Product details
Overview
5.0SMDJ64A from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 5000W peak pulse power at 10/1000μs, 64V working standoff voltage, and 103V maximum clamping voltage at 48.6A peak current. It delivers fast response (<1.0ps), operates from −55°C to +175°C, and is used for I/O interface and AC/DC power supply surge protection.
For engineers reviewing the 5.0SMDJ64A datasheet, 5.0SMDJ64A pinout, 5.0SMDJ64A application, or 5.0SMDJ64A equivalent, key selection criteria include clamping voltage (103V), breakdown voltage range (71.1–78.6V), thermal resistance (RθJL = 16°C/W), unidirectional polarity, and RoHS/halogen-free compliance for industrial power rail protection.
Technical Context
The 5.0SMDJ64A uses a stacked-die construction with photo-glass passivated junction for stable avalanche performance under repetitive transients. Its unidirectional configuration provides low forward voltage (5V @ 100A) and precise reverse standoff (64V), enabling reliable overvoltage clamping without forward conduction during normal operation.
Designed for automated SMT placement, it meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity. Thermal performance is characterized on a 16mm × 16mm copper pad PCB, with RθJA = 61°C/W and RθJC = 17°C/W, supporting high-power transient suppression in compact layouts.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Lower peak power (600W), same DO-214AA package, 103V clamping | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy transients | Select 5.0SMDJ64A where 5000W surge immunity is required; SMBJ64A only for cost-sensitive, low-risk environments |
| SMCJ64A | Same 5000W rating and DO-214AB package, but 107V clamping (vs. 103V) | Higher clamping increases risk to 100V-rated downstream devices | 5.0SMDJ64A offers tighter clamping margin; use SMCJ64A only if layout constraints require alternate marking or sourcing flexibility |
Compared with SMBJ64A and SMCJ64A, the 5.0SMDJ64A delivers identical package and power rating to SMCJ64A but with 4V lower clamping voltage-critical for protecting marginally rated ICs-while outperforming SMBJ64A by >8× pulse power capacity for mission-critical surge zones.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ64A under a 10/1000μs surge?
The 5.0SMDJ64A has a maximum clamping voltage (VC) of 103 V when subjected to its rated peak pulse current of 48.6 A under the standardized 10/1000μs waveform. This value is guaranteed across temperature and production lot, ensuring consistent overvoltage protection for downstream components in designs relying on the 5.0SMDJ64A.
Is the 5.0SMDJ64A unidirectional or bidirectional, and how is polarity identified?
5.0SMDJ64A is a unidirectional TVS diode. Polarity is marked by a cathode band on the DO-214AB (SMC) package body; the banded end is the cathode, which must be connected toward the higher-potential side of the protected line. This configuration enables low-leakage reverse blocking and controlled forward conduction only during fault conditions.
What is the thermal resistance from junction to lead (RθJL) for the 5.0SMDJ64A, and why does it matter?
The 5.0SMDJ64A has a typical junction-to-lead thermal resistance (RθJL) of 16°C/W, measured on a 16mm × 16mm copper pad PCB. This low value enables efficient heat transfer from the silicon die to the PCB copper, critical for sustaining multiple 5000W transients without exceeding the 175°C maximum junction temperature-directly impacting reliability in high-surge-frequency applications.
Does the 5.0SMDJ64A meet RoHS and halogen-free standards?
Yes, the 5.0SMDJ64A is RoHS compliant and halogen-free per IEC 61249-2-21. These certifications are confirmed in the official Taiwan Semiconductor datasheet (Version D2102) and verified through material declarations, making the 5.0SMDJ64A suitable for environmentally regulated markets including EU, Japan, and North America.
What is the moisture sensitivity level (MSL) of the 5.0SMDJ64A, and how should it be handled before reflow?
The 5.0SMDJ64A has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without baking prior to reflow soldering. This simplifies SMT assembly logistics and eliminates floor-life tracking requirements for the 5.0SMDJ64A in production environments.
