Product details
Overview
PN2907A_J05Z from ON Semiconductor is a 60 V PNP bipolar junction transistor (BJT) designed for general-purpose amplification and switching in low-to-medium power circuits, with DC current gain (hFE) of 100–300 at IC = −150 mA, VCE = −10 V, collector current capability up to −800 mA, and turn-off time of 100 ns - used in discrete logic-level switching and analog signal conditioning stages.
For engineers reviewing the PN2907A_J05Z datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (TO-92, J61Z lead form), absolute maximum ratings, switching timing data, saturation voltage behavior, and real-world substitution guidance aligned with Fairchild/ON Semiconductor's official documentation.
Technical Context
This PNP BJT operates with a maximum collector-emitter breakdown voltage of −60 V and emitter-base breakdown voltage of −5.0 V, supporting robust operation in negative-rail bias configurations. Its thermal resistance (RθJA) is 200 °C/W on standard FR-4 PCB, enabling stable performance up to +150 °C junction temperature.
The device exhibits a minimum current gain–bandwidth product (fT) of 200 MHz at IC = −50 mA, VCE = −20 V, f = 100 MHz, and delivers fast switching with ton ≤ 45 ns and toff ≤ 100 ns under specified drive conditions - making it suitable for pulse-width modulation and digital logic interfacing where speed and gain consistency matter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V: Maximum safe collector-emitter voltage before avalanche breakdown; defines rail compatibility in negative-supply switching stages. |
| IC (Continuous) | −800 mA: Continuous collector current rating; supports load switching up to ~0.8 A without forced cooling. |
| hFE @ IC = −150 mA | 100–300: DC current gain range at mid-current; enables predictable base drive sizing for saturated switch design. |
| VCE(sat) @ IC = −150 mA | −0.4 V max: Low saturation voltage ensures minimal conduction loss and heat generation in on-state operation. |
| toff | 100 ns max: Turn-off delay critical for high-frequency switching applications such as LED dimming or relay drivers. |
| RθJA | 200 °C/W: Junction-to-ambient thermal resistance on standard PCB; informs heatsinking requirements for sustained power dissipation. |
| fT | 200 MHz min: Gain-bandwidth product confirming usable frequency response beyond audio and low-speed digital domains. |
Pinout & Package
PN2907A_J05Z uses the TO-92 package with J61Z lead form (molded, 0.200″ inline spacing), featuring three leads in Emitter–Base–Collector (EBC) order when viewed with flat side facing user and leads downward. This configuration matches JEDEC TO-92 mechanical standards and supports through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E (Emitter) | Current source terminal for PNP operation | Connected to higher potential rail; base-emitter forward bias initiates conduction from emitter to collector. |
| B (Base) | Control input for minority-carrier injection | Receives negative-going drive signal relative to emitter to turn device on; requires current-limited sourcing. |
| C (Collector) | Current sink terminal | Typically tied to load and ground return path; carries full switched current when saturated. |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain range | hFE = 100–300 at IC = −150 mA ensures consistent base drive across production lots and temperature ranges. |
| Fast switching performance | ton ≤ 45 ns and toff ≤ 100 ns enable reliable operation in PWM frequencies up to ~2 MHz with margin. |
| Low VCE(sat) | −0.4 V max at IC = −150 mA reduces power loss and self-heating during continuous conduction. |
| Robust voltage ratings | VCEO = −60 V and VCBO = −60 V support use in 48 V industrial control rails and automotive battery-sensed circuits. |
| Thermal stability | Junction temperature range of −55 °C to +150 °C allows deployment in extended-temperature environments like motor drives and outdoor electronics. |
Applications
| LED Driver Circuit | Relay Interface Stage |
|---|---|
Use Scenario: Driving high-brightness LEDs from microcontroller GPIO pins with current limiting via emitter resistor. IC Role / Device Role / Timing Role: PNP switch controlling LED anode connection to positive supply; base driven low by MCU output. Use Value: Low VCE(sat) minimizes voltage drop across transistor, preserving forward voltage margin for LED string; hFE ≥ 100 ensures sufficient gain for direct GPIO drive without external buffer. |
