CSDD-16M TR13 Equivalent & Substitute Parts

Part Overview

The CSDD-16M TR13 is a 600V 16A Sensitive Gate SCR (Silicon Controlled Rectifier) in D2PAK surface mount packaging, manufactured by Central Semiconductor Corp. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The sensitive gate configuration enables reliable triggering at reduced gate current levels, suitable for applications requiring low-power gate drive circuits.

Substitute Part Grouping Explanation

Substitution of the CSDD-16M TR13 is constrained by the following critical parameters:

Voltage Rating: 600V off-state voltage is mandatory for direct substitution
Current Rating: 16A RMS on-state current defines the load-carrying capacity
Gate Sensitivity: Vgt ≤ 1.5V and Igt ≤ 15mA establish the gate trigger characteristics
Package Compatibility: TO-263-3 (D2PAK) surface mount package with identical pinout
Temperature Range: -40°C to 125°C junction temperature operating window
Device Type: SCR or functionally equivalent thyristor device

The substitute part Q6016NH3RP (Littelfuse) is a TRIAC Alternistor device. While TRIACs and SCRs differ in bidirectional conduction capability, the Q6016NH3RP meets the voltage, current, temperature, and package requirements. TRIAC substitution is valid only in applications where bidirectional current control is acceptable or beneficial.

Engineering Selection Recommendations

The Q6016NH3RP represents the primary substitute for the obsolete CSDD-16M TR13 based on electrical parameter alignment and active product status. Key selection factors:

Voltage and Current Ratings: Both devices are rated 600V / 16A RMS, ensuring equivalent load-handling capability
Gate Trigger Parameters: Q6016NH3RP exhibits lower Vgt (1.3V vs. 1.5V) and slightly higher Igt (20mA vs. 15mA), both within acceptable design margins for gate drive circuits
Surge Current: Q6016NH3RP surge ratings (167A, 200A) exceed the CSDD-16M TR13 (160A), providing improved transient protection
Product Status: Q6016NH3RP is active and widely available, eliminating obsolescence risk
Compliance: Q6016NH3RP is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements
Package Compatibility: Identical TO-263-3 (D2PAK) pinout enables direct PCB substitution

Device type difference: Q6016NH3RP is a TRIAC (bidirectional thyristor) versus CSDD-16M TR13 (unidirectional SCR). TRIAC substitution is valid for AC switching applications or where bidirectional control is acceptable. For DC-only or unidirectional applications, verify that bidirectional conduction does not compromise circuit function.

Frequently Asked Questions (FAQ)

Q: Can Q6016NH3RP directly replace CSDD-16M TR13 in all applications?

A: Direct PCB substitution is possible due to identical TO-263-3 (D2PAK) pinout and matching voltage/current ratings. However, functional compatibility depends on application type. Q6016NH3RP is a TRIAC (bidirectional) while CSDD-16M TR13 is an SCR (unidirectional). In DC circuits or applications requiring unidirectional control, verify that bidirectional conduction is acceptable before substitution.

Q: What are the key electrical differences between these devices?

A: Both devices share 600V off-state voltage, 16A RMS on-state current, and -40°C to 125°C operating range. Q6016NH3RP has lower gate trigger voltage (1.3V vs. 1.5V) and higher gate trigger current (20mA vs. 15mA). Q6016NH3RP surge ratings (167A, 200A) exceed CSDD-16M TR13 (160A). The fundamental difference is conduction direction: SCR conducts unidirectionally; TRIAC conducts bidirectionally.

Q: Is the D2PAK package identical between both parts?

A: Yes. Both CSDD-16M TR13 and Q6016NH3RP use TO-263-3 (D2PAK) surface mount packaging with identical pinout: Gate, Cathode/MT2, and Anode/MT1 (with tab). No PCB layout modifications are required for physical substitution.

Q: What compliance certifications apply to Q6016NH3RP?

A: Q6016NH3RP is ROHS3 compliant and REACH unaffected. ECCN classification is EAR99 for both devices. HTSUS code is 8541.30.0080 for both devices.

Q: Are there inventory considerations for this substitution?

A: CSDD-16M TR13 is obsolete with limited stock (1033 pcs reported). Q6016NH3RP is active production with established supply chains (955 pcs reported in reference inventory). For new designs or long-term support, Q6016NH3RP is the recommended choice.
