Product details
Overview
MPSA06_D75Z from ON Semiconductor is an NPN general-purpose amplifier transistor rated for 80 V VCEO, 500 mA continuous collector current, and 625 mW power dissipation in TO-92 package - used in low-to-medium-power linear amplification and switching stages of industrial control interfaces, sensor signal conditioning circuits, and relay drivers.
For engineers reviewing the MPSA06_D75Z datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal behavior, package mapping, and real-world use context - all confirmed against Fairchild/ON Semiconductor official documentation for design validation and BOM selection.
Technical Context
The MPSA06_D75Z operates as a silicon NPN bipolar junction transistor with DC current gain (hFE) ≥100 at both IC = 10 mA and IC = 100 mA, VCE = 1.0 V. Its fT of 100 MHz supports audio-frequency amplification and moderate-speed switching up to ~10–20 MHz with proper biasing.
It features low VCE(sat) of 0.25 V at IC = 100 mA / IB = 10 mA and VBE(on) of 1.2 V under same conditions - enabling efficient operation in saturated-switching configurations without excessive base drive overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage before breakdown; suitable for 24–48 V industrial bus interfacing. |
| IC (continuous) | 500 mA - Sustained collector current handling; supports relay coils up to ~300 mA and small solenoids. |
| PD (TO-92) | 625 mW - Total device dissipation at 25°C ambient; derates 5.0 mW/°C above TA = 25°C. |
| hFE | ≥100 - Minimum DC current gain at two operating points; ensures stable biasing across production lots. |
| fT | 100 MHz - Gain-bandwidth product at IC = 10 mA, VCE = 2.0 V; enables audio preamp and low-speed digital signal buffering. |
| VCE(sat) | 0.25 V - Low saturation voltage reduces conduction loss in switching applications like LED drivers or logic-level translators. |
Pinout & Package
Package: TO-92 (3-lead molded plastic), standard straight-lead configuration per JEDEC TO-92. Pin identification verified via official Fairchild physical dimensions diagram (Fig. 11) and marking orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E (Emitter) | Current sink terminal | Reference node for bias network; connects to ground or low-impedance return path in common-emitter amplifier. |
| B (Base) | Control input | Receives forward-biased current to modulate collector current; requires series resistor to limit IB and prevent thermal runaway. |
| C (Collector) | Current source terminal | Drives load (e.g., relay coil, LED string); must be connected through load to positive supply in switching mode. |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | 80 V withstand capability allows direct interface with 48 V industrial control rails without external clamping. |
| Stable hFE over current range | Minimum hFE ≥100 at both 10 mA and 100 mA ensures predictable gain in multi-stage amplifiers and consistent switching thresholds. |
| Low VCE(sat) | 0.25 V saturation voltage minimizes power loss and self-heating when used as a saturated switch in 5–24 V logic-driven loads. |
| TO-92 mechanical compatibility | Standard through-hole footprint enables drop-in replacement in legacy designs using MPSA05, MPSA13, or similar NPN transistors. |
Applications
| Industrial Relay Driver | Audio Pre-amplifier Stage |
|---|---|
|
Use Scenario: Driving 24 VDC industrial relays with coil currents up to 200 mA in PLC I/O modules. IC Role / Device Role / Timing Role: NPN switching transistor configured in common-emitter mode with base resistor network and flyback diode protection. Use Value: 80 V VCEO safely absorbs inductive kickback; 0.25 V VCE(sat) limits power dissipation to <100 mW during on-state. |
Use Scenario: First-stage small-signal amplification in analog sensor signal chains (e.g., thermocouple or RTD front-end). IC Role / Device Role / Timing Role: Linear amplifier biased in active region with emitter degeneration for gain stability and distortion control. Use Value: hFE ≥100 at 10 mA ensures >20 dB voltage gain with minimal bias drift; fT = 100 MHz preserves bandwidth up to 20 kHz. |
| LED Current Switch | Logic-Level Translator |
|
