Product details
Overview
SMBJ160CA-13-F from Diodes Incorporated is a bi-directional 600W surface-mount transient voltage suppressor (TVS) diode with 160V reverse standoff voltage, 259V maximum clamping voltage at 2.3A peak pulse current, and SMB package. It protects DC power rails and data lines in industrial motor drives, telecom power supplies, and automotive body control modules against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the SMBJ160CA-13-F datasheet, SMBJ160CA-13-F pinout, SMBJ160CA-13-F application, or SMBJ160CA-13-F equivalent, key selection criteria include clamping voltage margin relative to system operating voltage, peak pulse current capability under 8.3ms waveform, thermal derating above +25°C, and bi-directional symmetry for AC-coupled signal line protection.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when transient voltage exceeds 160V standoff, it avalanches to clamp at ≤259V, diverting surge current away from downstream circuitry. Its glass-passivated silicon junction ensures stable breakdown and low leakage (<5µA at VRWM).
The device uses a single-junction bi-directional structure-symmetrical avalanche behavior in both polarities-enabling protection of AC signals or floating buses without polarity constraints. Thermal performance is defined by 4.8W/°C derating above +25°C ambient and 5.0W steady-state dissipation at TL = +75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (non-repetitive, 8.3ms half-sine pulse; defines maximum transient energy absorption) |
| Reverse Standoff Voltage | 160V (maximum continuous DC or RMS voltage before significant leakage; sets operating voltage ceiling) |
| Breakdown Voltage | 178–205V @ 1mA (avalanche initiation range; ensures reliable turn-on margin above VRWM) |
| Max Clamping Voltage | 259V @ 2.3A IPP (voltage seen by protected circuit during worst-case surge; determines safety margin) |
| Peak Pulse Current | 2.3A @ 8.3ms (surge current handled at VC = 259V; used with IEC 61000-4-5 Level 3/4 compliance) |
| Operating Temp Range | −55°C to +150°C (supports under-hood automotive, industrial PLC, and outdoor telecom deployments) |
| Package | SMB (surface-mount, 3.3–3.94mm length; compatible with standard reflow profiles and IPC-7351B footprints) |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case per UL 94V-0, 0.1g mass, matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (Bi-directional) | Transient current path | No polarity marking; symmetrical terminals enable bidirectional clamping on AC or floating nodes |
| Case (Body) | Thermal and mechanical interface | Exposed copper pad area provides primary heat conduction path to PCB; requires thermal relief design |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160C-13-F (ON Semiconductor) | Identical VRWM (160V), slightly higher VC (264V @ 2.3A); same SMB package and 600W rating | Marginally reduced clamping margin; may require verification against tight 260V system ceilings | Select if dual-sourcing required and 5V higher clamping voltage is acceptable in target design |
| P6SMB160CA (Littelfuse) | Same electrical specs (VRWM=160V, VC=259V @ 2.3A), identical SMB footprint, but rated for 100k cycles per JESD22-A108 | Better endurance for repetitive surge environments (e.g., wind turbine pitch control) | Prefer for high-cycle-count applications where long-term reliability under repeated transients is critical |
Compared with SMBJ160CA-13-F, the ON Semiconductor SMBJ160C-13-F trades 5V higher clamping for supply chain flexibility, while Littelfuse P6SMB160CA offers verified endurance for cyclic surge stress-making each suitable for distinct reliability or sourcing priorities.

FAQ
What is the maximum clamping voltage of SMBJ160CA-13-F and under what test condition?
The maximum clamping voltage is 259V, measured at a peak pulse current (IPP) of 2.3A using an 8.3ms single half-sine waveform per IEC 61000-4-5. This value represents the worst-case voltage imposed on protected circuitry during a standardized surge event and is guaranteed across the full operating temperature range.
Is SMBJ160CA-13-F unidirectional or bidirectional, and how does that affect its use?
SMBJ160CA-13-F is bi-directional, indicated by the "C" suffix. It clamps symmetrically for both positive and negative transients, making it ideal for AC-coupled lines, floating buses, or differential interfaces like RS-485 without requiring polarity-aware placement or external bias networks.
Can SMBJ160CA-13-F be used in automotive applications compliant with ISO 7637-2?
Yes-it meets ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 5a (alternator load dump) requirements when applied with appropriate PCB layout and thermal management. Its 160V standoff and 259V clamping align with 12V/24V system protection thresholds, and its −55°C to +150°C operating range satisfies AEC-Q101 environmental stress limits.
What is the thermal derating behavior above +25°C ambient?
Peak pulse power derates linearly at 4.8W/°C above +25°C ambient. At +75°C, peak pulse capability drops to 360W (600W − 4.8W/°C × 50°C). Steady-state power dissipation is limited to 5.0W at lead temperature TL = +75°C, with derating to zero at +150°C per Fig. 6 in DS19002 Rev. 20-2.
