Product details
Overview
BAT54L from Nexperia is a planar Schottky barrier diode in a leadless DFN1006-2 (SOD882) package, designed for ultra-high-speed switching and voltage clamping. It delivers 30 V reverse voltage rating, 200 mA continuous forward current, 800 mV forward voltage at 100 mA, 10 pF capacitance at 1 V, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BAT54L datasheet, BAT54L pinout, BAT54L application, or BAT54L equivalent, key selection criteria include low VF for power-sensitive portable devices, ultra-small 1.17 mm² footprint for space-constrained PCBs, and pulsed reverse leakage stability under transient conditions in protection circuits.
Technical Context
The BAT54L employs a planar Schottky junction structure optimized for fast recovery (trr < 5 ns, inferred from Schottky physics and typical application context), enabling operation in high-frequency switching up to ~100 MHz. Its low-barrier metal-semiconductor interface yields minimal stored charge and negligible minority-carrier tail current.
Thermal performance is defined by Rth(j-a) = 500 K/W on FR4 with single-sided copper, supporting 250 mW total power dissipation at 25 °C ambient. Junction temperature is rated to 150 °C, with storage and operating range spanning −65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum DC or repetitive peak reverse bias before breakdown; sets clamping headroom in ESD/overvoltage protection. |
| Forward Current (IF) | 200 mA - Continuous DC current handling; supports signal-level rectification and rail steering in compact logic interfaces. |
| Forward Voltage (VF) | 800 mV @ 100 mA - Low conduction loss enables efficient voltage translation and low-drop OR-ing in dual-power systems. |
| Diode Capacitance (Cd) | 10 pF @ 1 V - Enables RF bypass and high-speed signal routing without excessive loading on GHz-range traces. |
| Reverse Leakage (IR) | 2 µA @ 25 V - Stable leakage under pulsed stress ensures reliable clamping margin in transient suppression circuits. |
| Package Size | 1.0 mm × 0.6 mm × 0.5 mm - Ultra-compact DFN1006-2 footprint reduces board area by ~90% vs SOT23, critical for mobile camera modules and PCMCIA cards. |
Pinout & Package
Encapsulated in a leadless DFN1006-2 (SOD882) package with exposed thermal pad not electrically connected; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output node for clamping and rectification; polarity reference for directional current flow and ESD path orientation. |
| 2 | Anode (A) | Input node for forward conduction; connects to protected line or supply rail in series or shunt configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Low Forward Voltage | 800 mV at 100 mA - Reduces conduction loss in battery-powered signal paths and improves efficiency in level-shifting networks. |
| Ultra-Small Footprint | 1.17 mm² board area - Enables placement adjacent to high-density BGA ICs and within tight camera module flex PCB zones. |
| AEC-Q101 Qualification | Qualified for automotive-grade reliability - Validated for temperature cycling, HTRB, and ESD per AEC-Q101, supporting infotainment and ADAS subsystems. |
| Thermal Performance | Rth(j-a) = 500 K/W on standard FR4 - Allows sustained 200 mA operation without forced cooling in handheld device enclosures. |
Applications
| Mobile Camera Power Sequencing | Digital Camera ESD Protection |
|---|---|
Use Scenario: Managing power-up sequencing between image sensor and ISP in compact digital still cameras. IC Role / Device Role / Timing Role: Schottky diode used in OR-ing configuration to isolate dual supplies and prevent backfeed during state transitions. Use Value: 800 mV VF minimizes voltage drop across diode, preserving headroom for 1.8 V sensor rails while maintaining 200 mA peak current capability. | Use Scenario: Protecting high-speed data lines (e.g., MIPI CSI-2) from ESD transients in smartphone camera modules. IC Role / Device Role / Timing Role: Low-capacitance (10 pF) shunt diode clamping I/O pins to ground or VCC during ±8 kV contact discharge events. Use Value: 10 pF capacitance avoids signal integrity degradation on >100 MHz differential pairs, meeting USB-IF and MIPI timing budgets. |
| PCMCIA Card Voltage Clamping | Automotive Infotainment USB Port Protection |
Use Scenario: Preventing overvoltage damage during hot-plug insertion of PCMCIA memory or modem cards into laptops. IC Role / Device Role / Timing Role: Bidirectional clamping diode pair (with BAT54C variant) limiting VBUS excursions to ±30 V. Use Value: 30 V VR rating provides 2× safety margin above 12 V PCMCIA bus, while low IR ensures stable clamp threshold under repeated surges. | Use Scenario: Safeguarding USB 2.0 data lines in automotive head units against load-dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: AEC-Q101-qualified Schottky diode integrated into TVS-assisted protection network on D+/D− lines. Use Value: AEC-Q101 qualification guarantees operation across −40 °C to +125 °C ambient, matching vehicle cabin thermal profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Same DFN1006-2 package; VF = 450 mV @ 100 mA (lower), VR = 30 V, Cd = 12 pF. | Slightly higher capacitance may affect >500 MHz RF lines; lower VF benefits ultra-low-power wearables. | Select when lower forward drop outweighs marginal capacitance increase in sub-1 V logic interfaces. |
| Vishay VS-2EDH01HM3/H | DO-219AB package (larger); VF = 510 mV @ 100 mA; VR = 30 V; AEC-Q101 qualified. | Not footprint-compatible; requires PCB redesign but offers better thermal dissipation (Rth(j-a) ≈ 300 K/W). | Choose for higher-reliability industrial control where board space allows and thermal margin is critical. |
Compared with NSR0230HT1G and VS-2EDH01HM3/H, the BAT54L balances ultra-compact size, automotive qualification, and predictable 10 pF capacitance-making it optimal for space-constrained, high-frequency mobile and automotive signal-line protection where layout density is prioritized over marginal VF reduction or thermal headroom.

FAQ
What is the maximum junction temperature for BAT54L during continuous operation?
The BAT54L has a maximum junction temperature (Tj) rating of 150 °C. This limit applies under steady-state conditions with ambient temperature ≤25 °C and PCB layout meeting the specified FR4 single-sided copper footprint. Exceeding this temperature risks permanent parametric shift or metallurgical failure.
Is BAT54L suitable for bidirectional ESD protection without additional components?
No. The BAT54L is a single anode–cathode Schottky diode and provides unidirectional clamping only. For bidirectional protection (e.g., USB D+ and D− lines), two BAT54L devices must be configured in series-opposed orientation, or a dedicated dual-channel TVS like PESD5V0S1BA should be used.
Does the cathode marking on BAT54L align with industry-standard DFN1006-2 pin 1 orientation?
Yes. Per Nexperia's package outline (Fig. 4), the cathode marking bar is located adjacent to pin 1 (cathode) on the top surface, consistent with JEDEC MO-229 and IPC-7351 standards for DFN1006-2. Pin 2 (anode) is diagonally opposite, confirmed by transparent top-view graphic symbol in Table 2.
Can BAT54L replace BAT54 in existing SOT23 designs without layout changes?
No. BAT54L uses the DFN1006-2 (SOD882) package (1.0 mm × 0.6 mm), whereas BAT54 uses SOT23 (2.9 mm × 1.3 mm). Direct replacement requires full PCB redesign, including new solder paste stencil, reflow profile validation, and thermal simulation due to differing Rth(j-a) and mounting constraints.
