Product details

Overview

NSV2SA2029M3T5G from onsemi is a PNP silicon general-purpose amplifier transistor in SOT-723 package, rated for −50 V V_(BR)CEO, −100 mA I_C, 265 mW P_D, with h_FE = 120–560 (typ. 210–460), and f_T = 140 MHz - used in low-power audio preamplifier stages and signal conditioning circuits in automotive body control modules.

For engineers reviewing the NSV2SA2029M3T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, low V_CE(sat) < 0.5 V at −50 mA/−5 mA drive, ESD robustness (HBM 2000 V), and SOT-723 footprint compatibility with space-constrained PCB layouts.

Technical Context

This PNP bipolar junction transistor operates in linear amplification mode with verified DC current gain spanning 120–560 across collector currents from 0.1 mA to 100 mA, and maintains stable f_T = 140 MHz at V_CE = −12 V, I_C = −2 mA, enabling mid-frequency small-signal amplification up to ~100 MHz.

Its thermal design supports operation from −55 °C to +150 °C junction temperature, with power dissipation limited to 265 mW on FR-4 board using minimum footprint - consistent with SOT-723 mechanical outline CASE 631AA (1.20 × 0.80 × 0.50 mm, 0.40 mm pitch).

Key Specifications

Parameter	Value and Actual Design Meaning
V_(BR)CEO	−50 V - maximum reverse voltage between collector and emitter before breakdown; defines safe operating range in common-emitter amplifier biasing.
I_C (max)	−100 mA - continuous collector current limit; sets upper bound for load-driving capability in active-region amplification.
P_D	265 mW - power dissipation on FR-4 PCB with minimum footprint; constrains thermal design margin in sealed enclosures.
h_FE	120–560 - DC current gain variation across production lot and operating conditions; enables predictable base drive sizing for gain-stable stages.
f_T	140 MHz - transition frequency at specified test condition; confirms usable bandwidth for RF front-end buffering and IF amplification.
V_CE(sat)	< 0.5 V at I_C = −50 mA, I_B = −5 mA - low saturation voltage ensures minimal voltage drop in switch-mode or saturated-driver applications.
ESD Rating	HBM 2000 V / MM 200 V - validated electrostatic discharge immunity; reduces need for external protection in assembly and field environments.

Pinout & Package

SOT-723 (CASE 631AA) is a 3-pin ultra-small surface-mount plastic package measuring 1.20 × 0.80 × 0.50 mm with 0.40 mm lead pitch, optimized for high-density PCB layouts where board area is constrained.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal for forward-biased PNP operation; requires negative bias relative to emitter to enable conduction.
2	Emitter	Current source terminal in PNP configuration; typically tied to higher potential (e.g., V_CC) in common-emitter amplifier topologies.
3	Collector	Output current sink terminal; connects to load or next stage; polarity inverted relative to NPN devices.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive electronics per stress-test requirements - supports use in under-hood and body-control applications without additional qualification effort.
Low V_CE(sat)	< 0.5 V enables efficient switching and reduced power loss in saturated driver configurations, e.g., LED dimming or relay control.
High h_FE range	120–560 allows consistent small-signal gain across temperature (−55 °C to +150 °C) and process variation, reducing calibration overhead.
Pb-free & RoHS compliant	Meets global environmental compliance mandates; "G" suffix denotes lead-free finish per JEDEC J-STD-020 reflow profile.

FAQ

What is the maximum collector-emitter voltage rating for NSV2SA2029M3T5G?

The NSV2SA2029M3T5G has a maximum collector-emitter breakdown voltage V_(BR)CEO of −50 Vdc at I_C = −1.0 mA and I_B = 0. This rating defines the absolute upper limit for reverse bias across the collector–emitter junction in active or cutoff operation - exceeding it risks irreversible avalanche failure. Derating is recommended for long-term reliability in automotive applications.

Is NSV2SA2029M3T5G suitable for high-frequency amplifier designs?

Yes, NSV2SA2029M3T5G delivers f_T = 140 MHz at V_CE = −12 V, I_C = −2 mA, making it suitable for small-signal amplification up to ~100 MHz. Its low COB = 3.5 pF and stable h_FE vs. frequency support IF-stage buffering and RF front-end gain blocks - though not intended for >500 MHz power amplification.

Does NSV2SA2029M3T5G require heatsinking in typical applications?

No, NSV2SA2029M3T5G dissipates only 265 mW maximum on FR-4 PCB with minimum footprint and operates up to +150 °C junction temperature - sufficient for most low-power amplifier and switching roles without external heatsinking. Thermal simulation is advised only when ambient exceeds +85 °C or power approaches 200 mW continuously.

What does the "NSV" prefix indicate in NSV2SA2029M3T5G?

The "NSV" prefix in NSV2SA2029M3T5G signifies onsemi's automotive-grade variant: it meets AEC-Q101 stress-test requirements, supports PPAP documentation, and includes enhanced traceability and site-specific process controls - distinguishing it from the commercial-grade 2SA2029M3T5G which shares identical electrical specs but lacks automotive qualification.

Can NSV2SA2029M3T5G replace an NPN transistor in a circuit?

No - NSV2SA2029M3T5G is a PNP transistor and cannot directly replace an NPN device without reversing biasing, swapping supply polarity, and redesigning surrounding passive components. Its complementary NPN counterpart is NSV2SC4617T1G; substitution requires full schematic and layout validation due to polarity inversion and gain asymmetry.
