Product details
Overview
BAT85,113 from Nexperia is a planar Schottky barrier single diode in a hermetically sealed DO-34 (SOD68) axial package, featuring guard ring stress protection. It delivers 400 mV forward voltage at 10 mA, 30 V reverse voltage rating, 4 ns reverse recovery time, and 10 pF junction capacitance at 1 V - optimized for ultra-high-speed switching in low-voltage signal path protection.
For engineers reviewing the BAT85,113 datasheet, BAT85,113 pinout, BAT85,113 application, or BAT85,113 equivalent, this diode is selected for precision clamping, high-frequency blocking, and ESD-sensitive interface protection where low VF, fast trr, and stable thermal performance across −65 °C to 125 °C are critical design requirements.
Technical Context
The BAT85,113 employs a planar Schottky junction with integrated guard ring to suppress edge breakdown under transient stress, enabling reliable operation in unprotected input stages. Its low 320 K/W junction-to-ambient thermal resistance (on FR4 PCB) supports sustained 200 mA average forward current at 25 °C ambient.
With 2 µA reverse leakage at 25 V and 25 °C, and sub-4 ns reverse recovery, it avoids minority-carrier storage delay - making it unsuitable for rectification above ~100 kHz but ideal for RF detector biasing, logic-level clamping, and fast polarity reversal circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 10 mA | 400 mV - enables minimal forward drop in 3.3 V/5 V logic clamping without loading source |
| VR | 30 V - sets maximum allowable reverse standoff in low-voltage I/O protection |
| trr | 4 ns - ensures negligible switching delay in >100 MHz signal routing and sampling circuits |
| Cd @ 1 V | 10 pF - maintains high impedance above 100 MHz, preserving signal integrity in RF paths |
| IF(AV) | 200 mA - supports continuous current in power rail decoupling and active bias networks |
| IR @ 25 V | 2 µA - guarantees low leakage in high-impedance sensing nodes and battery-backed circuits |
Pinout & Package
Encapsulated in a hermetically sealed DO-34 (SOD68) axial-leaded glass package with 5.08 mm pitch compatibility. Leads are tin-plated, and the body diameter is ≤1.6 mm with overall length ≤3.04 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked band) | Cathode (K) | Negative terminal; connects to reference or return path in clamping and protection configurations |
| 2 | Anode (A) | Positive terminal; ties to signal source or supply rail in forward-biased applications |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents premature edge breakdown under ESD or voltage transients, improving long-term reliability in unbuffered interfaces |
| Hermetically sealed glass package | Eliminates moisture ingress and parameter drift over time - critical for aerospace and industrial control environments |
| Low thermal resistance (320 K/W) | Enables direct PCB mounting without heatsinking for 200 mA DC operation on standard FR4 |
| Fast reverse recovery (4 ns) | Reduces switching loss and ringing in high-frequency AC coupling and pulse shaping networks |
Applications
| USB Interface Protection | RF Detector Biasing |
|---|---|
Use Scenario: Clamping D+ and D− lines to 3.3 V rail against ESD and overvoltage events in USB 2.0 host ports. IC Role / Device Role / Timing Role: Signal-level Schottky clamp diode providing bidirectional voltage limiting without affecting 480 Mbps data integrity. Use Value: 400 mV VF ensures <100 mV overshoot margin below 3.6 V absolute max for USB PHYs; 4 ns trr prevents data eye distortion. |
Use Scenario: Providing temperature-stable DC bias to GaAs FET detectors in 900 MHz ISM-band receivers. IC Role / Device Role / Timing Role: Low-capacitance anode-cathode path establishing fixed DC operating point while passing RF signals. Use Value: 10 pF Cd minimizes RF shunting; 2 µA IR avoids detector offset drift across −40 °C to 85 °C. |
| Logic-Level Clamping | Blocking Diode in Low-Power Sensors |
Use Scenario: Preventing negative voltage excursions on microcontroller GPIO pins during hot-swap or cable disconnect events. IC Role / Device Role / Timing Role: Cathode-to-rail configuration clamping inputs to safe levels during transient fault conditions. Use Value: Guard ring ensures consistent 30 V VR rating across manufacturing lot; 400 mV VF avoids false logic-low detection. |
Use Scenario: Isolating coin-cell backup supply from main 3.3 V rail in real-time clock modules to prevent backfeed. IC Role / Device Role / Timing Role: Anode-to-main-rail, cathode-to-RTC configuration enabling one-way current flow with minimal voltage loss. Use Value: 200 mA IF(AV) supports peak RTC load surges; 320 K/W Rth(j-a) allows operation without derating at 70 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5711 | Higher VF (450–600 mV @ 10 mA), larger DO-35 package (3.8 mm length), no guard ring | Less robust in ESD-prone environments; higher forward loss reduces margin in 3.3 V systems | Preferred only when legacy footprint compatibility outweighs leakage and ruggedness needs |
| SB130 | Higher IF(AV) = 1 A, VF ≈ 500 mV @ 100 mA, DO-41 package, slower trr (~10 ns) | Over-specified for signal-level use; excessive capacitance (≈30 pF) degrades RF performance | Select only for power rail OR-ing where speed is secondary to current handling |
Compared with 1N5711 and SB130, BAT85,113 offers superior combination of low VF, ultrafast trr, and guard ring protection in a compact DO-34 package - making it optimal for space-constrained, high-frequency signal integrity applications rather than power rectification or legacy replacement.

FAQ
Is BAT85,113 suitable for automotive applications?
No. BAT85,113 is not AEC-Q200 qualified and lacks automotive-specific testing or qualification. Nexperia explicitly states non-automotive status in its legal disclaimers. It is rated for −65 °C to 125 °C ambient but not validated for automotive vibration, extended temperature cycling, or PPAP compliance.
What is the meaning of the band marking on BAT85,113?
The black band on the DO-34 glass body identifies Pin 1 as the cathode (K). This matches the pinning table in the datasheet and is consistent with industry-standard diode marking convention - the banded end connects to the circuit reference or ground side in clamping configurations.
Can BAT85,113 replace BAT54 in SOT-23 packages?
No - BAT85,113 is DO-34 axial-leaded and not pin-compatible with surface-mount BAT54 variants. While both are Schottky diodes, BAT54 has higher VF (≈350–500 mV depending on variant), different thermal behavior, and dual/quad configurations unavailable in BAT85,113's single-diode form factor.
How does guard ring protection improve reliability?
The integrated guard ring redistributes electric field at the silicon periphery, suppressing edge-initiated avalanche and preventing localized hot spots during voltage transients. This extends operational life in unbuffered I/O circuits exposed to ESD or inductive kickback, as confirmed by Nexperia's stress-protection design intent in Section 1.1.