Use Scenario: Controlling high-brightness indicator LEDs or small LED arrays in embedded HMI panels. IC Role / Device Role / Timing Role: Saturated switch connecting LED anode to supply rail while sinking cathode current to microcontroller GPIO. Use Value: 500 mA IC rating supports parallel LED strings; low VCE(sat) maintains LED forward voltage accuracy and thermal margin. |
Use Scenario: Level-shifting 3.3 V MCU outputs to drive 5 V or 12 V peripheral enable lines in mixed-voltage systems. IC Role / Device Role / Timing Role: Inverting translator with pull-up resistor on collector and base driven by GPIO. Use Value: Fast turn-on/off due to fT = 100 MHz enables clean edge transitions; VBE(on) = 1.2 V ensures reliable turn-on from 3.3 V logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSA13 | Higher hFE (50–250 vs. 100 min), same VCEO/IC, TO-92 package | Better suited for low-base-drive applications; less stable gain across temperature and current range | Select MPSA13 only if high DC gain is required and gain variation is acceptable; MPSA06_D75Z preferred for consistent biasing. |
| BC547B | Lower VCEO (45 V), same TO-92, hFE 200–450 (min 110), lower PD (500 mW) | Limited to ≤36 V systems; higher gain but reduced voltage safety margin and thermal headroom | Choose BC547B only in low-voltage consumer designs; MPSA06_D75Z provides superior voltage robustness and power handling. |
Compared with MPSA13 and BC547B, the MPSA06_D75Z offers balanced trade-offs: guaranteed minimum hFE, industry-grade 80 V rating, and 625 mW dissipation - making it optimal for industrial control where reliability across voltage, temperature, and production variance is critical.

FAQ
What is the maximum collector-emitter voltage rating for MPSA06_D75Z?
The MPSA06_D75Z has a VCEO rating of 80 V, verified in the official Fairchild/ON Semiconductor datasheet under Absolute Maximum Ratings. This value defines the maximum voltage the device can withstand between collector and emitter with base open, and is critical for ensuring safe operation in 24 V and 48 V industrial systems. Exceeding 80 V risks irreversible breakdown. The MPSA06_D75Z must not be used in circuits where transient or steady-state VCE exceeds this limit without external clamping.
Is MPSA06_D75Z pin-compatible with other TO-92 NPN transistors like MPSA05 or MPSA13?
Yes - the MPSA06_D75Z uses standard TO-92 pinout (E-B-C, viewed from flat side with leads down), matching MPSA05, MPSA13, and BC547 series. However, electrical differences exist: MPSA05 has lower VCEO (60 V), while MPSA13 has higher hFE but wider gain spread. The MPSA06_D75Z is not a drop-in functional replacement without verifying bias network compatibility, especially in gain- or voltage-critical designs.
What is the typical DC current gain (hFE) of MPSA06_D75Z and at what conditions is it specified?
The MPSA06_D75Z guarantees hFE ≥100 at two test conditions: IC = 10 mA, VCE = 1.0 V and IC = 100 mA, VCE = 1.0 V. This dual-point specification ensures usable gain across both small-signal and medium-current operation. Actual hFE may exceed 200 in production units, but design margins must rely on the minimum 100 value. The MPSA06_D75Z maintains this minimum across its full operating temperature range (−55°C to +150°C).
Can MPSA06_D75Z be used in switching applications, and what is its saturation voltage?
Yes - the MPSA06_D75Z is widely used in saturated switching applications. Its VCE(sat) is specified at 0.25 V maximum when IC = 100 mA and IB = 10 mA, confirming strong saturation with β = 10. This low saturation voltage reduces conduction loss and self-heating, making the MPSA06_D75Z suitable for driving relays, LEDs, and small solenoids. For reliable switching, ensure base current meets or exceeds 10% of target collector current.
What is the power dissipation capability of MPSA06_D75Z and how does it change with temperature?
The MPSA06_D75Z has a total device dissipation (PD) of 625 mW at TA = 25°C in TO-92 package, with a thermal derating factor of 5.0 mW/°C above 25°C. At 75°C ambient, usable power drops to 375 mW. This derating must be applied in enclosed or high-temperature environments. The MPSA06_D75Z's RθJA of 200°C/W reflects standard FR-4 PCB mounting - heatsinking or airflow improves thermal performance but does not alter the datasheet's defined derating slope.
