Product details
Overview
PUUP8DH from Taiwan Semiconductor is a 200V, 8A ultra-fast surface-mount rectifier in TO-277A (SMPC4.6U) package, featuring 25 ns reverse recovery time, 0.88 V forward voltage at 8A/25°C, and AEC-Q101 qualification for automotive-grade reliability in high-frequency DC/DC converters and snubber circuits.
For engineers reviewing the PUUP8DH datasheet, PUUP8DH pinout, PUUP8DH application, or PUUP8DH equivalent, key selection criteria include its 200V repetitive peak reverse voltage, wettable flank leads for solder inspection, 175°C maximum junction temperature, and compatibility with automated SMT placement on industrial and automotive power supplies.
Technical Context
This single-die ultra-fast rectifier uses planar technology to achieve low forward voltage drop and minimal reverse recovery charge (89 nC), enabling high-efficiency operation in switching frequencies up to several hundred kHz. Its 2.0°C/W junction-to-lead thermal resistance supports high-current conduction with minimal thermal derating when mounted on copper pads.
The device exhibits temperature-stable reverse leakage (≤15 µA at 125°C) and maintains fast trr of 31 ns under 8A di/dt = 200A/µs conditions, making it suitable for hard-switched topologies where switching loss minimization is critical.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-8EWH02FN-M3 | 200V VRRM, 8A IF, but TO-220AC package (through-hole); trr = 35 ns, VF = 0.92 V @ 8A | Requires PCB through-hole mounting and larger footprint; not suitable for high-density SMT designs | Select when legacy board design or mechanical retention mandates through-hole packaging |
| ON Semiconductor MUR820G | 200V VRRM, 8A IF, TO-220AC package; trr = 35 ns, VF = 0.975 V @ 8A; no AEC-Q101 or wettable flank | Lacks automotive qualification and AOI-compatible leads; lower thermal performance (RθJA = 50°C/W) | Acceptable for cost-sensitive industrial power supplies where AEC-Q101 and optical inspection are not required |

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for PUUP8DH?
The PUUP8DH has a VRRM of 200 V, verified per Taiwan Semiconductor's A2111 datasheet. This rating ensures reliable reverse blocking in 200V-class power rails, such as 48V automotive systems and industrial 200V DC buses. Exceeding this voltage risks avalanche breakdown and permanent device failure.
Is PUUP8DH qualified for automotive applications?
Yes, PUUP8DH is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and ESD. This certification confirms its suitability for under-hood and chassis-mounted automotive power electronics.
What is the reverse recovery time (trr) of PUUP8DH under typical operating conditions?
The PUUP8DH exhibits a trr of 31 ns when tested at IF = 8.0A, di/dt = 200A/µs, and VR = 100V. This value is confirmed in the Electrical Specifications table of the official datasheet and reflects real-world performance in hard-switched converters operating above 200 kHz.
Does PUUP8DH have wettable flank leads, and why does it matter?
Yes, PUUP8DH features wettable flank leads per its mechanical data. This design enables automated optical inspection (AOI) of solder fillets on side surfaces, improving manufacturing yield and field reliability-especially critical in automotive and telecom production where zero-defect assembly is mandated.
What is the junction-to-lead thermal resistance (RθJL) of PUUP8DH, and how is it used in thermal design?
PUUP8DH has an RθJL of 2.0°C/W with ideal heatsink conditions. Engineers use this value to calculate junction temperature rise above lead temperature (ΔTJL = RθJL × PD), supporting thermal modeling when the device is soldered directly to thick copper planes or thermal pads in high-power layouts.
