Product details
Overview
NHDTA114ETR from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 package, designed for digital switching and IC input control. It features 80 V collector-emitter breakdown voltage, 100 mA output current capability, built-in 10 kΩ base resistors (R1 = R2), and AEC-Q101 qualification for automotive-grade reliability. Used in load switching and logic-level interfacing where component count reduction is critical.
For engineers reviewing the NHDTA114ETR datasheet, NHDTA114ETR pinout, NHDTA114ETR application, or NHDTA114ETR equivalent, this page provides verified pin functions, thermal derating curves, on/off-state input voltage thresholds, saturation voltage at 10 mA, and direct alternatives to BC856-series discrete transistors in cost-sensitive digital circuits.
Technical Context
This device integrates a PNP bipolar transistor with two monolithic silicon resistors (R1 = R2 = 10 kΩ) to form a single-input, single-output digital switch. Its internal structure eliminates external biasing components and enables direct connection to CMOS/TTL outputs without level-shifting.
The RET operates with guaranteed VCE(sat) ≤ −100 mV at IC = −10 mA / IB = −0.5 mA and supports off-state input voltage (VI(off)) down to −1.15 V, ensuring robust noise immunity in industrial control interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Withstands 80 V reverse collector-emitter voltage before breakdown, enabling use in 24 V and 48 V industrial bus switching. |
| IO | −100 mA - Delivers up to 100 mA continuous collector current, sufficient for driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 10 kΩ / 10 kΩ - Integrated base resistors eliminate need for external bias network, reducing BOM count by two passive components. |
| VCE(sat) | ≤ −100 mV @ IC = −10 mA - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| VI(on) | −2.5 V to −1.8 V @ VCE = −0.3 V - Confirmed turn-on threshold compatible with standard 3.3 V and 5 V logic families. |
| hFE | 50 min @ VCE = −5 V, IC = −10 mA - Guaranteed DC current gain ensures reliable switching margin across temperature range. |
| AEC-Q101 | Qualified - Meets automotive stress test requirements for temperature cycling, HTRB, and ESD, supporting under-hood and infotainment applications. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package: 3-pin, 1.3 mm × 2.9 mm footprint, 1.1 mm height, JEDEC-compliant lead pitch of 0.95 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Internal connection to R1 and R2 network; accepts logic-level drive directly from MCU GPIO or buffer output. |
| 2 | GND (emitter) | Emitter tied to system ground; serves as common reference for input and output paths in low-side switching configuration. |
| 3 | Output (collector) | Switched high-side output node; connects to load anode or pull-up rail when active, sinking current to pin 2. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Monolithic 10 kΩ R1/R2 eliminates external components and PCB routing for base bias, cutting assembly time and failure points. |
| Low VCE(sat) | ≤ −100 mV at rated current reduces conduction loss to < 1 mW, enabling compact thermal design in space-constrained modules. |
| High VCEO | −80 V rating supports operation across 12 V–48 V supply domains without additional protection circuitry. |
| AEC-Q101 qualification | Validated for automotive environments including −40 °C to +125 °C ambient operation and 1000-cycle temperature cycling. |
| Small SOT23 footprint | 0.95 mm lead pitch and 2.9 mm × 1.3 mm body enable high-density placement on 4-layer PCBs with minimal layout impact. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NHDTC114ET | NPN complement with identical R1/R2 values (10 kΩ), same SOT23 package and AEC-Q101 rating. | Requires inverted logic drive and high-side load configuration instead of low-side; not drop-in compatible. | Select when sourcing NPN logic interface or designing complementary push-pull stages. |
| BC856B,215 | Discrete PNP transistor without integrated resistors; requires external 10 kΩ base resistor and higher board area. | Offers higher hFE (160–400) but increases component count, layout complexity, and assembly cost. | Choose only if precise gain tuning or higher frequency operation (>100 MHz) is required beyond RET capability. |
Compared with NHDTC114ET, NHDTA114ETR provides native low-side switching with non-inverted control; versus BC856B, it delivers identical electrical performance while reducing PCB real estate by 35% and eliminating two solder joints per channel.

FAQ
What is the maximum allowable junction temperature for NHDTA114ETR?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the limiting values table. Operation above this temperature risks permanent degradation of the silicon die and integrated resistors. Derating is required above 25 °C ambient per Figure 1, with total power dissipation dropping to 250 mW at 75 °C ambient on single-sided FR4 PCB.
Can NHDTA114ETR be used in high-frequency switching applications?
No - its transition frequency (fT) is 150 MHz under specified conditions, but the integrated resistors limit effective switching speed. It is optimized for DC and low-frequency digital switching (≤ 100 kHz), not RF or PWM dimming. For >1 MHz operation, discrete transistors without built-in resistors are recommended.
How does the built-in resistor ratio affect switching behavior?
The R2/R1 ratio is fixed at 1.0 for NHDTA114ETR, meaning both resistors are 10 kΩ. This symmetric configuration ensures stable biasing and consistent VI(on)/VI(off) thresholds across temperature, eliminating variability from mismatched external resistors and improving batch-to-batch consistency in production.
Is NHDTA114ETR pin-compatible with standard SOT23 PNP transistors like BC856?
Yes - it uses the same SOT23 (TO-236AB) mechanical outline and pin assignment (pin 1 = base, pin 2 = emitter, pin 3 = collector). However, internal resistor integration means external base resistors must be omitted from the schematic to avoid double-biasing and potential latch-up or excessive current draw.
