Product details

Overview

PE1BA from Taiwan Semiconductor is a 1A, 100V ultra-fast surface-mount rectifier diode in DO-214AC (SMA) package, featuring 15ns reverse recovery time, 0.85V forward voltage at 1A/25°C, and 30A surge current capability. It serves as a high-efficiency freewheeling or snubber diode in DC/DC converters operating up to several hundred kHz.

For engineers reviewing the PE1BA datasheet, PE1BA pinout, PE1BA application, or PE1BA equivalent, key selection criteria include its 100V V_RRM, ultra-fast trr ≤15ns, low R_θJA of 71°C/W on standard PCB, and RoHS/halogen-free compliance for industrial power conversion designs.

Technical Context

The PE1BA employs planar silicon technology optimized for fast switching with low Q_rr (10.5nC) and minimal stored charge, enabling reduced switching losses in hard-switched topologies. Its single-die configuration and cathode-band polarity marking support automated placement and unambiguous orientation on PCBs.

Thermal performance is characterized by R_θJL = 22°C/W and R_θJC = 22°C/W, indicating efficient heat conduction from junction to lead or case-critical for sustained 1A operation at T_J up to +175°C in compact power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for DC bus or snubber voltage rating
I_F	1 A - Continuous average forward current at T_A = 25°C; derates linearly above 25°C per Fig.1
t_rr	≤15 ns - Measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables high-frequency operation with low switching loss
V_F	0.85 V @ 1A/25°C - Forward drop directly impacts conduction loss and thermal load in output rectification
Q_rr	10.5 nC - Reverse recovery charge determines turn-off energy loss and EMI generation in switching nodes
R_θJA	71 °C/W - Junction-to-ambient thermal resistance on 5mm × 5mm Cu pad; defines required heatsinking for thermal design

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06	V_RRM = 600V, t_rr = 25ns, V_F = 1.15V @ 1A - higher voltage rating but slower and higher loss	Suitable for 400V PFC front-ends; not optimal for 100V snubbers due to excessive V_F and trr	Select PE1BA when V_RRM ≤100V and t_rr < 20ns is required for EMI-sensitive layouts
MBR1100	V_RRM = 100V, t_rr = 35ns, V_F = 0.82V @ 1A - Schottky architecture, no reverse recovery but limited to 125°C max T_J	Better for low-V_F priority below 125°C; unsuitable for 175°C ambient or high-di/dt snubbers	Choose PE1BA over MBR1100 when junction temperature exceeds 125°C or di/dt >100A/µs demands true ultra-fast recovery

Compared with STTH1R06 and MBR1100, the PE1BA uniquely balances 100V V_RRM, 15ns t_rr, 175°C T_J rating, and 0.85V V_F-making it the preferred choice for compact, high-temperature, high-frequency rectification where both speed and thermal robustness are critical.

FAQ

What is the maximum junction temperature rating for the PE1BA?

The PE1BA has a maximum junction temperature (T_J) rating of +175°C, verified per absolute maximum ratings table. This allows reliable operation in high-ambient environments such as enclosed industrial power supplies or under-hood automotive modules. Derating curves in the datasheet confirm usable current capacity down to −55°C storage temperature. The PE1BA maintains specified electrical parameters within this full range when mounted per JEDEC DO-214AC thermal test conditions.

Does the PE1BA have a specified reverse recovery time (t_rr)?

Yes, the PE1BA specifies t_rr ≤15ns under test conditions of I_F = 0.5A, I_R = 1.0A, and I_rr = 0.25A. An alternate condition (I_F = 1.0A, di/dt = 50A/µs, V_R = 30V) yields t_rr ≤23ns. These values are measured and guaranteed per the A2301 revision datasheet, confirming its classification as an ultra-fast rectifier suitable for >200kHz switching applications.

What is the forward voltage (V_F) of the PE1BA at 1A and 25°C?

The PE1BA exhibits a typical forward voltage of 0.85V at I_F = 1.0A and T_J = 25°C, with a maximum of 0.92V under the same conditions. At elevated temperature (T_J = 125°C), V_F drops to 0.69V typical, reflecting the negative temperature coefficient of silicon PN junctions. This V_F directly determines conduction loss in the PE1BA's intended applications.

Is the PE1BA RoHS and halogen-free compliant?

Yes, the PE1BA is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the features section of the A2301 datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 solderability standards. These compliance attributes are certified for the PE1BA and documented in TSC's material declarations.

What package type does the PE1BA use, and what are its key mechanical properties?

The PE1BA uses the DO-214AC (SMA) surface-mount package, with dimensions per JEDEC DO-214 Variation AC. Key mechanical properties include UL 94V-0 flammability rating, JESD201 Class 2 whisker resistance, moisture sensitivity level 1, and 0.060g mass. The cathode is marked by a visible band, and leads are matte tin plated for compatibility with standard reflow profiles-no pre-baking required.
