Product details
Overview
TS20K80-T from Taiwan Semiconductor is a 20A, 800V standard bridge rectifier in TS4K in-line package, featuring 220A surge capability, 1.05V max forward voltage at 10A/25°C, and ultra-low 5μA reverse leakage at 25°C - used in on-board chargers and AC-DC front-end conversion stages.
For engineers reviewing the TS20K80-T datasheet, TS20K80-T pinout, TS20K80-T application, or TS20K80-T equivalent, key selection criteria include VRRM=800V, IFSM=220A, RθJL=1.3°C/W, TJ(max)=150°C, and TS4K mechanical compatibility with PCB-mount thermal management.
Technical Context
The TS20K80-T integrates four silicon diodes in a single-phase full-wave bridge configuration with in-line terminal layout. Its design supports high-reliability AC input rectification where repetitive peak reverse voltage must withstand 800V transients and sustained RMS input up to 560V.
Thermal performance is defined for mounting on a 4"×6"×0.25" aluminum heatsink: RθJC=1.2°C/W and RθJA=6.8°C/W confirm suitability for conduction-cooled industrial power supplies. Junction capacitance per diode is 65pF at 1MHz/4V, limiting high-frequency switching noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - maximum repetitive reverse voltage the bridge can block without breakdown |
| IF(AV) | 20 A - average forward current rating under specified thermal conditions |
| IFSM | 220 A - non-repetitive surge current handling for 8.3ms half-sine, critical for inrush protection |
| VF (max) | 1.05 V @ 10A, 25°C - forward voltage drop per diode, directly impacts conduction loss and thermal load |
| IR (max) | 5 μA @ 800V, 25°C - reverse leakage per diode, ensures low standby power loss in offline converters |
| RθJL | 1.3 °C/W - junction-to-lead thermal resistance, enables direct heatsink attachment via leads |
| TJ(max) | 150 °C - maximum allowable junction temperature, sets thermal derating envelope |
Pinout & Package
Package: TS4K - in-line, molded plastic case meeting UL 94V-0; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 1 whisker resistance; polarity marked on body.

Use Value: TS4K footprint and J-STD-002-compliant leads ensure reliable reflow assembly and long-term solder joint integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU20J-E4/51 | VRRM=600V (lower), IFSM=180A, same 20A IF, GBU package (larger footprint) | Limited to 600V systems; less surge margin for 277VAC+ applications | Select when cost sensitivity outweighs 800V requirement and board space permits GBU outline |
| GBU20K-E4/51 | VRRM=800V (same), IFSM=180A (lower), same 20A IF, GBU package | Lower surge tolerance may require upstream fusing in high-inrush designs | Choose for legacy GBU-compatible layouts where TS4K mounting isn't feasible |
Compared with GBU20J-E4/51 and GBU20K-E4/51, the TS20K80-T delivers higher surge robustness (220A vs. 180A) and a smaller TS4K footprint - advantageous for thermally dense, space-constrained AC-DC modules requiring 800V blocking.

FAQ
What is the maximum junction temperature rating for TS20K80-T?
The TS20K80-T has a maximum junction temperature (TJ(max)) of +150°C. This rating defines the upper thermal limit for safe continuous operation. Derating of forward current is required above +125°C case temperature, per the forward current derating curve in the datasheet. Maintaining TJ ≤ 150°C ensures long-term reliability and prevents parametric shift in VF and IR. The TS20K80-T achieves this with RθJL = 1.3°C/W when properly mounted.
Does TS20K80-T meet RoHS and halogen-free requirements?
Yes, the TS20K80-T is RoHS compliant and halogen-free per IEC 61249-2-21. These environmental qualifications are confirmed in the official Taiwan Semiconductor datasheet (Version A2208). The molding compound and plating materials are selected to satisfy both directives, making TS20K80-T suitable for export to EU, China, and other regulated markets without restriction.
What is the marking code printed on the TS20K80-T device body?
The TS20K80-T is marked "TS20K80" on its top surface, followed by green compound indicator (G), date code (YWW), and factory code (F). This marking aligns with the ordering code TS20K80-T and distinguishes it from other members of the TS20Kxx-T family (e.g., TS20K40, TS20K60). No additional suffixes or variants appear on the physical device.
How does the thermal resistance of TS20K80-T compare between junction-to-case and junction-to-lead?
The TS20K80-T specifies RθJC = 1.2°C/W and RθJL = 1.3°C/W. This near-identical value indicates that heat flows efficiently from junction to both case and leads - confirming the TS4K package's design intent for lead-mounted heatsinking. Unlike packages relying solely on case conduction, TS20K80-T allows effective thermal management through either method, provided leads are soldered to adequate copper area or clamped to an external heatsink.
Is TS20K80-T UL Recognized, and what is its file number?
Yes, the TS20K80-T is UL Recognized under File # E-326243. This recognition applies to the entire TS20Kxx-T family and covers dielectric strength, flammability (UL 94V-0), and construction compliance. It enables end-product safety certification without requiring additional component-level testing - a key advantage for OBC and industrial PSU designers targeting UL/CSA approval.
