Substitute Part Grouping Explanation

Substitute parts for the BYG10D-M3/TR are grouped into two categories based on electrical equivalence and manufacturer designation:

Parametric Equivalents (Vishay BYG10 Series): Parts BYG10D-E3/TR and BYG10D-E3/TR3 are direct parametric equivalents manufactured by Vishay. These parts maintain identical electrical specifications: 200 V reverse voltage, 1.5 A average rectified current, 1.15 V forward voltage at 1.5 A, 4 µs reverse recovery time, and 1 µA reverse leakage current at 200 V. The primary distinction is packaging format: BYG10D-E3/TR is supplied in Cut Tape (CT) & Digi-Reel® format, while BYG10D-E3/TR3 is supplied in Tape & Reel (TR) format. Both maintain the DO-214AC (SMA) package specification and RoHS3 compliance.

Manufacturer Recommended Alternatives (STMicroelectronics STTH Series): Parts STTH102A, STTH102AY, STTH1R02A, and STTH2R02A are STMicroelectronics alternatives that satisfy the 200 V reverse voltage requirement and DO-214AC (SMA) package specification. These parts employ Standard technology with Fast Recovery characteristics (≤500 ns) rather than Avalanche technology. Current ratings vary: STTH102A and STTH102AY are rated for 1 A, STTH1R02A for 1.5 A, and STTH2R02A for 2 A. Forward voltage specifications range from 970 mV to 1 V depending on current rating. All alternatives maintain RoHS3 compliance and surface mount DO-214AC (SMA) package compatibility.

Parameter Comparison

Part Number	Manufacturer	Technology	Vr (Max) [V]	Io [A]	Vf (Max) [V]	trr [µs/ns]	Package	RoHS Status
BYG10D-M3/TR	Vishay	Avalanche	200	1.5	1.15 @ 1.5 A	4 µs	DO-214AC (SMA)	ROHS3
BYG10D-E3/TR	Vishay	Avalanche	200	1.5	1.15 @ 1.5 A	4 µs	DO-214AC (SMA)	ROHS3
BYG10D-E3/TR3	Vishay	Avalanche	200	1.5	1.15 @ 1.5 A	4 µs	DO-214AC (SMA)	ROHS3

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalents): BYG10D-E3/TR and BYG10D-E3/TR3 are direct parametric replacements for BYG10D-M3/TR. Both parts are manufactured by Vishay, maintain identical electrical specifications, and carry Active product status with RoHS3 compliance. Selection between these two should be based on packaging format requirements: BYG10D-E3/TR for Cut Tape & Digi-Reel® applications, or BYG10D-E3/TR3 for Tape & Reel applications.

Alternative Substitutes (STMicroelectronics): STTH102A, STTH102AY, STTH1R02A, and STTH2R02A are manufacturer-recommended alternatives from STMicroelectronics. These parts satisfy the 200 V reverse voltage and DO-214AC (SMA) package requirements. STTH1R02A provides the closest current rating match at 1.5 A. All alternatives are Active product status with RoHS3 compliance. The primary electrical difference is the use of Standard technology with Fast Recovery characteristics instead of Avalanche technology, resulting in significantly lower reverse recovery times (20–30 ns versus 4 µs).

Current Rating Considerations: STTH102A and STTH102AY are rated for 1 A average rectified current, which is lower than the BYG10D-M3/TR specification of 1.5 A. These parts are suitable only for applications where the actual operating current does not exceed 1 A. STTH1R02A matches the 1.5 A rating exactly. STTH2R02A provides 2 A capability for applications requiring higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can BYG10D-E3/TR and BYG10D-E3/TR3 be used interchangeably with BYG10D-M3/TR?

A: Yes. BYG10D-E3/TR and BYG10D-E3/TR3 are parametric equivalents with identical electrical specifications. The difference is packaging format: BYG10D-E3/TR uses Cut Tape & Digi-Reel® format, while BYG10D-E3/TR3 uses Tape & Reel format. Selection depends on your assembly equipment and supply chain requirements.

Q: What is the difference between Avalanche and Standard technology diodes?

A: The BYG10D-M3/TR uses Avalanche technology with a reverse recovery time of 4 µs. The STMicroelectronics alternatives use Standard technology with Fast Recovery characteristics, resulting in reverse recovery times of 20–30 ns. Avalanche diodes provide superior reverse voltage protection through controlled breakdown, while Standard Fast Recovery diodes prioritize switching speed. Technology selection depends on application requirements for transient protection versus switching performance.

Q: Can STTH102A or STTH102AY replace BYG10D-M3/TR in all applications?

A: STTH102A and STTH102AY are rated for 1 A average rectified current, which is lower than the BYG10D-M3/TR specification of 1.5 A. These parts are suitable only for applications where actual operating current does not exceed 1 A. For applications requiring the full 1.5 A rating, use STTH1R02A instead.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. BYG10D-M3/TR, BYG10D-E3/TR, BYG10D-E3/TR3, STTH102A, STTH102AY, STTH1R02A, and STTH2R02A are all RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the operating temperature range for each substitute?

A: BYG10D-M3/TR, BYG10D-E3/TR, and BYG10D-E3/TR3 operate from -55°C to 150°C junction temperature. STTH102A operates to 175°C maximum. STTH102AY (Automotive grade) operates from -40°C to 175°C. STTH1R02A and STTH2R02A operate to 175°C maximum. Select based on your application's thermal requirements.

Q: Is the DO-214AC (SMA) package identical across all parts?

A: Yes. All listed parts use the DO-214AC (SMA) surface mount package specification, ensuring mechanical and footprint compatibility on printed circuit boards.

Q: What is the difference between BYG10D-M3/TR and BYG10D-E3/TR packaging?

A: BYG10D-M3/TR is supplied in Tape & Reel (TR) format. BYG10D-E3/TR is supplied in Cut Tape (CT) & Digi-Reel® format. Both contain identical components; the difference is in supply and handling format for assembly operations.
