Product details
Overview
NSVBC857BLT3G from onsemi is a PNP silicon general-purpose transistor in SOT-23 package, rated for −45 V VCEO, −50 V VCBO, −5.0 V VEBO, −100 mA IC continuous, and featuring hFE = 220–475 (at IC = −10 mA, VCE = −5.0 V). It serves as a low-power switching or linear amplification device in automotive signal conditioning circuits.
For engineers reviewing the NSVBC857BLT3G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, guaranteed hFE binning (B grade), −45 V breakdown rating, SOT-23 thermal performance (RJA = 556 °C/W on FR-5), and Pb-free/RoHS-compliant packaging.
Technical Context
This transistor operates in standard PNP active and saturation regions with verified VCE(sat) ≤ −0.65 V at IC = −100 mA / IB = −5.0 mA and VBE(sat) ≤ −0.9 V under same conditions. Its fT = 100 MHz supports high-speed switching up to ~35 ns rise time and ~40 ns fall time.
Designed for automotive-grade reliability, NSVBC857BLT3G meets AEC-Q101 stress testing requirements and is PPAP-capable. It exhibits stable DC current gain across −55 °C to +150 °C junction temperature range and maintains <4.5 pF output capacitance (Cob) at VCB = −10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V - Maximum collector-emitter voltage before breakdown; defines safe operating voltage headroom in PNP switch applications. |
| IC (cont.) | −100 mA - Continuous collector current limit; sets maximum steady-state load drive capability without derating. |
| hFE (min–max) | 220–475 - Guaranteed DC current gain range at IC = −10 mA, VCE = −5.0 V; enables predictable base drive sizing. |
| VCE(sat) | ≤ −0.65 V @ IC = −100 mA, IB = −5.0 mA - Low saturation voltage minimizes power loss in switching mode. |
| fT | 100 MHz - Current-gain bandwidth product; supports reliable operation in >10 MHz digital logic interface and pulse amplification. |
| Cob | ≤ 4.5 pF @ VCB = −10 V - Low output capacitance reduces switching delay and improves high-frequency response. |
| RJA | 556 °C/W (FR-5 board) - Thermal resistance determines required PCB copper area and ambient limits for 225 mW power dissipation. |
Pinout & Package
SOT-23 (TO-236) package, 2.90 mm × 1.30 mm × 1.00 mm body size, 1.90 mm lead pitch, JEDEC-standard footprint compatible with automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal; requires current-limited drive to bias transistor into active or saturation region. |
| 2 | Emitter | Current source terminal in PNP configuration; connected to higher potential (e.g., VCC) in common-emitter switches. |
| 3 | Collector | Current sink terminal; delivers load current to ground or lower-potential node when saturated. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and cabin applications per stress test requirements (HTOL, TC, HAST, etc.). |
| NSV prefix | Indicates automotive-specific traceability, control plan, and PPAP documentation support for OEM supply chains. |
| hFE binning (B grade) | Guaranteed 220–475 gain range ensures consistent switching thresholds and amplifier gain stability across production lots. |
| Pb-free / RoHS compliant | Meets global environmental regulations; SnAgCu solder compatibility confirmed for reflow profiles up to 260 °C peak. |
| Low VCE(sat) | ≤ −0.65 V at high current enables <65 mW conduction loss in 100 mA loads-critical for thermally constrained modules. |

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 |
|---|---|---|---|
| BC857BLT3G | No NSV prefix; not AEC-Q101 qualified; identical electrical specs and SOT-23 pinout. | Not approved for automotive production; suitable for industrial or consumer prototypes where qualification is not mandated. | Select BC857BLT3G only if AEC-Q101 compliance and PPAP documentation are unnecessary. |
| MMBT857LT3G | Same VCEO/IC/hFE specs but manufactured by ON Semiconductor under alternate part numbering; RoHS/Pb-free, no NSV prefix. | Lacks automotive traceability and site-specific control; functionally interchangeable in non-automotive designs. | Choose MMBT857LT3G when sourcing flexibility is prioritized over automotive audit trail requirements. |
Compared with NSVBC857BLT3G, BC857BLT3G omits automotive qualification while retaining full electrical equivalence, whereas MMBT857LT3G offers identical performance without NSV traceability-making NSVBC857BLT3G the sole choice for AEC-Q101–mandated vehicle subsystems.

FAQ
What is the maximum junction temperature rating for NSVBC857BLT3G?
The NSVBC857BLT3G has a specified junction and storage temperature range of −55 °C to +150 °C. This rating is validated per AEC-Q101 test conditions and supports operation in under-hood automotive environments and industrial enclosures with passive cooling. The NSVBC857BLT3G must be operated within this thermal envelope to maintain reliability and parametric stability.
Does NSVBC857BLT3G support Pb-free reflow soldering?
Yes, NSVBC857BLT3G is Pb-free and RoHS compliant, qualified for standard SnAgCu reflow profiles with peak temperatures up to 260 °C. Its SOT-23 package meets J-STD-020 moisture sensitivity level 1 (MSL-1), eliminating bake requirements prior to assembly. The NSVBC857BLT3G's terminations are matte tin-plated for robust wetting and intermetallic formation.
Is NSVBC857BLT3G pin-compatible with BC857BLT3G?
Yes, NSVBC857BLT3G uses the identical SOT-23 package and pinout (Pin 1: Base, Pin 2: Emitter, Pin 3: Collector) as BC857BLT3G. No PCB layout changes are needed when upgrading from BC857BLT3G to NSVBC857BLT3G-only documentation and supply chain controls differ due to the NSV prefix and AEC-Q101 qualification of the NSVBC857BLT3G.
What is the guaranteed hFE range for NSVBC857BLT3G at IC = −10 mA?
The NSVBC857BLT3G is binned to the "B" grade, guaranteeing hFE between 220 and 475 when tested at IC = −10 mA and VCE = −5.0 V. This range is documented in the Electrical Characteristics table of the official onsemi datasheet and applies across the full operating temperature range. Designers can rely on this hFE window for base resistor calculations in the NSVBC857BLT3G.
Can NSVBC857BLT3G be used in linear amplifier configurations?
Yes, NSVBC857BLT3G supports linear operation with verified VBE(on) = −0.6 to −0.82 V and stable hFE across collector currents from −2 mA to −100 mA. Its low noise figure (≤10 dB at 1 kHz) and predictable base-emitter voltage make it suitable for low-gain preamplifier stages and emitter-follower buffers. The NSVBC857BLT3G performs reliably in such roles when biased within its Safe Operating Area limits.
