 mA, IB = 0.5 mA - Minimizes conduction loss in low-power switching nodes. |
| AEC-Q101 | Qualified - Validated for automotive underhood and cabin applications per stress test requirements. |
| Ptot | 250 mW (FR4 single-layer) - Compatible with standard SMT assembly and thermal relief design rules. |
| hFE | 100 min at VCE = 5 V, IC = 10 mA - Ensures predictable gain for saturated switch operation. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package: 3-pin, 1.3 mm × 2.9 mm footprint, 1.1 mm height, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Logic-level signal entry point; internally connected to R1 top node and transistor base. |
| 2 | GND (emitter) | Emitter reference and return path; tied to R2 bottom node and system ground plane. |
| 3 | Output (collector) | Switched load connection; carries full output current with minimal saturation voltage. |
Key Features

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; requires external 10 kΩ base resistor for 5 V drive; no integrated R2 pull-down. | Lacks guaranteed turn-off behavior under floating input conditions; higher risk of unintended conduction in noisy environments. | Select when cost-per-transistor is prioritized and board space allows discrete bias network. |
| NHDTC143ZTR | R1 = 4.7 kΩ (vs. 2.2 kΩ); same R2 = 47 kΩ; higher VI(on) threshold (0.95–1.4 V). | Better suited for 5 V logic interfaces where higher input threshold improves noise rejection. | Choose for 5 V MCU systems requiring tighter input voltage margin control and reduced standby current. |
Compared with BC846B,115, NHDTC123JTR reduces bill-of-materials and improves noise immunity via integrated R2; versus NHDTC143ZTR, it offers lower VI(on) for reliable 3.3 V drive but slightly higher input current draw.

FAQ
What is the maximum safe operating voltage for NHDTC123JTR?
The absolute maximum collector-emitter voltage (VCEO) is 80 V with open base, verified per IEC 60134 limiting values. Operation above 60 V is permitted only with appropriate transient suppression and derating per ambient temperature - e.g., 70 V max at 85 °C ambient per Fig. 1 power derating curve.
Can NHDTC123JTR be used with 3.3 V microcontrollers?
Yes. Its typical VI(on) is 0.81 V at IC = 10 mA and VCE = 0.3 V, well within 3.3 V logic high range. With R1 = 2.2 kΩ, a 3.3 V GPIO delivers ~1.1 mA base current - sufficient for full saturation at 100 mA IC (hFE ≥ 100).
How does the built-in R2 resistor improve system reliability?
R2 = 47 kΩ provides active base-to-emitter pull-down, ensuring the transistor remains fully off when the input is floating or high-impedance. This eliminates false triggering from EMI or leakage currents - critical in automotive CAN node interfaces and industrial field wiring where unterminated lines are common.
Is thermal performance affected by PCB copper layer count?
Yes. Total power dissipation is 250 mW on single-sided FR4 and 350 mW on 4-layer FR4 (per Table 6). Thermal resistance Rth(j-a) drops from 500 K/W to 358 K/W with increased copper mass, enabling higher sustained current in thermally dense layouts - verify layout against Fig. 1 derating curves.
