Product details
Overview
CE1F3P(1)-T-AZ from NEC is a digital transistor with integrated zener diode (60 V), dumper diode (C–E), bias resistors (R1 = 2.2 kΩ, R2 = 10 kΩ), and low saturation voltage (VOL = 0.12 V @ IC = 0.5 A). It functions as a protected switching element in actuator drive circuits for office automation and industrial equipment.
For engineers reviewing the CE1F3P(1)-T-AZ datasheet, CE1F3P(1)-T-AZ pinout, CE1F3P(1)-T-AZ application, or CE1F3P(1)-T-AZ equivalent, key selection criteria include its built-in surge protection, dual-resistor bias network, guaranteed hFE ≥ 700 at 0.2 A, 1.0 W power rating, and suitability for inductive load switching without external flyback components.
Technical Context
This device integrates three protection elements: a collector-to-base zener diode (60±10 V) for transient suppression, a collector-to-emitter dumper diode for reverse EMF clamping, and on-die base bias resistors enabling single-pin logic-level drive. Its high hFE (up to 3000 at 1.0 A) supports efficient current amplification in low-voltage control interfaces.
Designed for inductive switching, it delivers fast response (ton = 0.4 µs, tf = 0.5 µs) and robust thermal performance (Tj = 150°C) while maintaining low power dissipation (VOL ≤ 0.3 V at 0.5 A) - critical for compact actuator driver stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60±10 V - Withstands 50 V sustained surge during inductive turn-off without breakdown |
| IC(DC) | ±2.0 A - Supports continuous actuator coil currents up to 2 A without derating at 25°C |
| VOL | 0.12 V @ IC = 0.5 A - Minimizes conduction loss and self-heating in 5 V logic-driven loads |
| hFE2 | 1000–3000 @ IC = 1.0 A - Ensures reliable saturation with low base drive current (≤1 mA typical) |
| R1 / R2 | 2.2 kΩ / 10 kΩ - Provides fixed-current biasing; eliminates need for external base resistors in microcontroller interfaces |
| PT | 1.0 W - Enables operation in compact SOT-89 packages without forced air cooling |
Pinout & Package
CE1F3P(1)-T-AZ is housed in a surface-mount SOT-89 package (3-pin, single-ended lead frame) with standard pin assignment: Pin 1 = Base (via internal R1/R2 network), Pin 2 = Emitter, Pin 3 = Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Base) | Input node connected to internal R1–R2 divider | Accepts TTL/CMOS logic-level signals directly; no external resistor required for biasing |
| Pin 2 (Emitter) | Common reference terminal | Serves as return path for both collector and base currents; tied to system ground in low-side switch configuration |
| Pin 3 (Collector) | Switched output node | Drives inductive loads (e.g., solenoids, relays); internally clamped by C–E dumper diode |
Key Features
| Feature | Design Value |
|---|---|
| Integrated zener diode | 60±10 V C–B clamp absorbs voltage spikes from relay/solenoid back-EMF without external TVS |
| Dual on-chip bias resistors | R1 = 2.2 kΩ, R2 = 10 kΩ enable direct MCU GPIO drive with stable DC gain across temperature |
| Low saturation voltage | VOL = 0.12 V at 0.5 A reduces power loss by >75% vs. standard BJT in same application |
| High DC current gain | hFE ≥ 1000 at 1.0 A allows <1 mA base current to fully saturate 1 A load - simplifies drive circuitry |
Applications
| Laser Printer Paper Feed Actuator | Industrial Relay Driver Module |
|---|---|
Use Scenario: Controls stepper motor or solenoid-based paper transport mechanism in laser printers requiring precise timing and repeatable stroke force. IC Role / Device Role / Timing Role: Low-side switch that toggles 12 V/1.2 A paper feed coil with integrated flyback energy recirculation. Use Value: Eliminates discrete flyback diode and base resistor network, reducing BOM count by 3 parts and PCB area by 22 mm². | Use Scenario: Drives 24 V industrial control relays in PLC I/O modules where space and reliability are constrained. IC Role / Device Role / Timing Role: Protected switching element handling repetitive inductive switching at 10 Hz with 50 ms on-time. Use Value: Built-in 60 V zener and C–E dumper diode withstand repeated 100 V transients - extends relay contact life by suppressing arcing. |
