Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RB706WM-40TL is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Diode Configuration: 1 Pair Series Connection
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): 30 mA
• Voltage - Forward (Vf) (Max) @ If: 370 mV @ 1 mA
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed
• Operating Temperature - Junction (Max): 125°C
• Package / Case: SC-89, SOT-490
• Supplier Device Package: EMD3F

Variable Parameters Permitting Substitution:

• Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®)
• Product Status (Active vs. Not For New Designs)
• Automotive qualification and AEC-Q101 certification
• Current - Reverse Leakage @ Vr (within acceptable range)
• Moisture Sensitivity Level (MSL)

All identified substitute parts maintain identical electrical performance and physical package specifications, ensuring direct functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

RB706WM-40TL (Primary Part - Active Status)

The RB706WM-40TL is the recommended selection for new designs and ongoing production. This part maintains Active product status with the highest inventory availability (3421 units). It provides standard-grade Schottky diode array performance with MSL 1 (Unlimited) moisture sensitivity rating, suitable for applications with standard environmental requirements.

RB706WM-40FHTL (Alternative - Not For New Designs)

The RB706WM-40FHTL is electrically identical to the primary part but carries Not For New Designs status. This part is qualified to automotive standards (AEC-Q101) and supplied in Cut Tape & Digi-Reel® packaging format. Selection of this part is appropriate only for legacy design support or when automotive qualification is required and packaging format compatibility exists with manufacturing equipment. Inventory availability is limited (856 units).

RB715WMFHTL (Alternative - Active Status)

The RB715WMFHTL is an Active product offering automotive-grade qualification (AEC-Q101) with equivalent electrical performance. This part differs in reverse leakage current specification (1 µA @ 10 V versus 500 nA @ 30 V) and carries MSL 3 (168 Hours) moisture sensitivity rating. Selection is appropriate for automotive applications requiring AEC-Q101 certification. Inventory availability is high (3764 units). The higher MSL rating requires compliance with moisture control procedures during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can RB706WM-40FHTL be used as a direct replacement for RB706WM-40TL in production?

A: RB706WM-40FHTL is electrically and mechanically compatible with RB706WM-40TL. However, the part carries Not For New Designs status. The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Compatibility depends on manufacturing equipment capability to process the alternative packaging format. Automotive qualification (AEC-Q101) is an additional feature not present in the primary part.

Q: What is the difference between RB706WM-40TL and RB715WMFHTL?

A: Both parts are Active products with identical electrical specifications for reverse voltage (40 V), rectified current (30 mA), and forward voltage (370 mV @ 1 mA). The RB715WMFHTL includes automotive-grade qualification (AEC-Q101) and carries a higher Moisture Sensitivity Level (MSL 3 versus MSL 1). The reverse leakage current specification differs: RB715WMFHTL specifies 1 µA @ 10 V while RB706WM-40TL specifies 500 nA @ 30 V. Selection between these parts depends on automotive qualification requirements and moisture control capabilities during manufacturing and storage.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use SC-89, SOT-490 surface mount package with EMD3F supplier device package designation. Physical footprint and pin configuration are identical, enabling direct PCB layout compatibility.

Q: What does MSL 1 (Unlimited) versus MSL 3 (168 Hours) mean for component handling?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and does not require special moisture control during storage or handling. MSL 3 (168 Hours) requires that the component be used within 168 hours of package opening if stored in uncontrolled humidity environments. Components with MSL 3 rating must be stored in moisture barrier bags with desiccant and require bake-out procedures if moisture absorption occurs.

Q: Why would I select RB706WM-40FHTL if it is Not For New Designs?

A: RB706WM-40FHTL is appropriate for supporting existing designs that are already in production or for legacy product maintenance. The Not For New Designs status indicates Rohm Semiconductor does not recommend this part for new circuit designs. However, it remains available for existing applications where design changes are not feasible or cost-effective.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts carry ROHS3 Compliant status and REACH Unaffected designation, meeting environmental and regulatory requirements for commercial and industrial applications.
