Product details
Overview
BAT54JW-7 from Diodes Incorporated is a dual-channel surface-mount Schottky barrier diode array in SOT-363 package, featuring 30 V peak reverse voltage, 200 mA continuous forward current, and ultra-low 240–500 mV forward voltage at 0.1–100 mA. It integrates two independent Schottky diodes with PN junction guard ring for ESD/transient protection, used in polarity protection and signal clamping in portable power management circuits.
For engineers reviewing the BAT54JW-7 datasheet, BAT54JW-7 pinout, BAT54JW-7 application, or BAT54JW-7 equivalent, key selection criteria include low VF at low currents, fast 5.0 ns reverse recovery time, 10 pF junction capacitance at 1 V, thermal resistance of 625 °C/W, and RoHS-compliant lead-free plating on Alloy 42 leadframe.
Technical Context
The BAT54JW-7 implements two independent Schottky diodes sharing no internal connection except jumper between middle pins (A2–C2), enabling flexible dual-anode or dual-cathode configurations. Its guard-ringed PN junction suppresses transient-induced latch-up and meets IEC 61000-4-2 ESD immunity requirements without external components.
Designed for high-frequency switching up to ~100 MHz, it delivers stable conduction under pulsed IF = 300 mA (IFRM) and withstands 600 mA non-repetitive surge (IFSM). Thermal derating begins at 25 °C ambient, with full 200 mW power dissipation only below 25 °C per Fig. 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; defines safe DC blocking range in bias networks. |
| VF @ 10 mA | 320 mV - Low forward drop ensures minimal power loss in battery-fed 3.3 V logic rail clamping. |
| trr | 5.0 ns - Enables clean signal edge preservation in USB 1.1/2.0 data line protection. |
| CT @ 1 V | 10 pF - Low junction capacitance avoids signal integrity degradation in RF detector inputs. |
| RθJA | 625 °C/W - Requires minimum 25 mm² copper pour for sustained 200 mW operation at TA = 70 °C. |
| IR @ 25 V | 2.0 μA - Leakage level suitable for precision analog front-end biasing without offset drift. |

IC Role / Device Role / Timing Role: Low-leakage (2 μA IR) DC blocking diode isolating detector output from bias supply. Use Value: 2.0 μA IR at 25 V prevents detector output offset shift across −40 to +85 °C operating range. |

FAQ
What is the maximum continuous forward current rating for BAT54JW-7?
The BAT54JW-7 is rated for 200 mA continuous forward current (IF) at TA = 25 °C with recommended FR-4 pad layout. Derating is required above 25 °C ambient per Fig. 4: power dissipation drops linearly to zero at 125 °C junction temperature.
Does BAT54JW-7 have internal connections between its diodes?
Yes - Pins 2 (A2) and 4 (C2) are internally jumpered, forming a common-cathode configuration for Diode 2. Pins 1 (C1) and 3 (A1) are independent cathode/anode terminals for Diode 1. Pins 5 and 6 are unconnected.
Can BAT54JW-7 replace BAT54C in the same PCB footprint?
No - BAT54C uses SOT-23 package (3-pin) with common-cathode configuration, while BAT54JW-7 uses SOT-363 (6-pin) with different pinout and internal jumpering. Pad layout, stencil design, and reflow profile must be redesigned.
Is BAT54JW-7 suitable for 5 V logic-level clamping?
Yes - with VF ≤ 400 mV at 30 mA and IR ≤ 2.0 μA at 25 V, it clamps 5 V signals to ~5.4 V (VDD + VF) and −0.25 V (GND − VF), staying within standard 5 V TTL/CMOS input voltage limits while adding ESD robustness.
