Product details
Overview
SMAJ60CA-13-F from Diodes Incorporated is a bidirectional 400W surface-mount transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 60V reverse standoff voltage (VRWM), 66.7–73.7V breakdown voltage (VBR), 96.8V max clamping voltage (VC) at 4.1A peak pulse current (IPP), and operates across –55°C to +150°C. It is used in automotive infotainment power rails to suppress ESD and load-dump transients.
For engineers reviewing the SMAJ60CA-13-F datasheet, SMAJ60CA-13-F pinout, SMAJ60CA-13-F application, or SMAJ60CA-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, and IATF 16949-manufactured alternatives for automotive qualification.
Technical Context
This TVS diode uses glass-passivated junction construction for stable breakdown behavior and fast response (<1 ns) to transients such as ISO 7637-2 pulse 1/2a/5a and IEC 61000-4-2 ESD events. Its bidirectional configuration enables symmetric clamping on AC-coupled or floating signal lines without polarity concerns.
It is rated for 400W non-repetitive peak pulse power (8.3 ms half-sine), with steady-state power dissipation of 1.0 W at TL = +75°C and thermal resistance θJA ≈ 125°C/W (typical for SMA package). Clamping performance is validated at IT = 1.0 mA and IPP = 4.1 A under standardized test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W - Withstands single 8.3 ms transient surges up to this energy level without failure. |
| Reverse Standoff Voltage (VRWM) | 60 V - Maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected circuit operating voltage. |
| Breakdown Voltage (VBR) | 66.7–73.7 V @ IT = 1.0 mA - Confirmed avalanche initiation range; ensures reliable turn-on before downstream component damage. |
| Max Clamping Voltage (VC) | 96.8 V @ IPP = 4.1 A - Upper voltage seen by protected circuit during worst-case surge; defines safe margin for 75 V-rated components. |
| Peak Pulse Current (IPP) | 4.1 A - Peak current capability at rated clamping voltage; determines survivability against defined transient waveforms. |
| Operating Temperature | –55°C to +150°C - Validated junction temperature range for under-hood automotive and industrial environments. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with 2.29–2.92 mm body width; compatible with automated reflow assembly. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with UL 94V-0 flammability rating, cathode band omitted (bidirectional device).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Identical terminals; bidirectional operation allows connection across any two points without polarity orientation. |
| Case / Body | Thermal and mechanical interface | No electrical connection; serves as primary heat path to PCB copper; requires adequate thermal pad area per Diodes' layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse power | Enables robust protection against ISO 7637-2 load dump and jump-start surges in 12 V automotive systems. |
| Glass-passivated die | Ensures stable VBR over lifetime and temperature; eliminates parameter drift due to moisture or contamination ingress. |
| Bidirectional configuration | Supports AC signal line protection (e.g., CAN bus, audio inputs) without requiring external polarity management. |
| RoHS-compliant & halogen-free | Meets automotive ELV directive and IPC-1752A reporting requirements; no bromine <900 ppm, antimony <1000 ppm. |
| Moisture Sensitivity Level 1 | Eliminates bake preconditioning prior to reflow; supports standard SMT manufacturing flow without handling restrictions. |
Applications
| Automotive Infotainment Power Rail | CAN Bus Physical Layer |
|---|---|
Use Scenario: Protects 5 V/12 V power inputs to head unit MCUs and display drivers from battery transients and ESD. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of LDOs and PMICs; responds within <1 ns to divert surge current. Use Value: Limits voltage excursion to ≤96.8 V during 4.1 A load dump event, preserving 100 V-rated input capacitors and gate oxides. |
Use Scenario: Installed on CAN_H/CAN_L lines between transceiver and connector to suppress ESD and coupled noise. IC Role / Device Role / Timing Role: Bidirectional shunt element that clamps both positive and negative transients symmetrically. Use Value: Maintains signal integrity by limiting differential voltage swing to <2×96.8 V while adding <1.5 pF typical capacitance at 1 MHz. |
| Industrial PLC Digital I/O Module | Smart Meter Communication Interface |
Use Scenario: Shields 24 V DC input/output channels from induced surges in factory floor wiring. IC Role / Device Role / Timing Role: First-line transient suppression before optocoupler or digital isolator inputs. Use Value: Survives repeated 1 kV/500 A ring wave tests per IEC 61000-4-5 Level 3 when mounted with 200 mm² copper pour. |
Use Scenario: Protects RS-485 and HPLC PHY lines in electricity meters exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp minimizing signal distortion on multi-drop bus. Use Value: Adds only 1.5 pF capacitance at 1 MHz, preserving >500 kbps data rate integrity on 120 Ω terminated lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-13-F | Unidirectional version; same VRWM, VBR, VC, and IPP but conducts only in reverse direction. | Required where polarity is fixed (e.g., DC power rail with known ground reference); not suitable for AC or floating signals. | Select only if system topology guarantees consistent voltage polarity and no negative transients occur. |
| SMAJ60CAQ-13-F | Automotive-qualified variant per AEC-Q101; identical electrical specs but manufactured in IATF 16949 facility with PPAP support. | Mandatory for production automotive ECUs; includes extended reliability testing (HTOL, TCT, ESD HBM/MM) and change control. | Choose for Tier 1 OEM programs requiring full automotive traceability and qualification documentation. |
Compared with SMAJ60CA-13-F, the unidirectional SMAJ60A-13-F reduces design flexibility on bidirectional lines, while the AEC-Q101 SMAJ60CAQ-13-F adds qualification overhead but enables direct use in safety-critical vehicle subsystems without requalification.

FAQ
What is the maximum clamping voltage of SMAJ60CA-13-F at its rated peak pulse current?
The maximum clamping voltage (VC) is 96.8 V at a peak pulse current (IPP) of 4.1 A, measured using a 10/1000 µs waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and represents the highest voltage imposed on the protected circuit during surge conduction.
Is SMAJ60CA-13-F suitable for protecting CAN FD interfaces?
Yes - its 1.5 pF typical capacitance at 1 MHz and bidirectional symmetry make it compatible with CAN FD data rates up to 5 Mbps. However, layout must minimize trace inductance and maintain differential impedance; placement directly at the connector is recommended to avoid stub effects.
Does SMAJ60CA-13-F require derating at elevated ambient temperatures?
Yes - its peak pulse power must be linearly derated above +25°C per Figure 1 in DS19005. At +85°C ambient, usable peak power drops to ~70% of 400 W (≈280 W), and clamping voltage may increase slightly due to junction heating during sustained surge events.
How does the SMA package of SMAJ60CA-13-F impact thermal performance in high-reliability applications?
The SMA (DO-214AC) package has a typical θJA of 125°C/W on standard FR-4 with minimal copper. For high-reliability use, Diodes recommends a 200 mm² thermal pad connected to internal ground planes via ≥4 thermal vias to reduce θJA to ~45°C/W, enabling sustained operation near TJ = +150°C.
