BAWH56WT1G Equivalent & Substitute Parts

Part Overview

The BAWH56WT1G is a general-purpose rectifier diode manufactured by onsemi, rated for 70V DC reverse voltage with 200mA average rectified current. The device is packaged in SC-70 (SOT-323) surface mount configuration and is classified as a small signal diode with reverse recovery time of 6 nanoseconds. This component is actively produced and RoHS3 compliant.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical parameters. Identifying alternative sources ensures design flexibility, supply chain continuity, and access to devices with extended qualification or automotive-grade certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the BAWH56WT1G is determined by strict equivalence across the following critical parameters:

Reverse Voltage Rating: 70V maximum DC reverse voltage
Forward Current Capacity: 200mA average rectified current
Forward Voltage Drop: 1.25V maximum at 150mA
Reverse Recovery Time: 6 nanoseconds
Reverse Leakage Current: 2.5µA at 70V
Junction Capacitance: 2pF at 0V, 1MHz
Package Configuration: SC-70 (SOT-323) surface mount
Operating Temperature Range: -55°C to 175°C junction temperature

All substitute parts must maintain identical electrical performance within these parameters and support the same surface mount package footprint. Compliance certifications and grade designations do not affect electrical substitutability but may influence application suitability.

Engineering Selection Recommendations

BAWH56WT1G is the standard-grade variant suitable for general-purpose applications requiring 70V/200mA rectification performance. The device maintains active production status with established supply availability.

NSVBAWH56WT1G is the automotive-grade equivalent with AEC-Q101 qualification. This variant is electrically identical to the BAWH56WT1G across all specified parameters and is suitable for applications requiring automotive-grade component certification. The NSVBAWH56WT1G demonstrates higher inventory availability (6831 pieces versus 828 pieces).

Selection between these parts depends on application requirements:

Use BAWH56WT1G for standard industrial and consumer applications where automotive qualification is not required.
Use NSVBAWH56WT1G for automotive applications, systems requiring AEC-Q101 certification, or when higher inventory availability is advantageous.

Both parts are RoHS3 compliant, REACH unaffected, and support identical PCB footprints and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can NSVBAWH56WT1G replace BAWH56WT1G in existing designs?

A: Yes. The NSVBAWH56WT1G is electrically and mechanically equivalent to the BAWH56WT1G. All electrical parameters, package configuration, and operating temperature ranges are identical. The automotive-grade qualification of the NSVBAWH56WT1G does not affect compatibility with standard applications.

Q: What is the difference between BAWH56WT1G and NSVBAWH56WT1G?

A: The primary difference is grade designation and qualification. BAWH56WT1G is standard-grade, while NSVBAWH56WT1G is automotive-grade with AEC-Q101 qualification. Electrical performance, forward voltage, reverse voltage, current capacity, and package are identical.

Q: Are the package footprints identical?

A: Yes. Both parts use SC-70 (SOT-323) surface mount packaging. PCB layouts, solder pad dimensions, and component placement are interchangeable.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive industry standard qualification for discrete semiconductors. It specifies reliability and quality requirements for automotive applications. Components with this qualification undergo additional testing and validation.

Q: Can I use BAWH56WT1G in automotive applications?

A: BAWH56WT1G is not automotive-qualified. For automotive applications requiring AEC-Q101 certification, use NSVBAWH56WT1G.

Q: Are both parts RoHS compliant?

A: Yes. Both BAWH56WT1G and NSVBAWH56WT1G are RoHS3 compliant and REACH unaffected.

Q: What is the reverse recovery time specification?

A: Both parts specify 6 nanoseconds reverse recovery time, indicating small signal switching performance suitable for high-frequency rectification applications.

Q: Do these parts require different soldering profiles?

A: No. Both parts use identical SC-70 (SOT-323) surface mount packaging and support standard reflow soldering processes. Moisture sensitivity level is 1 (Unlimited) for both variants.
