Product details
Overview
PDTD113ZUF from Nexperia is a 500 mA, 50 V NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, integrating 1 kΩ input bias resistor R1 and 10 kΩ base-emitter resistor R2 with ±10% tolerance. It functions as a digitally controlled switch in low-voltage logic interfaces, delivering 100 mV VCE(sat) at 50 mA/2.5 mA drive and supporting automotive-grade operation up to 175 °C junction temperature.
For engineers reviewing the PDTD113ZUF datasheet, PDTD113ZUF pinout, PDTD113ZUF application, or PDTD113ZUF equivalent, this page provides verified electrical parameters, thermal derating curves, AEC-Q101 qualification status, and direct substitution guidance for digital switching designs requiring simplified BJT biasing.
Technical Context
This RET integrates two precision thin-film resistors (R1 = 1 kΩ, R2 = 10 kΩ) monolithically with an NPN silicon transistor, eliminating external bias components. Its R2/R1 ratio of 10.0 enables stable current gain control and predictable VI(on)/VI(off) thresholds across temperature.
The device operates with VI(on) = 0.4–1.4 V and VI(off) = 0.3–1.0 V at IC = 20–100 µA, making it compatible with 1.8 V, 3.3 V, and 5 V logic families. Built-in ESD protection and AEC-Q101 qualification confirm suitability for automotive body electronics and industrial control I/O stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive supply rails with margin. |
| IO | 500 mA - Continuous output current capability; sufficient for driving relays, LEDs, and small solenoids. |
| R1 / R2 | 1 kΩ / 10 kΩ - Integrated bias network sets fixed base current path; eliminates 2 external resistors in digital switch design. |
| VCE(sat) | 100 mV @ IC = 50 mA, IB = 2.5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| Tj(max) | 175 °C - Junction temperature rating enables operation in under-hood automotive environments without derating. |
| AEC-Q101 | Qualified - Certified for automotive discrete semiconductor stress testing; valid for front-end module, lighting, and HVAC control units. |
| hFE | 70 (typ) @ VCE = 5 V, IC = 50 mA - DC current gain ensures reliable saturation with standard logic-level drive. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.15 mm × 0.45 mm footprint, 3-terminal leadframe with gull-wing leads, optimized for reflow soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level voltage input to control transistor conduction. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common return path for load current. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 = 1 kΩ + R2 = 10 kΩ reduces BOM count by two resistors and PCB area by >2 mm². |
| ±10 % resistor ratio tolerance | Ensures consistent VI(on)/VI(off) thresholds across production lots, critical for deterministic logic-level interfacing. |
| 175 °C junction rating | Enables uninterrupted operation in engine bay, powertrain, and industrial motor control enclosures without thermal shutdown. |
| AEC-Q101 qualification | Validates reliability for automotive applications including door modules, seat controls, and dashboard indicators. |
| Low VCE(sat) | 100 mV at rated current limits power dissipation to ≤50 mW, reducing heatsinking requirements in dense layouts. |

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 |
|---|---|---|---|
| PDTD113EU | R2 = 1 kΩ (R2/R1 = 1.0), lower VI(off) threshold (0.6–1.5 V), hFE = 33 | Better suited for high-speed switching where tighter R2/R1 matching reduces storage time | Select when faster turn-off and lower input leakage are prioritized over noise immunity. |
| BC807-40 | Discrete BJT (no built-in resistors), hFE = 250–630, requires external R1/R2 network | Higher gain but increases component count, layout area, and sensitivity to resistor tolerance drift | Choose only if variable gain tuning or custom bias ratios are required beyond fixed RET configurations. |
Compared with PDTD113EU, PDTD113ZUF offers superior noise immunity due to its 10× R2/R1 ratio and lower VI(off), while BC807-40 demands additional passives and layout effort-making PDTD113ZUF optimal for cost-sensitive, space-constrained digital switching where standardized biasing suffices.

FAQ
What is the maximum continuous collector current for PDTD113ZUF?
The absolute maximum continuous collector current is 500 mA, validated under FR4 PCB conditions with 4-layer copper and standard footprint. Derating is required above 25 °C ambient; at 100 °C, usable current drops to ~350 mA based on thermal resistance (Rth(j-a) = 353 K/W) and 425 mW total power limit.
Does PDTD113ZUF require external bias resistors?
No. PDTD113ZUF integrates R1 = 1 kΩ (base input) and R2 = 10 kΩ (base-emitter) internally, enabling direct connection to logic outputs without external components. This configuration fixes the R2/R1 ratio at 10.0, ensuring predictable VI(on) and VI(off) behavior across temperature and process variation.
Is PDTD113ZUF qualified for automotive use?
Yes. PDTD113ZUF is AEC-Q101 qualified per Stress Test Qualification for Discrete Semiconductors, covering temperature cycling, humidity bias HAST, ESD (HBM ≥2 kV), and high-temperature operating life. It is approved for under-hood and cabin applications including door modules, lighting, and HVAC controls.
How does PDTD113ZUF differ from PDTD113EU?
PDTD113ZUF uses R2 = 10 kΩ (R2/R1 = 10), yielding higher noise immunity and lower VI(off) (0.3–1.0 V), while PDTD113EU uses R2 = 1 kΩ (R2/R1 = 1.0) and has higher VI(off) (0.6–1.5 V) and lower hFE (33 vs. 70). ZUF variant is preferred for noisy 12 V automotive environments; EU suits high-speed, low-storage-time switching.
