SMDJ16 Transient Voltage Suppressor (TVS) Diode – Equivalent & Substitute Parts

Part Overview

The SMDJ16 is a unidirectional transient voltage suppressor diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in surface-mount applications. Specified with a 16V reverse standoff voltage, 27.3V clamping voltage, and 3000W peak pulse power rating in DO-214AB (SMC) package, this component is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitute parts for the SMDJ16 are grouped based on the following critical electrical and mechanical parameters:

Voltage Parameters: Reverse standoff voltage of 16V and breakdown voltage minimum of 16.88V to 17.8V are the primary selection criteria. Clamping voltage must remain within acceptable limits (26V to 27.3V) to ensure circuit protection without exceeding component stress ratings.

Current and Power Ratings: Peak pulse current and power dissipation capability determine whether a substitute can handle the same transient energy. The SMDJ16 specifies 115.4A peak pulse current and 3000W peak pulse power. Substitutes are available in two current classes: 57.7A/1500W (reduced capability) and 115.4A/3000W (equivalent capability).

Package and Mounting: All substitutes maintain DO-214AB (SMC) surface-mount package compatibility, ensuring PCB layout and assembly process compatibility.

Temperature Range: Operating temperature specifications range from -55°C to -65°C minimum and 150°C to 175°C maximum across substitute options.

Compliance and Status: All substitute parts are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain stability.

Engineering Selection Recommendations

Full Electrical Equivalents (115.4A / 3000W Class):

SMDJ16A (Alpha & Omega Semiconductor Inc.), SMLJ16A (Bourns Inc.), SMLJ16A-TP (Micro Commercial Co), and TV30C160J-G (Comchip Technology) provide complete electrical equivalence to the SMDJ16 with matching peak pulse current and power ratings. All are active products with ROHS3 compliance. SMDJ16A and SMLJ16A offer the widest temperature range coverage (-55°C to 150°C), while SMLJ16A-TP extends to 175°C maximum. Selection among these should prioritize supply chain availability and packaging format (Tape & Reel vs. Bulk).

Reduced Capability Substitutes (57.7A / 1500W Class):

SZ1SMC16AT3G (Littelfuse Inc.), SMCJ16A-TP (Micro Commercial Co), SMCJ16AE3/TR13 (Microchip Technology), and TV15C160J-G (Comchip Technology) operate at half the peak pulse current and power rating. These are suitable only for applications where transient energy levels are lower than the original design specification. SZ1SMC16AT3G carries AEC-Q101 automotive qualification and maintains Littelfuse manufacturing continuity. SMCJ16A-TP and SMLJ16A-TP support extended temperature operation to 175°C.

Package Consideration:

SMCJ16A (EVVO Semi) uses DO-214AC (SMA) package, which differs from the standard DO-214AB (SMC) footprint. This substitution requires PCB layout verification and is not recommended for direct replacement without design review.

Frequently Asked Questions (FAQ)

Q: Can I use a 57.7A rated substitute in place of the 115.4A SMDJ16?

A: Only if your circuit's transient energy profile does not exceed the reduced power rating of 1500W. The 57.7A substitutes (SZ1SMC16AT3G, SMCJ16A-TP, SMCJ16AE3/TR13, TV15C160J-G) are electrically compatible at the voltage level but provide half the current-handling capacity. Use only when transient pulse energy is confirmed to be within the lower power budget.

Q: What is the difference between SMLJ16A and SMDJ16A?

A: Both provide 115.4A peak pulse current and 3000W power rating with 16V standoff voltage. SMLJ16A is manufactured by Bourns Inc., while SMDJ16A is from Alpha & Omega Semiconductor Inc. Electrical performance is equivalent; selection depends on supply availability and preferred manufacturer qualification.

Q: Is the SMCJ16A (EVVO Semi) a direct replacement?

A: SMCJ16A matches voltage and temperature specifications but uses DO-214AC (SMA) package instead of DO-214AB (SMC). Additionally, its 600W power rating is significantly lower than the SMDJ16's 3000W. This part is not recommended as a direct replacement without PCB redesign and application power budget verification.

Q: Which substitute offers the widest operating temperature range?

A: SMCJ16A-TP and SMLJ16A-TP both support -55°C to 175°C, providing the broadest temperature coverage. SZ1SMC16AT3G maintains the original -65°C to 150°C range from Littelfuse.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, meeting environmental and hazardous substance restrictions.

Q: What packaging formats are available?

A: Substitutes are supplied in Tape & Reel (TR), Cut Tape (CT) with Digi-Reel, or Bulk formats. Tape & Reel is standard for high-volume production; verify packaging availability with your supplier for your production volume requirements.
