Product details
Overview
BAT54H,115 from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in a compact SOD123F surface-mount package. It delivers 30 V reverse voltage rating, 200 mA continuous forward current, 400 mV typical forward voltage at 10 mA, 10 pF capacitance at 1 V, and supports ultra-high-speed switching in portable power management circuits.
For engineers reviewing the BAT54H,115 datasheet, BAT54H,115 pinout, BAT54H,115 application, or BAT54H,115 equivalent, key selection criteria include low VF for efficiency-critical clamping, low Cd for high-frequency line termination, thermal resistance (Rth(j-a) = 330 K/W), and SOD123F footprint compatibility with space-constrained PCB layouts.
Technical Context
The BAT54H,115 implements a planar Schottky junction with an integrated guard ring to enhance ESD and transient robustness without compromising switching speed. Its low-barrier metal-semiconductor interface enables fast recovery (no minority-carrier storage) and sub-1 ns reverse recovery time.
Designed for operation up to 125 °C junction temperature, it maintains stable VF and IR across ambient temperatures from −65 °C to +125 °C, with thermal resistance from junction to solder point (Rth(j-sp)) specified at 70 K/W - critical for thermal design in densely packed DC-DC converter outputs and USB port protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 30 V - defines maximum allowable blocking voltage before breakdown; suitable for 24 V rail clamping and 5 V/3.3 V bus protection. |
| IF (Forward Current) | 200 mA continuous - supports sustained current in low-power signal path protection and biasing networks. |
| VF (Forward Voltage) | 400 mV @ 10 mA - minimizes conduction loss in polarity-reversal protection and OR-ing diodes. |
| Cd (Diode Capacitance) | 10 pF @ 1 V, 1 MHz - enables clean signal integrity in >100 MHz data line termination and RF detector applications. |
| IR (Reverse Current) | 2 µA @ 25 V, 25 °C - ensures low leakage in battery-backed circuits and high-impedance sensing nodes. |
| Rth(j-a) (Junction-to-Ambient) | 330 K/W - determines self-heating under free-air conditions; requires thermal relief pads for >100 mA steady-state use. |
Pinout & Package
Encapsulated in the SOD123F plastic SMD package (2.6 mm × 1.6 mm × 1.1 mm body), the BAT54H,115 features a flat lead profile optimized for automated placement and reflow soldering on FR4 PCBs with standard footprint per Figure 5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Marked side with bar; connects to lower-potential node in clamping, reverse-polarity, or OR-ing configurations. |
| 2 | Anode (A) | Unmarked terminal; ties to input source or higher-potential rail; forms forward-biased path when A > K. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD robustness (IEC 61000-4-2 level 4) and improves surge tolerance without increasing VF or Cd. |
| Low forward voltage | 400 mV typ. @ 10 mA enables <10 mW conduction loss in 3.3 V supply rails - critical for battery runtime extension. |
| Low junction capacitance | 10 pF @ 1 V allows use in 100+ MHz signal lines (e.g., USB 2.0 D+/D−, LVDS, CAN FD stubs) without signal degradation. |
| SOD123F footprint | 2.6 mm × 1.6 mm outline fits tight pitch layouts; compatible with IPC-7351B SOIC-2 land pattern variants. |
Applications
| Ultra-High-Speed Switching | Voltage Clamping |
|---|---|
Use Scenario: Fast edge-rate digital signals (e.g., clock distribution, FPGA I/O) require sub-nanosecond response to suppress overshoot. IC Role / Device Role / Timing Role: Schottky clamp diode placed between signal line and VCC/GND to shunt transient energy. Use Value: 10 pF capacitance and <1 ns recovery prevent ringing while 400 mV VF limits clamping threshold below logic overvoltage limits. |
Use Scenario: Protecting microcontroller GPIO pins from inductive kickback in relay or solenoid drive circuits. IC Role / Device Role / Timing Role: Reverse-biased flyback diode across inductive load to absorb stored energy during turn-off. Use Value: 30 V VR rating safely handles 24 V coil transients; 200 mA IF sustains repeated switching at 10 Hz–1 kHz duty cycles. |
| Line Termination | Inverse-Polarity Protection |
Use Scenario: Matching impedance on high-speed serial buses (e.g., RS-485 stubs, MIPI D-PHY) to minimize reflections. IC Role / Device Role / Timing Role: AC-coupled termination diode providing dynamic impedance control via low Cd and controlled VF. Use Value: 10 pF capacitance ensures minimal phase shift up to 200 MHz; low VF avoids DC bias shift in bidirectional lines. |
Use Scenario: Preventing damage to USB-C or barrel-jack powered devices when external adapter is inserted backward. IC Role / Device Role / Timing Role: Series anode-to-load configuration that blocks reverse current while passing forward current with minimal drop. Use Value: 400 mV VF adds only 0.4% loss on a 3.3 V rail; 2 µA IR prevents battery drain in always-on systems. |
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 NSS40201MR6T1G | Higher VF (500 mV @ 10 mA); same SOD-123 package; 40 V VR rating. | Better suited for 36 V industrial inputs but increases conduction loss in 3.3 V systems. | Select when higher reverse voltage margin is required and 100 mV VF penalty is acceptable. |
| Diodes Incorporated BAV99LT1G | Double diode array in SOT-23; VF = 1.25 V @ 50 mA; 70 V VR; no guard ring. | Offers dual-channel functionality but higher VF and larger footprint; lacks stress protection. | Choose only if dual-diode topology is mandatory and thermal/ESD robustness is secondary. |
Compared with NSS40201MR6T1G and BAV99LT1G, the BAT54H,115 provides the lowest VF and integrated guard ring in the smallest single-diode SOD123F form factor - making it optimal for space- and efficiency-constrained 3.3 V/5 V portable designs where reliability under electrical stress is critical.

FAQ
What is the maximum junction temperature for BAT54H,115?
The absolute maximum junction temperature is 125 °C, validated per IEC 60134 limiting values. Operation above this temperature risks permanent parametric shift or failure. Derating is required above 75 °C ambient when dissipating >100 mW, based on Rth(j-a) = 330 K/W.
Does BAT54H,115 have automotive qualification?
No. Per the October 2024 revision history, BAT54H,115 was explicitly changed to non-automotive status. It is not qualified to AEC-Q101 and lacks automotive-specific testing, traceability, or PPAP documentation. Use automotive-grade alternatives like BAT54HW,115-Q for vehicle applications.
How is cathode identification marked on BAT54H,115?
The cathode is identified by a marking bar on the device body, aligned with Pin 1 per Table 2. This bar corresponds to the cathode (K) terminal and must be oriented toward the lower-potential node in circuit layout - e.g., ground for clamping or VBUS for reverse-polarity protection.
Can BAT54H,115 replace BAT54C in existing designs?
Yes, with verification. Both share identical SOD123F package and pinout, but BAT54C has 30 V VR and 200 mA IF like BAT54H,115. However, BAT54H,115 adds the integrated guard ring for improved ESD robustness - beneficial in handheld or exposed-interface applications without requiring layout changes.
