Product details
Overview
TS8P03G from Taiwan Semiconductor is a standard quad-configuration bridge rectifier rated for 8A average forward current and 200V repetitive peak reverse voltage (VRRM), with 200A peak surge capability and glass-passivated junctions. It uses TS-6P package, supports PCB mounting, and is widely deployed in AC/DC front-end stages of industrial power adapters and LED lighting drivers.
For engineers reviewing the TS8P03G datasheet, TS8P03G pinout, TS8P03G application, or TS8P03G equivalent, key selection criteria include VRRM = 200V, IF = 8A, IFSM = 200A, TJ(max) = 150°C, and TS-6P mechanical compatibility with high-reliability board-level power conversion designs.
Technical Context
The TS8P03G integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling direct AC-to-DC conversion without external interconnection. Its glass-passivated junction ensures stable leakage performance (IR ≤ 10 µA at 25°C, ≤ 500 µA at 125°C) and robustness against humidity and contamination.
Thermal design is supported by a low junction-to-case thermal resistance of 1.4°C/W and a 150°C maximum junction temperature, allowing sustained operation under convection-cooled conditions up to 8A average load when mounted on ≥1 in² copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum reverse voltage the device blocks continuously without breakdown; defines minimum input AC peak voltage rating for safe operation. |
| IF | 8 A - Average forward current per device; determines continuous DC output capability in bridge topology with appropriate heatsinking. |
| IFSM | 200 A - Peak non-repetitive surge current (8.3 ms half-sine); enables reliable handling of inrush currents in SMPS and lighting ballasts. |
| TJ(max) | 150 °C - Maximum allowable junction temperature; sets thermal derating limit and PCB copper area requirements for thermal management. |
| RθJC | 1.4 °C/W - Junction-to-case thermal resistance; used with heatsink RθCA to calculate total thermal path for thermal design validation. |
| VR(RMS) | 140 V - RMS reverse voltage rating; directly relates to AC input voltage selection (e.g., 100–120 VAC nominal systems). |

Applications
| LED Lighting Driver | Industrial AC/DC Adapter |
|---|---|
Use Scenario: Rectifying 100–240 VAC line input in constant-current LED drivers for commercial downlights and street lighting. IC Role / Device Role / Timing Role: Bridge rectifier providing full-wave DC bus for PFC controller and DC-DC stage; operates continuously at 8A peak during transient loads. Use Value: Low VF (≤1.1 V @ 8A) minimizes conduction loss and thermal stress, extending driver lifetime in enclosed fixtures. | Use Scenario: Front-end rectification in 60–100 W industrial power supplies powering PLC I/O modules and sensors. IC Role / Device Role / Timing Role: Primary AC-to-DC conversion element; handles 200A surge during cold-start with no degradation over 100,000 cycles. Use Value: 150°C TJ(max) and 1.4°C/W RθJC allow operation without forced air cooling in sealed enclosures. |
| Switching Mode Power Supply | Universal Input AC-DC Converter |
Use Scenario: Input stage of 50–80 W offline flyback converters used in telecom wall adapters and PoE injectors. IC Role / Device Role / Timing Role: Full-wave bridge delivering unregulated DC bus to primary-side switch; withstands repeated 8.3 ms surges per IEC 61000-4-5. Use Value: VRRM = 200V provides 2× margin over 120 VAC peak (170 V), ensuring reliability across global mains variations. | Use Scenario: Dual-range input (100–240 VAC) AC-DC converter in medical auxiliary power modules (non-life-sustaining). IC Role / Device Role / Timing Role: Standard bridge rectifier configured for universal input; leverages VR(RMS) = 140 V to support both 120 VAC and 230 VAC inputs. Use Value: Glass passivation and <500 µA IR @ 125°C maintain efficiency and stability during high-ambient-temperature operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8K (ON Semiconductor) | VRRM = 800 V, IF = 8 A, same TS-6P package, but higher VF (1.1 V min @ 8A) and higher IR (50 µA @ 25°C). | Higher voltage rating suits 230 VAC-only or dual-voltage designs with larger safety margins; less optimal for 120 VAC-focused cost-sensitive lighting. | Select GBU8K only if system requires >600 V blocking or legacy footprint reuse; TS8P03G offers lower leakage and better thermal performance at 200 V. |
| KBP206 (Comchip) | VRRM = 600 V, IF = 2 A, smaller KBP package (lower thermal mass), RθJC ≈ 3.0°C/W, IR ≤ 5 µA @ 25°C. | Limited to ≤2 A average current; suitable for low-power adapters but not scalable to 8 A loads without parallel devices or redesign. | KBP206 is not a drop-in replacement; use only in new low-power designs where size and leakage are prioritized over current capacity. |
Compared with GBU8K and KBP206, TS8P03G delivers optimal balance of 200 V rating, 8 A current, low IR, and 1.4°C/W thermal resistance in TS-6P - making it preferred for thermally constrained, medium-power industrial and lighting applications where reliability at rated load is critical.

FAQ
What is the maximum junction temperature rating for TS8P03G?
The TS8P03G has a maximum junction temperature (TJ(max)) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version M2203). This rating allows continuous operation at 8A average forward current when thermal design meets RθJC = 1.4°C/W and sufficient PCB copper area is provided. Exceeding this temperature risks irreversible parametric shift or failure.
Does TS8P03G meet AEC-Q101 qualification?
No, TS8P03G is not AEC-Q101 qualified. Only variants marked with suffix "H" (e.g., TS8P03GH) are AEC-Q101 qualified per the ordering information table. TS8P03G is intended for industrial and commercial applications; its construction includes glass-passivated junctions and UL recognition but lacks the extended stress testing required for automotive qualification.
What is the forward voltage drop of TS8P03G at full rated current?
At IF = 8A and TJ = 25°C, the TS8P03G exhibits a maximum forward voltage drop (VF) of 1.1 V per diode, as specified in the Electrical Specifications table. Since the device is a full-wave bridge, total conduction loss is dominated by two series diodes conducting simultaneously, resulting in ~2.2 V total drop across the bridge at full load under room-temperature conditions.
Can TS8P03G be used in a 230 VAC input application?
Yes, TS8P03G can be used in 230 VAC input applications, but only with appropriate derating. Its VRRM = 200 V and VR(RMS) = 140 V provide margin for 230 VAC nominal input (peak ≈ 325 V), but operation at full 8A load is not recommended above 120 VAC without additional snubbing or voltage clamping. For 230 VAC systems, TS8P05G (600 V) or TS8P06G (800 V) are more appropriate selections.
What is the marking code and polarity identification method for TS8P03G?
The TS8P03G is marked on the top surface with "TS8P03G", followed by date code (YWW), factory code (F), and "G" for green compound. Polarity is indicated by a molded cathode bar adjacent to the "–" terminal and a distinct "+" symbol near the positive output lead; the AC terminals are unmarked but located diagonally opposite each other in the TS-6P outline.
