SMF16A-TP Transient Voltage Suppressor Diode - Equivalent & Substitute Parts

Part Overview

The SMF16A-TP is a unidirectional Zener transient voltage suppressor diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection in surface-mount applications. The device features a 16V reverse standoff voltage with a 26V maximum clamping voltage and 7.7A peak pulse current capability in a SOD-123FL package. This part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide design flexibility, alternative sourcing options, and inventory availability across multiple manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMF16A-TP is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 16V
• Voltage - Breakdown (Min): 17.8V
• Voltage - Clamping (Max) @ Ipp: 26V
• Current - Peak Pulse (10/1000µs): 7.7A
• Power - Peak Pulse: 200W
• Type: Zener, Unidirectional
• Mounting Type: Surface Mount
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

All identified substitute parts maintain identical electrical performance specifications across voltage, current, and power ratings. Package variations (SOD-123F, SOD-123FL, DO-219AB/SMF) are mechanically compatible within the SMF family footprint classification. All substitutes are active products from established manufacturers with full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical equivalence to the SMF16A-TP across voltage clamping, peak pulse current, and power dissipation specifications. Selection among these alternatives is based on:

Manufacturer Availability: SMF16A-T13 (Littelfuse) offers the highest inventory at 19,420 units. SMF16A (MDD) provides 20,954 units. SMF16A-E3-08 (Vishay) maintains 3,400 units with extended temperature range to -65°C. SMF16A_R1_00001 (Panjit) provides 4,001 units.

Regulatory Compliance: All parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, meeting standard industrial procurement requirements.

Temperature Performance: SMF16A-TP and SMF16A-E3-08 both support the extended operating range of -65°C to 175°C, providing thermal margin for demanding applications. Alternative parts operate within -55°C to 150°C range.

Package Compatibility: SOD-123F and DO-219AB (SMF) packages are mechanically interchangeable within standard surface-mount assembly processes. Footprint verification against PCB design is required for DO-219AB variant.

Frequently Asked Questions (FAQ)

Q: Can SMF16A-E3-08 (Vishay) be used as a direct replacement for SMF16A-TP?

A: Yes. The SMF16A-E3-08 maintains identical electrical specifications (16V standoff, 26V clamp, 7.7A peak pulse, 200W power) and full RoHS3/MSL 1 compliance. The DO-219AB package footprint is mechanically compatible with SOD-123F in standard surface-mount applications. Verify PCB layout compatibility before assembly.

Q: What is the difference between SMF16A-TP and SMF16A (MDD)?

A: Both parts are electrically identical with matching voltage, current, and power ratings. The primary difference is manufacturer (Micro Commercial Co vs. MDD) and package designation (SOD-123FL vs. SMF/SOD-123FL). Inventory availability differs significantly (2,200 vs. 20,954 units).

Q: Are there temperature range limitations when substituting parts?

A: SMF16A-TP and SMF16A-E3-08 support -65°C to 175°C operation. SMF16A-T13, SMF16A (MDD), and SMF16A_R1_00001 operate within -55°C to 150°C. For applications requiring full -65°C to 175°C range, use SMF16A-TP or SMF16A-E3-08.

Q: Is the Littelfuse SMF16A-T13 compatible with existing PCB designs for SMF16A-TP?

A: Yes. Both use SOD-123F package with identical pinout and footprint. No PCB layout modifications are required for direct substitution.

Q: What does the capacitance specification (343pF @ 1MHz) on SMF16A-E3-08 indicate?

A: This parameter is provided only for the Vishay part. It represents junction capacitance at 1MHz frequency and does not affect substitution eligibility. All parts maintain equivalent transient suppression performance.

Q: Can these parts be used interchangeably in high-frequency applications?

A: All substitute parts are rated for general-purpose transient voltage suppression. Specific high-frequency performance characteristics are not provided in the parameter set. Application-specific testing is required for frequency-dependent circuit designs.

Q: What is the significance of the base product number SMF16?

A: SMF16 identifies the core product family across all manufacturers. Suffix variations (A, -T13, -E3-08, _R1_00001) indicate manufacturer-specific part numbering and packaging options while maintaining the same electrical specifications.
