Product details
Overview
SMAJ110CA-13-F from Diodes Incorporated is a bidirectional 400W transient voltage suppressor (TVS) diode in SMA package, designed for primary overvoltage protection of DC power rails and signal lines. It features 110V reverse standoff voltage (VRWM), 122–135V breakdown range (VBR), 177V maximum clamping voltage (VC) at 2.3A peak pulse current (IPP), and operates from –55°C to +150°C - used in automotive infotainment power inputs and industrial PLC I/O protection.
For engineers reviewing the SMAJ110CA-13-F datasheet, SMAJ110CA-13-F pinout, SMAJ110CA-13-F application, or SMAJ110CA-13-F equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, unidirectional vs. bidirectional polarity requirements, thermal derating above +25°C ambient, and compatibility with IPC-7351B SMA footprint land patterns.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling robust ESD and surge suppression on AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage (<5µA at VRWM) and repeatable clamping performance under repetitive transients.
The device responds within <1 ns to fast-rising transients (e.g., IEC 61000-4-2 contact discharge), clamping energy via avalanche breakdown while maintaining low dynamic impedance (~77 Ω, derived from ΔVC/ΔIPP). Thermal design must account for 1.0W steady-state dissipation at TL = +75°C and pulse derating per Fig. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W - sustains single 10/1000 µs waveform surges up to 400W without failure |
| Reverse Standoff Voltage | 110 V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage Range | 122–135 V - guaranteed avalanche initiation window at 1.0 mA test current |
| Clamping Voltage | 177 V @ 2.3 A - maximum voltage seen by protected circuit during specified 8.3 ms half-sine surge |
| Leakage Current | ≤5 µA @ 110 V - negligible standby power loss and minimal impact on high-impedance bias networks |
| Operating Temperature | –55°C to +150°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic case with UL 94V-0 rating; cathode band omitted (bidirectional configuration); weight ≈ 0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No polarity marking; terminals interchangeable - enables protection on AC or floating nodes |
| Case / Body | Thermal path and mechanical anchor | Exposed copper pad required for thermal relief; solder joint integrity critical for pulse energy dissipation |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4 kV, 2 Ω source) surge immunity on 24V/48V industrial buses |

| Lead-free, RoHS 3 & "Green" compliant | Meets automotive and industrial environmental mandates: Br+Cl <1500 ppm, Sb <1000 ppm |
| Fast response time | <1 ns turn-on enables suppression of ESD events (IEC 61000-4-2 ±8 kV contact) before downstream IC damage |
Applications
| Automotive Infotainment Power Input | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: 12V supply rail feeding head unit MCU and audio codec, exposed to load dump and jump-start transients. IC Role / Device Role: Primary clamping element placed upstream of LDO regulators and EMI filters. Use Value: Clamps 120V load dump spikes to ≤177V, preserving regulator input rating and preventing latch-up in downstream logic. |
Use Scenario: 4–20 mA current loop interface with ±15V auxiliary power, subject to field wiring induced surges. IC Role / Device Role: Bidirectional shunt protector across loop terminals and supply rails. Use Value: Symmetric clamping prevents reverse-polarity damage during hot-plug or miswiring, maintaining loop integrity. |
| Telecom Base Station DC Feeds | Medical Imaging Sensor Interface |
Use Scenario: –48V telecom power distribution board with multiple card slots and hot-swap capability. IC Role / Device Role: Point-of-load TVS on each slot's backplane connector. Use Value: Limits fault voltage to safe levels during insertion-induced arcing, protecting ASIC power pins. |
Use Scenario: Low-noise analog front-end for X-ray detector array, requiring sub-pF capacitance and low leakage. IC Role / Device Role: Secondary protection stage after ferrite bead, before precision op-amp inputs. Use Value: 177V clamping preserves ADC full-scale range during ESD events without adding signal-path capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110CA from Vishay (SMAJ110CA-E3/54) | Identical VRWM (110V), VBR (122–135V), VC (177V), and IPP (2.3A); same SMA package and RoHS compliance. | No functional difference; validated in identical automotive and industrial reference designs. | Select when dual-sourcing or second-source qualification is required for supply chain resilience. |
| P6SMB110CA from ON Semiconductor | Same electrical specs (VRWM=110V, VC=177V, IPP=2.3A), but P6SMB package has larger thermal mass (1.5W PM(AV)) and slightly longer lead time. | Better thermal handling for repetitive surges; requires PCB footprint redesign (DO-214AA vs. DO-214AC). | Choose only if system-level thermal testing shows SMAJ110CA-13-F exceeds junction temperature limits under burst-mode stress. |
Compared with SMAJ110CA-E3/54, this Diodes part offers identical protection performance with optimized logistics for tape-and-reel automated assembly; versus P6SMB110CA, it trades minor thermal margin for smaller footprint and faster availability - ideal for space-constrained, high-volume production.

FAQ
Is SMAJ110CA-13-F unidirectional or bidirectional?
SMAJ110CA-13-F is bidirectional, indicated by the "C" suffix in the part number per Diodes' datasheet DS19005. It has no polarity marking and provides symmetrical clamping for both positive and negative transients - confirmed by its identical VBR min/max values and absence of cathode band in mechanical drawings.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage is 177 V at 2.3 A peak pulse current (IPP), measured under standard 8.3 ms half-sine waveform conditions per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and represents the worst-case voltage imposed on protected circuitry during surge events.
Does this TVS diode meet automotive qualification standards?
The standard SMAJ110CA-13-F is not AEC-Q200 qualified; however, Diodes offers an automotive-compliant variant SMAJ110CAQ-13-F (documented separately) manufactured in IATF 16949-certified facilities and PPAP-capable. The "Q" suffix denotes automotive qualification - confirmed in DS19005 footnote referencing SMAJxxx(C)AQ series.
Can SMAJ110CA-13-F be used in place of SMAJ110A-13-F?
No - SMAJ110A-13-F is unidirectional (no "C"), with cathode band marking and asymmetric behavior: it conducts only during reverse overvoltage. Substituting it for SMAJ110CA-13-F in bidirectional applications (e.g., AC lines, differential pairs) will result in incomplete protection and potential failure during positive transients.
