Product details
Overview
SMBJ130CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR), 600 W peak pulse power (10/1000 µs), and clamps to ≤209 V at 2.9 A peak surge current - deployed in industrial sensor interfaces and telecom line protection.
For engineers reviewing the SMBJ130CAHE3/52 datasheet, SMBJ130CAHE3/52 pinout, SMBJ130CAHE3/52 application, or SMBJ130CAHE3/52 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with UL 497B for surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 130 V), then rapidly switches to low-impedance conduction when transient voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
The SMBJ130CAHE3/52 is rated for repetitive 10/1000 µs surges at 0.01% duty cycle, derates linearly above 25 °C per Fig. 2, and maintains clamping performance across -55 °C to +150 °C junction temperature range. Its bidirectional symmetry enables use without polarity consideration on AC-coupled or differential lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 144 V / 159 V at 1 mA - guaranteed breakdown threshold window defining turn-on consistency |
| VC @ IPPM | 209 V at 2.9 A - clamped voltage during full-rated 600 W transient, limiting downstream stress |
| PPPM | 600 W (10/1000 µs) - peak surge energy handling capacity for lightning or inductive switch-off events |
| ID @ VWM | 1.0 µA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| TJ max | +150 °C - extended thermal rating supports operation in enclosed industrial enclosures |
| RθJA | 100 °C/W - thermal resistance defines required PCB copper area (0.2" × 0.2") for safe 5 W steady-state dissipation |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, MSL Level 1 (260 °C reflow peak), UL 94 V-0 molding compound. Bidirectional construction means no polarity marking; both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Connects to protected line; conducts surge current toward ground or rail during either polarity excursion |
| Cathode | Transient return path (bidirectional) | Electrically identical to Anode; no functional distinction in CA-suffix devices - symmetrical clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness - suitable for under-hood ECUs |
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 (4 kV) surges on 2 Ω source impedance without failure |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh environments |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage exposure to downstream ICs - critical for 3.3 V or 5 V logic interface protection |
| MSL Level 1 | Enables standard SMT reflow without baking or special handling - reduces manufacturing overhead |
Applications
| Industrial Sensor Interface | Telecom Line Protection |
|---|---|
|
Use Scenario: Protecting RS-485 transceivers and analog sensor outputs (e.g., 4–20 mA loops) from ESD and inductive switching transients in factory automation cabinets. IC Role / Device Role / Timing Role: Shunt TVS clamp placed between signal line and ground, absorbing >95% of transient energy before it reaches the transceiver input stage. Use Value: Prevents latch-up or permanent damage to MAX1487 or ADuM1201-level isolators during 4 kV contact ESD events per IEC 61000-4-2. |
Use Scenario: Safeguarding Ethernet PHY front-end circuits (e.g., RJ45 magnetics secondary side) against lightning-induced surges in outdoor access points. IC Role / Device Role / Timing Role: Bidirectional voltage clamp across differential pairs (e.g., TX+/TX−), activated within <1 ns to limit common-mode overvoltage. Use Value: Maintains signal integrity up to 100 Mbps while surviving 10/700 µs telecom surges per ITU-T K.21 Basic Level. |
| Automotive Body Control Module | Power Supply Input Stage |
|
Use Scenario: Suppressing load-dump transients (ISO 7637-2 Pulse 5a) on 12 V supply rails feeding LIN bus gateways and door module MCUs. IC Role / Device Role / Timing Role: Primary clamping device parallel to bulk input capacitor, triggered before upstream fuse opens. Use Value: Limits rail voltage to ≤209 V during 35 V/100 ms load dump, preventing overvoltage shutdown of TLE9879-based controllers. |
Use Scenario: Guarding DC-DC converter inputs (e.g., LM5017) against back-EMF from relay coils and motor drivers in embedded power systems. IC Role / Device Role / Timing Role: Fast-response shunt element across input filter capacitor, diverting surge current away from regulator pass transistor. Use Value: Enables reliable operation with 600 W transient margin - sufficient for 100 V/10 A inductive kick suppression per MIL-STD-1275E. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-M3/52 | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification | No difference in circuit function or layout; differs only in material composition for environmental compliance | Select when halogen-free BOM requirements apply (e.g., EU public infrastructure tenders) |
| SMCJ130CAHE3/52 | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package - higher RθJA (50 °C/W) and 1500 W PPPM | Requires larger PCB footprint; suited for higher-energy surges where 600 W is insufficient | Choose only if system-level testing confirms need for >600 W surge margin - otherwise SMBJ130CAHE3/52 saves board space |
Compared with SMBJ130CA-M3/52, the SMBJ130CAHE3/52 offers identical protection performance with standard RoHS compliance; versus SMCJ130CAHE3/52, it trades 2.5× lower thermal resistance and 2.5× higher surge rating for 30% smaller PCB area - optimal for space-constrained industrial modules.

FAQ
What does the "CA" suffix indicate in SMBJ130CAHE3/52?
The "CA" suffix denotes a bidirectional configuration: SMBJ130CAHE3/52 provides symmetrical clamping for both positive and negative transients, unlike unidirectional "A" variants that require correct polarity orientation. This eliminates orientation errors during placement and simplifies design for AC-coupled or differential signal paths - a key feature confirmed in Vishay's datasheet section "DEVICES FOR BIDIRECTION APPLICATIONS".
Is SMBJ130CAHE3/52 qualified for automotive use?
Yes, SMBJ130CAHE3/52 is AEC-Q101 qualified, as explicitly stated in the "MECHANICAL DATA" section of the Vishay datasheet (Document Number: 88392). The "HE3" suffix indicates RoHS-compliant and AEC-Q101 qualified construction, validated for temperature cycling, highly accelerated life testing, and ESD robustness - making SMBJ130CAHE3/52 suitable for under-hood and chassis-mounted automotive modules.
What is the clamping voltage of SMBJ130CAHE3/52 at its rated surge current?
The clamping voltage (VC) of SMBJ130CAHE3/52 is 209 V at 2.9 A peak pulse current (IPPM), measured using the standard 10/1000 µs waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table for SMBJ130A/SMBJ130CA entries and defines the maximum voltage imposed on protected circuitry during full-rated transient events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings.
How does SMBJ130CAHE3/52 differ from SMBJ130AHE3/52?
SMBJ130CAHE3/52 is bidirectional with symmetrical clamping, while SMBJ130AHE3/52 is unidirectional and features a cathode band for polarity identification. Electrically, SMBJ130AHE3/52 has forward voltage drop (VF ≤ 3.5 V at 50 A) and IFSM = 100 A, whereas SMBJ130CAHE3/52 has no VF specification and omits IFSM due to bidirectional structure - confirming distinct internal architecture and application scope per Vishay's "PRIMARY CHARACTERISTICS" table.
What PCB pad layout is recommended for SMBJ130CAHE3/52?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area per terminal for SMBJ130CAHE3/52 to achieve rated 600 W pulse power and thermal performance. This layout is documented in the "MAXIMUM RATINGS" footnote (2) and Fig. 1 - undersized pads reduce surge capability and increase junction temperature, risking premature failure during repetitive transients.
