Product details
Overview
MSB710-RT1G from onsemi is a PNP general-purpose amplifier transistor in SC-59 (SOT-23) surface-mount package, rated for −50 V V(BR)CEO, −500 mA IC, and 200 mW power dissipation; used in low-voltage switching and linear amplification stages of portable audio preamps and LED driver bias networks.
For engineers reviewing the MSB710-RT1G datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP polarity, guaranteed hFE ≥120 at −150 mA, VCE(sat) ≤ −0.6 V, Pb-free SC-59 footprint compatibility, and −55°C to +150°C operating range.
Technical Context
This discrete PNP bipolar junction transistor operates in active, saturation, and cutoff regions with fixed emitter-base and collector-base junction structures. Its DC current gain spans 120–240 at −150 mA and drops to 40 at −500 mA, indicating gain compression under high-current drive.
Thermal design must account for 200 mW maximum power dissipation at TA = 25°C and derating above that ambient; junction temperature is limited to 150°C, with storage range extending from −55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)CEO | −50 Vdc: Maximum reverse voltage between collector and emitter before breakdown; defines safe operating voltage ceiling in PNP switch configurations. |
| IC Continuous | −500 mAdc: Max continuous collector current; sets upper limit for sustained load switching or analog amplification without thermal runaway. |
| PD | 200 mW: Total package power dissipation at 25°C ambient; requires PCB copper area or airflow if operating near full rating. |
| hFE @ −150 mA | 120–240: DC current gain range at moderate bias; enables predictable base drive calculation for low-power amplification stages. |
| VCE(sat) | ≤ −0.6 Vdc @ −300 mA/−30 mA: Saturation voltage confirms low-loss switching performance in digital logic interface or relay driver circuits. |
| Cob | ≤ 15 pF @ −10 V: Output capacitance limits high-frequency response; suitable for audio-band and sub-MHz signal conditioning. |
Pinout & Package
MSB710-RT1G uses the SC-59 (SOT-23) plastic surface-mount package (Case 318D), measuring 2.90 × 1.50 × 1.15 mm with 1.90 mm lead pitch. Pin configuration follows Style 1: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Current-controlled input terminal | Accepts forward-biased base-emitter current to modulate collector current; requires series resistor to limit IB per hFE target. |
| 2 (Emitter) | Common reference node for PNP operation | Connected to higher potential rail in typical common-emitter switch; polarity reversal critical vs NPN layout. |
| 3 (Collector) | Output current terminal | Sinks current from load to emitter; voltage swing limited by V(BR)CEO and VCE(sat). |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free SC-59 package | Complies with RoHS Directive 2011/65/EU; eliminates lead contamination risk in reflow soldering and end-of-life recycling. |
| Guaranteed hFE ≥120 | Enables stable biasing in Class-A amplifiers without gain-dependent thermal drift compensation. |
| V(BR)EBO = −7.0 V | Permits safe base-emitter reverse bias up to −7 V, supporting level-shifting or protection diode integration. |
| TJ max = 150°C | Supports operation in sealed enclosures or high-ambient industrial environments without forced cooling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT710-7-F | Same SC-59 package, identical V(BR)CEO/IC/hFE specs; Diodes Incorporated part with ±5% hFE binning tolerance vs onsemi's min/max range. | Identical use in linear amplification and switching; validated in same PCB footprints. | Select when requiring tighter hFE consistency across production lots. |
| PN2907A | TO-92 through-hole package; same V(BR)CEO and IC, but lower PD (350 mW) and wider hFE spread (100–300). | Used where manual assembly or prototyping favors axial leads; not drop-in for SC-59 layouts. | Choose only for breadboard evaluation or legacy through-hole designs. |
Compared with MMBT710-7-F and PN2907A, the MSB710-RT1G offers guaranteed minimum hFE and Pb-free SC-59 compliance out-of-box, making it optimal for automated SMT production targeting consumer audio and automotive lighting subsystems.

FAQ
What is the pin configuration of the MSB710-RT1G?
The MSB710-RT1G uses Style 1 pinout in the SC-59 package: Pin 1 is Base, Pin 2 is Emitter, and Pin 3 is Collector. This matches JEDEC TO-236AB and is confirmed in the official onsemi datasheet revision 4. Layout must observe PNP polarity - emitter connects to higher potential than collector in normal operation. The MSB710-RT1G marking "CR M" identifies device code and Pb-free status.
Does the MSB710-RT1G support Pb-free reflow soldering?
Yes, the MSB710-RT1G is explicitly designated as Pb-free per its "G" suffix and "M" marking, compliant with J-STD-020 moisture sensitivity level 1 and RoHS Directive 2011/65/EU. It withstands peak reflow temperatures up to 260°C for 10 seconds. The MSB710-RT1G datasheet specifies no special pre-bake requirements due to its MSL-1 rating.
What is the minimum hFE guaranteed for MSB710-RT1G at −150 mA?
The MSB710-RT1G guarantees hFE ≥120 when tested at VCE = −10 Vdc and IC = −150 mAdc, per the Electrical Characteristics table in the January 2006 Rev. 4 datasheet. At higher current (−500 mA), minimum hFE drops to 40. This defined gain floor allows robust base resistor design for the MSB710-RT1G in production amplifiers.
Can MSB710-RT1G replace PN2907A in existing designs?
No direct replacement: MSB710-RT1G is SC-59 surface-mount while PN2907A is TO-92 through-hole - different footprints and thermal profiles. Though both are PNP transistors with matching V(BR)CEO (−50 V) and IC (−500 mA), the MSB710-RT1G has lower PD (200 mW vs 350 mW) and tighter hFE range. Redesign required for MSB710-RT1G integration.
What is the maximum operating temperature for MSB710-RT1G?
The MSB710-RT1G has a maximum junction temperature (TJ) of 150°C and storage temperature range of −55°C to +150°C. Derating begins above 25°C ambient at 1.6 mW/°C, based on its 200 mW PD rating. This makes the MSB710-RT1G suitable for under-hood automotive modules or enclosed industrial controls where ambient exceeds 85°C.
