Product details
Overview
PU6BC from Taiwan Semiconductor is a 6A, 100V ultra-fast surface-mount rectifier in DO-214AB (SMC) package, featuring 25 ns reverse recovery time, 0.85 V forward voltage at 6A/25°C, and 160 A surge current capability. It serves as a primary output rectifier in high-frequency DC/DC converters for telecom and industrial power supplies.
For engineers reviewing the PU6BC datasheet, PU6BC pinout, PU6BC application, or PU6BC equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, ultra-fast trr ≤25 ns, low RθJL of 12 °C/W, and suitability for automated SMT assembly with J-STD-020 Level 1 moisture sensitivity.
Technical Context
The PU6BC employs planar silicon technology to achieve low conduction loss and fast switching performance. Its single-die configuration supports unidirectional conduction with cathode-band polarity marking and operates across -55°C to +175°C junction temperature range.
Thermal design is enabled by validated junction-to-lead resistance of 12 °C/W on 16 mm × 16 mm Cu pad PCBs, while electrical behavior is characterized under pulsed conditions: 0.3 ms for VF, 30 ms for IR, and standardized di/dt test conditions for trr and Qrr.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/snubber circuits |
| IF | 6 A - Continuous average forward current rating at TL = 110°C on standard PCB; sets thermal derating baseline |
| trr | 25 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >1 MHz switching in resonant topologies |
| VF | 0.85 V @ 6 A, 25°C - Forward drop directly impacts conduction loss and thermal rise in high-current paths |
| RθJL | 12 °C/W - Junction-to-lead thermal resistance measured on 16 mm × 16 mm Cu pad; enables direct heatsinking via PCB copper |
| IFSM | 160 A @ 8.3 ms - Non-repetitive surge rating; supports inrush and fault-current handling in SMPS outputs |
| CJ | 110 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency EMI and snubber sizing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-6EWH01-M3/45 | Same 100 V VRRM, 6 A IF, but trr = 35 ns; RθJA = 65 °C/W vs. PU6BC's 57 °C/W | Higher trr increases switching loss in >300 kHz designs; less efficient thermal coupling to PCB | Select PU6BC when board-level thermal management is critical and trr <30 ns is required |
| ON Semiconductor MUR620CT | 200 V VRRM, dual common-cathode configuration; not single-diode; trr = 35 ns | Requires redesign for single-diode layout; over-spec'd VRRM adds cost and capacitance | PU6BC offers better cost/performance fit for 100 V systems needing single-die simplicity and faster recovery |
Compared with VS-6EWH01-M3/45 and MUR620CT, the PU6BC delivers superior thermal performance (RθJL = 12 °C/W), tighter trr control (≤25 ns), and optimized single-die DO-214AB footprint-making it preferred for space-constrained, high-efficiency 100 V rectification where layout simplicity and thermal headroom matter.

FAQ
What is the maximum junction temperature rating for PU6BC?
The PU6BC has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table in the official TSC datasheet revision A2210. This allows reliable operation in sealed industrial enclosures or high-ambient environments without forced cooling. The PU6BC maintains specified electrical parameters up to this limit when thermal design adheres to RθJL = 12 °C/W on 16 mm × 16 mm Cu pads.
Does PU6BC have a halogen-free construction?
Yes, the PU6BC is halogen-free in accordance with IEC 61249-2-21 and RoHS-compliant, as confirmed in the "Features" section of the TSC datasheet A2210. The molding compound contains no brominated flame retardants or chlorine-based additives, supporting environmental compliance for export and green manufacturing programs. This applies specifically to the PU6BC, not just the PU6DC variant.
What is the reverse recovery time (trr) specification for PU6BC?
The PU6BC reverse recovery time is specified as ≤25 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table in the A2210 datasheet. An alternate condition (IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V) yields 31 ns - both values are guaranteed maximums. This trr enables clean switching in hard-switched topologies above 500 kHz.
Is PU6BC suitable for automated SMT assembly?
Yes, the PU6BC is explicitly designed for automated placement, as stated in its features list. It meets J-STD-020 moisture sensitivity level 1, has matte tin-plated leads compliant with J-STD-002 solderability, and uses the standardized DO-214AB (SMC) outline. These attributes ensure compatibility with high-speed pick-and-place machines and reflow profiles without popcorn or delamination risk - a key advantage of the PU6BC in volume production.
What is the marking code printed on the PU6BC device body?
The marking code physically laser-etched or printed on the PU6BC device body is "PU6BC", as confirmed in the Absolute Maximum Ratings table of the TSC datasheet A2210. This distinguishes it from the 200 V variant PU6DC and ensures traceability during inspection and assembly. No additional date or factory codes are part of the base marking for the PU6BC ordering code itself.
