Product details
Overview
PE1BAH from Taiwan Semiconductor is a 1 A, 100 V ultra-fast surface-mount rectifier diode in DO-214AC (SMA) package, featuring 15 ns reverse recovery time, 0.85 V forward voltage at 1.0 A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-frequency switching diode in DC/DC converters and snubber circuits.
For engineers reviewing the PE1BAH datasheet, PE1BAH pinout, PE1BAH application, or PE1BAH equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 30 A surge current rating, junction-to-lead thermal resistance of 22 °C/W, and moisture sensitivity level 1 compliance - all critical for high-reliability power conversion designs.
Technical Context
This single-die planar silicon rectifier operates with ultra-fast recovery (trr ≤ 15 ns under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A), low forward voltage drop (VF = 0.85 V max at 1.0 A/25°C), and high junction temperature capability (TJ up to +175°C). Its DO-214AC (SMA) package supports automated placement and meets JESD201 Class 2 whisker resistance.
The device delivers 24 pF junction capacitance at 1 MHz/4.0 V and reverse recovery charge (Qrr) of 10.5 nC, enabling efficient operation in high-frequency switching topologies where switching loss minimization is essential. Thermal performance is characterized with RθJA = 71 °C/W on a 5 mm × 5 mm Cu pad PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or snubber applications |
| IF | 1 A continuous - average forward current rating at TA = 25°C; determines steady-state power handling capacity |
| IFSM | 30 A (8.3 ms) - non-repetitive surge current; enables robustness against transient overloads in DC/DC input stages |
| trr | 15 ns max - ultra-fast reverse recovery; reduces switching losses and EMI in >100 kHz converters |
| VF | 0.85 V max at 1.0 A/25°C - low conduction loss; improves system efficiency and thermal margin |
| RθJL | 22 °C/W - junction-to-lead thermal resistance; supports direct heat transfer to PCB copper for compact layouts |
| Qrr | 10.5 nC - reverse recovery charge; directly impacts turn-off loss and gate drive requirements in synchronous designs |

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 | Same 1 A / 600 V rating but higher VF (1.15 V typ), slower trr (35 ns), and no AEC-Q101 qualification | More suitable for general-purpose industrial AC-DC where voltage margin >600 V is required | Choose STTH1R06 only if higher VRRM is mandatory and automotive qualification is unnecessary |
| MBR1100 | 1 A / 100 V Schottky diode with VF = 0.82 V typ but limited TJ max = 125°C and no AEC-Q101 | Better efficiency at low voltage but unsuitable for high-temperature or automotive underhood use | Select MBR1100 only for cost-sensitive consumer adapters with ambient <85°C |
Compared with STTH1R06 and MBR1100, PE1BAH uniquely combines AEC-Q101 qualification, 175°C junction rating, and 15 ns trr - making it the only option among the three validated for automotive-grade high-frequency rectification with thermal resilience.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for PE1BAH?
The PE1BAH has a VRRM of 100 V, meaning it can reliably block up to 100 V of reverse voltage in repetitive operation. This rating is confirmed in the Absolute Maximum Ratings table and applies specifically to the PE1BAH variant - distinct from PE1DAH (200 V). Exceeding this voltage risks avalanche breakdown and permanent damage to the PE1BAH.
Is PE1BAH suitable for automotive applications?
Yes, PE1BAH is AEC-Q101 qualified and rated for junction temperatures from –55°C to +175°C, making it suitable for underhood automotive power supplies, body control modules, and ADAS subsystems. Its DO-214AC (SMA) package, moisture sensitivity level 1, and JESD201 Class 2 whisker resistance further support automotive manufacturing and field reliability requirements for the PE1BAH.
What is the forward voltage (VF) of PE1BAH at 1.0 A and 25°C?
The PE1BAH exhibits a maximum forward voltage of 0.92 V at 1.0 A and 25°C, with a typical value of 0.85 V under the same conditions. This low VF contributes to reduced conduction losses in high-current, high-duty-cycle applications - a key parameter verified in the Electrical Specifications table for the PE1BAH.
Does PE1BAH have a defined reverse recovery time (trr)?
Yes, PE1BAH has a specified reverse recovery time of ≤15 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. An alternate condition (IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V) yields trr ≤ 23 ns. These values confirm the PE1BAH's classification as an ultra-fast rectifier optimized for high-frequency switching.
What package type does PE1BAH use, and what are its key mechanical features?
PE1BAH uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads, UL 94V-0 molding compound, and cathode band polarity marking. Its mechanical outline conforms to JEDEC DO-214AC, and it weighs approximately 0.060 g. The PE1BAH's package supports automated placement and reflow soldering per J-STD-002, with thermal performance characterized on a 5 mm × 5 mm Cu pad PCB.