Use Scenario: Isolating and amplifying logic-level signals to energize 12 V or 24 V electromagnetic relays in PLC I/O modules. IC Role / Device Role / Timing Role: General-purpose PNP switch sinking relay coil current to ground when base is pulled low. Use Value: −800 mA IC rating accommodates typical relay coils (≤ 500 mA), while 100 ns toff prevents contact chatter during rapid on/off cycling. |
| Analog Signal Inverter | Discrete Logic Level Shifter |
Use Scenario: Inverting small-signal AC audio or sensor outputs in single-supply amplifier stages where NPN biasing is impractical. IC Role / Device Role / Timing Role: Common-emitter amplifier with emitter grounded and collector load resistor tied to positive rail. Use Value: hFE bandwidth product ≥ 200 MHz ensures flat frequency response into audio band (20 Hz–20 kHz); low Cob (8 pF) preserves high-frequency fidelity. |
Use Scenario: Translating 3.3 V logic outputs to −5 V or −12 V levels for legacy industrial bus interfaces (e.g., RS-232 driver input stages). IC Role / Device Role / Timing Role: PNP-based level translator with base referenced to input logic and emitter tied to negative supply rail. Use Value: VEB breakdown of −5.0 V permits safe operation with 3.3 V inputs; fast switching supports baud rates up to 1 Mbps without distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT2907A | SOT-23 surface-mount package; lower PD (350 mW) and higher RθJA (357 °C/W); same electrical specs otherwise. | Preferred for space-constrained PCBs; unsuitable for >350 mW continuous dissipation without thermal relief. | Select MMBT2907A only when board area is limited and thermal management allows SMT mounting. |
| PZT2907A | SOT-223 package with 4-pin layout (collector tab); higher PD (1000 mW); RθJA = 125 °C/W; identical electrical characteristics. | Used in higher-power switching where >500 mW dissipation occurs; requires larger land pattern and thermal pad. | Choose PZT2907A when operating near −500 mA continuously or when improved thermal performance is required. |
Compared with PN2907A_J05Z, MMBT2907A trades through-hole reliability and thermal headroom for compactness, while PZT2907A provides superior power handling and thermal efficiency - both retain identical gain, voltage, and timing specs but differ fundamentally in mechanical implementation and thermal limits.

FAQ
What is the pin configuration of PN2907A_J05Z?
PN2907A_J05Z uses the TO-92 package with J61Z lead form and EBC (Emitter–Base–Collector) pinout when viewed with the flat side facing the user and leads pointing downward. Pin 1 is Emitter, Pin 2 is Base, and Pin 3 is Collector - matching JEDEC TO-92 mechanical standard and confirmed in Fairchild's official package drawings (ZA03F).
Does PN2907A_J05Z support switching at 1 MHz?
Yes, PN2907A_J05Z supports switching at 1 MHz in practical designs due to its guaranteed fT ≥ 200 MHz and measured toff ≤ 100 ns. However, actual achievable frequency depends on external circuit parasitics, base drive strength, and load conditions - validated operation at 1 MHz requires proper base resistor selection and layout optimization.
What is the maximum power dissipation of PN2907A_J05Z?
PN2907A_J05Z has a maximum total device dissipation (PD) of 625 mW at TA = 25 °C, derating linearly by 5.0 mW/°C above that temperature. This rating assumes mounting on a standard FR-4 PCB per Fairchild's thermal test condition (1.6″ × 1.6″ × 0.06″), and must be adjusted for actual board layout and airflow.
Can PN2907A_J05Z replace PN2907 in existing designs?
Yes, PN2907A_J05Z is a direct revision upgrade of the original PN2907, offering tighter hFE distribution (100–300 vs. older 100–250), improved fT (≥200 MHz vs. unspecified), and updated process control. Electrical and mechanical compatibility is maintained, and no PCB changes are required for drop-in replacement in legacy TO-92 layouts.
Is PN2907A_J05Z RoHS compliant?
Yes, PN2907A_J05Z is RoHS compliant and meets lead-free soldering requirements per ON Semiconductor's product change notices and material declarations. It conforms to EU Directive 2011/65/EU and subsequent amendments, with homogeneous lead content below 1000 ppm.
