Key Parameters

Substitute Part Grouping Explanation

Substitution of the UFS315J/TR13 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 3 A
• Package / Case: DO-214AB, SMC (Surface Mount)
• Mounting Type: Surface Mount
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 10 µA @ 150 V

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: 900–950 mV @ 3 A
• Reverse Recovery Time (trr): 25–35 ns
• Operating Temperature - Junction: -55°C to 150°C or higher
• Capacitance @ Vr, F: 45 pF @ 4V, 1MHz (when specified)

All three substitute parts (ES3C, ES3C-13-F, ES3C-E3/57T) meet the mandatory equivalence parameters and fall within allowable variation ranges for forward voltage and reverse recovery time.

Parameter Comparison

Engineering Selection Recommendations

UFS315J/TR13 (Microchip Technology)

• Primary selection for applications with no RoHS compliance requirement
• Supports extended junction temperature range to 175°C
• RoHS non-compliant status requires verification against end-product regulatory requirements

ES3C (Taiwan Semiconductor Corporation)

• Direct electrical equivalent with ROHS3 compliance
• Highest inventory availability (10,200 pcs)
• Reverse recovery time specification of 35 ns remains within fast recovery classification
• Operating temperature limited to 150°C; verify thermal requirements for applications exceeding this range

ES3C-13-F (Diodes Incorporated)

• ROHS3 compliant with improved forward voltage specification (900 mV vs. 950 mV @ 3 A)
• Fastest reverse recovery time (25 ns) among substitute options
• Tape & Reel packaging matches original part format
• Operating temperature limited to 150°C

ES3C-E3/57T (Vishay General Semiconductor - Diodes Division)

• ROHS3 compliant with improved forward voltage specification (900 mV vs. 950 mV @ 3 A)
• Reverse recovery time matches original specification (30 ns)
• Highest inventory availability (18,900 pcs)
• Operating temperature limited to 150°C

All substitute parts maintain electrical equivalence within specified parameters. Selection between substitutes depends on compliance requirements, thermal operating range, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can ES3C, ES3C-13-F, and ES3C-E3/57T be used interchangeably with UFS315J/TR13?

A: Yes, within the specified electrical and thermal operating parameters. All three substitute parts meet the mandatory equivalence criteria: 150 V reverse voltage rating, 3 A average rectified current, DO-214AB SMC package, and fast recovery classification. Verify that the operating temperature range of 150°C maximum (for all substitutes) is acceptable for your application, as the original UFS315J/TR13 supports up to 175°C.

Q: What is the difference in forward voltage between the original part and substitutes?

A: The UFS315J/TR13 specifies 950 mV maximum forward voltage at 3 A. ES3C matches this specification at 950 mV. ES3C-13-F and ES3C-E3/57T both specify 900 mV maximum at 3 A, representing a 50 mV improvement. This lower forward voltage reduces power dissipation in the diode and may improve circuit efficiency.

Q: Are there differences in reverse recovery time?

A: Yes. The UFS315J/TR13 specifies 30 ns reverse recovery time. ES3C specifies 35 ns, ES3C-13-F specifies 25 ns, and ES3C-E3/57T specifies 30 ns. All values remain within the fast recovery classification (≤ 500 ns). Applications sensitive to switching transients should verify compatibility with the specific trr value.

Q: What is the significance of RoHS compliance status?

A: The UFS315J/TR13 is RoHS non-compliant, while all three substitute parts are ROHS3 compliant. If your end product requires RoHS certification or compliance with EU Directive 2011/65/EU, substitute parts must be selected. Verify RoHS requirements with your product specification and regulatory requirements.

Q: Can I use these parts in applications exceeding 150°C junction temperature?

A: The UFS315J/TR13 supports junction temperatures to 175°C. All substitute parts are rated to 150°C maximum. If your application requires operation above 150°C, the original UFS315J/TR13 is the only option among these parts. Verify thermal design and operating conditions to confirm actual junction temperature.

Q: Are the packaging formats identical?

A: All parts use DO-214AB SMC surface mount package. The UFS315J/TR13 and ES3C-13-F are supplied in Tape & Reel (TR) format. ES3C packaging format is not specified in available data. ES3C-E3/57T is supplied in Tape & Reel (TR) format. Verify packaging format requirements for your assembly process.

Q: What inventory levels are available?

A: UFS315J/TR13: 755 pcs; ES3C: 10,200 pcs; ES3C-13-F: 10,300 pcs; ES3C-E3/57T: 18,900 pcs. Substitute parts offer significantly higher inventory availability for supply chain continuity.
