Product details

Overview

2DD1766P-13 from Diodes Incorporated is an AEC-Q101 qualified NPN bipolar junction transistor in SOT89-3L package, rated for 32 V V_CEO, 2 A continuous collector current, and 1 W power dissipation at T_A = 25°C. It delivers h_FE of 82–180 at I_C = 0.5 A, V_CE = 3 V, and f_T = 220 MHz, supporting medium-power switching and linear amplification in automotive power control modules.

For engineers reviewing the 2DD1766P-13 datasheet, 2DD1766P-13 pinout, 2DD1766P-13 application, or 2DD1766P-13 equivalent, key selection criteria include V_CEO/I_C derating at elevated ambient temperature, SOT89-3L thermal pad layout compliance, h_FE binning (P/Q/R), and AEC-Q101 qualification status for automotive-grade reliability validation.

Technical Context

This NPN transistor uses epitaxial planar die construction for stable gain and low saturation voltage. Its 0.3–0.8 V V_CE(SAT) at I_C = 2 A / I_B = 0.2 A enables efficient medium-power switching, while 220 MHz f_T supports high-frequency amplification up to UHF band edge.

Designed for IATF 16949-certified manufacturing, it features matte tin-plated copper leadframe, J-STD-020 Level 1 moisture sensitivity, and UL 94V-0 molded plastic housing - all aligned with automotive PPAP requirements and "Green" halogen/antimony-free compliance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	32 V - Maximum safe collector-emitter voltage before avalanche breakdown under DC conditions
I_C (continuous)	2 A - Continuous collector current rating at T_A = 25°C with proper PCB thermal relief
P_D	1 W - Power dissipation limit on FR-4 board with Diodes' recommended SOT89-3L pad layout
h_FE (2DD1766P)	82–180 - DC current gain range at V_CE = 3 V, I_C = 0.5 A, defining base drive sizing margin
f_T	220 MHz - Transition frequency indicating usable small-signal amplification bandwidth
V_CE(SAT)	0.3–0.8 V - Saturation voltage at I_C = 2 A / I_B = 0.2 A, directly determining conduction loss in switch mode
R_θJA	125 °C/W - Junction-to-ambient thermal resistance, used to calculate max operating ambient for given P_D

Pinout & Package

Package: SOT89-3L - surface-mount, thermally enhanced 3-pin plastic package with exposed collector tab for PCB heat sinking. Dimensions: 4.5 × 2.5 × 1.05 mm (L × W × H), weight ≈ 0.072 g.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	E	Current sink node; connected to ground or low-side return path in switching circuits
2 & 4 (Collector)	C	Electrically tied pins forming main power output node; soldered to large copper pour for thermal management
3 (Base)	B	Control input requiring current-limited drive; typical I_B = 0.2 A for full saturation at I_C = 2 A

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN medium-power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
FCX491TA	V_CEO = 40 V, I_C = 1 A, h_FE = 100–300, SOT89-3L	Higher voltage rating but lower current capability; not AEC-Q101 qualified	Select when V_CEO margin > 32 V is required and automotive qualification is not mandatory
FCX491ATA	V_CEO = 40 V, I_C = 1 A, h_FE = 180–390, SOT89-3L, AEC-Q101 qualified	Same qualification level but reduced I_C rating; tighter h_FE binning	Preferred replacement where AEC-Q101 compliance must be retained and peak load current ≤1 A

Compared with 2DD1766P-13, FCX491TA trades automotive qualification for higher V_CEO, while FCX491ATA maintains AEC-Q101 compliance but reduces I_C by 50%, requiring redesign of base drive and thermal layout for equivalent power handling.

FAQ

Is 2DD1766P-13 still in active production?

No - Diodes Incorporated has officially discontinued the 2DD1766P/Q/R family as of March 2024. The datasheet states "OBSOLETE – PART DISCONTINUED" and recommends FCX491TA or FCX491ATA as replacements. Aetrix Electronics holds final-shipment inventory with full traceability and documentation.

What is the difference between 2DD1766P, Q, and R variants?

The suffix denotes h_FE binning: 2DD1766P = 82–180, Q = 120–270, R = 180–390, all measured at V_CE = 3 V, I_C = 0.5 A. All share identical maximum ratings, package, and qualification status. Marking code is N23P/N23Q/N23R on top of SOT89-3L body.

Can 2DD1766P-13 be used in non-automotive applications?

Yes - its electrical and thermal specifications apply universally. However, AEC-Q101 qualification adds value only in automotive contexts; for industrial or consumer use, the same performance is achieved without qualification overhead. Thermal derating and PCB layout rules remain unchanged regardless of end application.

What is the recommended PCB pad layout for thermal performance?

Diodes specifies a minimum 10 mm² copper pour connected to Pin 2 & 4 (collector) on the top layer, with ≥4 thermal vias (0.3 mm diameter) to inner ground/power planes. Full layout guidelines are published in Diodes' SOT89-3L packaging document (ref: https://www.diodes.com/design/support/packaging/diodes-packaging/).
