SS36HR7G Equivalent & Substitute Parts

Part Overview

The SS36HR7G is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 60 V DC reverse voltage and 3 A average rectified current in a DO-214AB (SMC) surface mount package. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain electrical performance characteristics including forward voltage, reverse leakage current, and fast recovery speed specifications while accommodating various packaging and qualification requirements.

Substitute Part Grouping Explanation

Substitute parts for the SS36HR7G are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following parameters:

Core Electrical Requirements:

Voltage - DC Reverse (Vr) (Max): 60 V (exact match required)
Current - Average Rectified (Io): 3 A (exact match required for direct substitution)
Voltage - Forward (Vf) (Max) @ If: 700–750 mV @ 3 A (acceptable range)
Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (exact match required)
Current - Reverse Leakage @ Vr: 500 µA @ 60 V (acceptable match)

Mechanical Compatibility:

Mounting Type: Surface Mount (required)
Package / Case: DO-214AB, SMC (primary); DO-214AC, SMA; DO-214AA, SMB (alternative packages with same electrical ratings)

Compliance & Status:

RoHS Status: ROHS3 Compliant (required)
Moisture Sensitivity Level (MSL): 1 (Unlimited) (required)
Product Status: Active (preferred for new designs)

Grouping Categories:

Group 1 – Direct Electrical & Package Match (DO-214AB SMC): Parts with identical 60 V / 3 A ratings and SMC package. These are pin-compatible replacements.

Group 2 – Electrical Match with Alternative Packages (SMA, SMB): Parts with identical 60 V / 3 A ratings but different surface mount packages (DO-214AC SMA, DO-214AA SMB). These require PCB layout modification.

Group 3 – Higher Current Rating (60 V / 5 A): Parts with identical voltage rating but higher current capacity. These are electrically compatible but represent design upgrades.

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (DO-214AB SMC Package):

Select from CMSH3-60 BK PBFREE, CMSH3-60 TR13 PBFREE, B360-13-F, B360Q-13-F, or CDBC360-HF. All maintain 60 V / 3 A electrical specifications with forward voltage of 700 mV @ 3 A, which is within acceptable tolerance of the original 750 mV specification. B360Q-13-F and B360-13-F are preferred due to active product status and high inventory availability. CMSH3-60 variants from Central Semiconductor Corp provide equivalent performance with active status.

For Automotive Applications:

B360Q-13-F, B360A-13-F, B360AM-13-F, B360B-13-F, and B560CQ-13-F carry AEC-Q101 automotive qualification. B360Q-13-F maintains the SMC package and 3 A rating. B360A-13-F and B360AM-13-F use SMA package (DO-214AC) and require PCB layout modification. B360B-13-F uses SMB package (DO-214AA) and also requires layout modification.

For Higher Current Capacity:

B560C-13-F and B560CQ-13-F provide 5 A average rectified current while maintaining 60 V reverse voltage and SMC package compatibility. These are electrically compatible upgrades for applications requiring increased current margin. B560CQ-13-F includes AEC-Q101 qualification.

For Non-Automotive Applications with Standard Compliance:

CMSH3-60 BK PBFREE (bulk packaging) or CMSH3-60 TR13 PBFREE (tape & reel) from Central Semiconductor Corp provide cost-effective alternatives with active product status and equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can I use B360A-13-F or B360B-13-F as direct replacements for SS36HR7G?

A: B360A-13-F and B360B-13-F are electrically equivalent but use different surface mount packages (SMA and SMB respectively, versus the original SMC). They require PCB layout modification and cannot be used as direct pin-compatible replacements without redesign.

Q: What is the difference between CMSH3-60 BK PBFREE and CMSH3-60 TR13 PBFREE?

A: Both parts are electrically identical with 60 V / 3 A ratings and SMC packaging. The difference is packaging format: BK denotes bulk packaging, while TR13 denotes tape & reel format. Selection depends on assembly process requirements and order quantity.

Q: Can I substitute B560C-13-F (5 A) for the original 3 A SS36HR7G?

A: B560C-13-F is electrically compatible and maintains 60 V reverse voltage and SMC package. The higher 5 A current rating provides additional design margin and is a valid upgrade. Forward voltage remains 700 mV @ 5 A, within acceptable tolerance.

Q: Why do some substitute parts have lower reverse leakage current (100 µA vs. 500 µA)?

A: B360AM-13-F specifies 100 µA reverse leakage @ 60 V, compared to 500 µA for most alternatives. Lower reverse leakage represents improved performance and is acceptable for direct substitution. This does not create compatibility issues.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and MSL 1 (Unlimited) moisture sensitivity rating, matching the original SS36HR7G specifications.

Q: Which substitute part has the highest inventory availability?

A: B360A-13-F from Diodes Incorporated has the highest inventory at 285,400 pieces. However, this part uses SMA package (DO-214AC) and requires PCB layout modification. For SMC package with high availability, B360B-13-F has 125,401 pieces but uses SMB package. B360-13-F (SMC package) has 50,200 pieces available.

Q: What is the operating temperature range difference between SS36HR7G and substitute parts?

A: SS36HR7G operates -55°C to 150°C. CMSH3-60 variants operate -65°C to 150°C (extended low-temperature range). Diodes Incorporated B-series and Comchip CDBC360-HF operate -55°C to 150°C (matching original). All are acceptable for standard industrial applications.

Q: Can I use CDBC360-HF from Comchip Technology as a direct replacement?

A: Yes. CDBC360-HF maintains 60 V / 3 A electrical specifications, SMC package, and all compliance requirements. It is a direct pin-compatible replacement with active product status and 1,392 pieces in inventory.
