Product details
Overview
5.0SMDJ60A from Taiwan Semiconductor is a unidirectional 5000W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 60V working standoff voltage, 66.7–73.7V breakdown voltage at 1mA, and 96.8V clamping voltage at 51.7A peak pulse current. It delivers fast sub-1ps response and operates from –55°C to +175°C, designed for surge protection in DC power rails and I/O interfaces.
For engineers reviewing the 5.0SMDJ60A datasheet, 5.0SMDJ60A pinout, 5.0SMDJ60A application, or 5.0SMDJ60A equivalent, key selection criteria include clamping performance at 51.7A, thermal resistance (RθJA = 61°C/W), unidirectional polarity marking, moisture sensitivity level 1 compliance, and UL 94V-0 molding compound suitability for high-reliability industrial power systems.
Technical Context
The 5.0SMDJ60A uses a stacked-die construction to achieve 5000W peak pulse power handling under 10/1000μs waveform while maintaining low clamping ratio (VC/VBR ≈ 1.45). Its photo-glass passivated junction ensures stable leakage (<2µA at 60V) and long-term reliability under repeated transients.
Designed for automated SMT placement, it features matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Polarity is indicated by cathode band, and thermal performance is characterized on a 16mm × 16mm copper pad PCB per JEDEC standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A (Bourns) | Same DO-214AA package; lower PPPPM = 600W; VC = 96.8V @ 6.2A | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy surges | Select 5.0SMDJ60A when 5000W surge immunity is mandatory; SMBJ60A fits space-constrained designs with lower threat profiles. |
| SMCJ60A (Littelfuse) | DO-214AB package; identical PPPPM = 5000W; VBR = 66.7–73.7V; VC = 96.8V @ 51.7A | Functionally aligned for same high-energy surge use cases | SMCJ60A is a direct functional alternative with matching electrical specs and thermal performance; verify reel packaging and lead finish compatibility. |
Compared with SMBJ60A and SMCJ60A, the 5.0SMDJ60A provides identical clamping and surge rating to SMCJ60A but exceeds SMBJ60A by over 8× peak power-making it essential for infrastructure-grade surge immunity where single-event energy exceeds 100J.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ60A under standard test conditions?
The 5.0SMDJ60A has a maximum clamping voltage (VC) of 96.8 V when subjected to a 10/1000μs waveform peak pulse current of 51.7 A. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuits during surge events. The clamping performance remains stable across its operational junction temperature range (–55°C to +175°C), making the 5.0SMDJ60A suitable for harsh-environment applications where thermal derating must be minimized.
Does the 5.0SMDJ60A meet RoHS and halogen-free requirements?
Yes, the 5.0SMDJ60A is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating without lead or other restricted substances. These certifications are verified per TSC's material declarations and apply to all production lots shipped under ordering code 5.0SMDJ60A. Compliance documentation is available upon request for 5.0SMDJ60A procurement audits.
What is the thermal resistance profile of the 5.0SMDJ60A, and how does it affect PCB layout?
The 5.0SMDJ60A has RθJA = 61°C/W, RθJC = 17°C/W, and RθJL = 16°C/W when mounted on a 16mm × 16mm copper pad PCB per JEDEC standards. This means effective heat dissipation requires generous copper area connected to both terminals-especially the cathode-and thermal vias under the pad. For continuous power handling beyond 6.25W, forced airflow or external heatsinking is recommended. Layout guidelines for 5.0SMDJ60A are provided in TSC's DO-214AB footprint recommendations.
How does the 5.0SMDJ60A differ from the 5.0SMDJ60CA variant?
The 5.0SMDJ60A is unidirectional, while the 5.0SMDJ60CA is bidirectional-meaning the latter conducts in both directions and lacks polarity marking. The 5.0SMDJ60A has a forward voltage (VF) of 5 V at 100 A, whereas the 5.0SMDJ60CA exhibits symmetrical clamping in either polarity. Use 5.0SMDJ60A for DC rail protection with defined polarity; choose 5.0SMDJ60CA only for AC-coupled or floating signal lines where bidirectional clamping is required. Both share identical package, power rating, and thermal specs.
Is the 5.0SMDJ60A suitable for IEC 61000-4-5 surge testing at Level 4?
Yes, the 5.0SMDJ60A is rated for 5000W peak pulse power at 10/1000μs, which satisfies the 4kV open-circuit voltage / 2Ω source impedance requirement of IEC 61000-4-5 Level 4. When properly mounted on a PCB with adequate copper pour and coordinated with upstream current-limiting impedance, the 5.0SMDJ60A reliably clamps transients below 100V, protecting downstream 100V-rated components. System-level validation of 5.0SMDJ60A in your specific layout is still recommended per IEC 61000-4-5 test setup.