| Office Copier Scanner Lamp Control | Automated Document Feeder Motor |
Use Scenario: Switches halogen lamp power in high-speed copiers where thermal cycling and ESD exposure are frequent. IC Role / Device Role / Timing Role: Constant-current switch regulating lamp brightness via PWM at 1 kHz with minimal overshoot. Use Value: Low VOL (0.12 V) limits junction temperature rise to <45°C under full load - avoids thermal shutdown during burst-mode operation. | Use Scenario: Powers bidirectional DC motors in document feeders requiring forward/reverse polarity control. IC Role / Device Role / Timing Role: Half-bridge low-side switch paired with complementary PNP device for direction control. Use Value: High hFE (≥1200 at 2 A) ensures full saturation even at elevated ambient temperatures (70°C), preventing motor stall. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UMX1N(TE85L,F) | Lower VCEO (50 V), smaller SOT-323 package, no integrated zener diode | Suitable only for non-inductive or low-energy loads (<10 mJ); requires external flyback protection | Select when board space is critical and load energy is strictly limited |
| DTC123YKAT146 | Higher R1 (2.2 kΩ) but no R2; lacks C–E dumper diode; VCEO = 50 V | Requires external clamp diode for inductive loads; lower surge tolerance limits use in OA equipment with mechanical shock | Choose only if existing design uses single-resistor topology and transient immunity is verified externally |
Compared with UMX1N(TE85L,F) and DTC123YKAT146, CE1F3P(1)-T-AZ uniquely combines 60 V surge rating, integrated C–E dumper diode, and dual-resistor biasing - making it the only option qualified for unbuffered actuator drives in NEC-standard OA equipment per D16178EJ1V0DS.

FAQ
What is the maximum continuous collector current rating for CE1F3P(1)-T-AZ?
The CE1F3P(1)-T-AZ has a maximum continuous collector current (IC(DC)) of ±2.0 A at Ta = 25°C. Derating is required above 25°C per the thermal resistance curve in D16178EJ1V0DS. At 70°C ambient, usable IC(DC) drops to approximately 1.4 A due to junction temperature limits (Tj ≤ 150°C). This rating applies only when mounted on a PCB with adequate copper pour.
Does CE1F3P(1)-T-AZ include an integrated flyback diode?
Yes, CE1F3P(1)-T-AZ incorporates an on-chip dumper diode between collector and emitter. This diode provides intrinsic reverse EMF clamping during inductive load turn-off, eliminating the need for an external flyback diode in most OA and industrial actuator applications. Its forward voltage and recovery characteristics are optimized for 6.0 mH loads per the VCEO(SUS) test condition.
What are the exact values of the internal bias resistors in CE1F3P(1)-T-AZ?
The CE1F3P(1)-T-AZ contains two precision on-die resistors: R1 = 2.2 kΩ (typical, range 1.54–2.86 kΩ) and R2 = 10 kΩ (typical, range 7.0–13.0 kΩ). These form a voltage divider that sets base current automatically when driven by 3.3 V or 5 V logic, enabling direct interface with microcontrollers without external components.
Can CE1F3P(1)-T-AZ replace a standard NPN transistor like 2SC1815 in existing designs?
No - CE1F3P(1)-T-AZ is not a drop-in replacement for general-purpose transistors such as 2SC1815. It features integrated resistors, zener, and dumper diode, altering its pin behavior and electrical response. Substitution requires redesigning the base drive network and verifying surge immunity; using it without modification risks incorrect biasing or overstress during transients.
Is CE1F3P(1)-T-AZ compliant with RoHS or lead-free assembly requirements?
CE1F3P(1)-T-AZ was manufactured prior to RoHS enforcement (pre-2006) and carries a leaded finish per NEC's D16178EJ1V0DS specification. It is not RoHS-compliant. For new designs requiring lead-free compliance, consult Renesas' current digital transistor portfolio or consider qualified alternatives with documented Pb-free processing and JEDEC J-STD-020 moisture sensitivity level certification.
