Product details
Overview
SMBJ5.0CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 5.0 V stand-off voltage, 6.4–7.25 V breakdown voltage at 10 mA, and 600 W peak pulse power with 10/1000 µs waveform. It clamps transients to ≤9.2 V at 65.2 A, protecting sensitive ICs and MOSFETs in automotive and industrial power rails.
For engineers reviewing the SMBJ5.0CAHE3_A/H datasheet, SMBJ5.0CAHE3_A/H pinout, SMBJ5.0CAHE3_A/H application, or SMBJ5.0CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C junction temperature rating, low clamping voltage under surge, and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device across signal or power lines, responding in <1 ps to transient overvoltages. Its bidirectional symmetry enables protection of AC-coupled or differential interfaces without polarity constraints.
The device uses a glass-passivated silicon junction optimized for low incremental surge resistance (typical <0.1 Ω), fast response, and stable clamping under repetitive 0.01% duty-cycle surges. Thermal resistance is 100 °C/W junction-to-ambient (on recommended pad layout) and 20 °C/W junction-to-lead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 5.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| Breakdown Voltage (VBR) | 6.4–7.25 V at 10 mA - Confirmed minimum/maximum conduction onset; ensures reliable triggering above normal operating voltage. |
| Clamping Voltage (VC) | 9.2 V at 65.2 A (10/1000 µs) - Actual voltage seen by protected circuit during worst-case surge; critical for downstream component survivability. |
| Peak Pulse Power (PPPM) | 600 W - Sustained energy absorption capability under standardized lightning/surge waveform; validates robustness per IEC 61000-4-5. |
| Junction Temperature Range | -55 °C to +150 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JESD22 standards. |
| Package | SMB (DO-214AA) - Surface-mount footprint with 5.59 mm max length, 4.06 mm max width, and 2.20 mm max height; compatible with IPC-7351B standard land pattern. |
Pinout & Package
Package: SMB (DO-214AA), bidirectional configuration - no polarity marking; symmetrical anode/cathode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | Accepts surge current from either direction; connects to line being protected (e.g., CAN_H or DC rail). |
| Cathode | Transient current exit (bidirectional) | Completes surge path to ground or return rail; identical electrical role to Anode due to symmetric construction. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485, CAN), or ungrounded DC rails without polarity concerns. |
| 600 W peak pulse power (10/1000 µs) | Meets Level 4 IEC 61000-4-5 surge immunity requirements for industrial and automotive applications. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body electronics, and ADAS modules requiring long-term field reliability. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage stress on protected ICs-critical for 5 V logic, microcontrollers, and gate drivers with tight absolute maximum ratings. |
| MSL Level 1 (260 °C peak reflow) | Supports lead-free soldering without pre-baking; eliminates moisture-related popcorning risk during SMT assembly. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12 V battery-supplied ECUs exposed to load dump (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS placed between VBAT and GND to clamp transients up to ±100 V. Use Value: Limits voltage seen by MCU and CAN transceivers to ≤9.2 V, preventing latch-up or oxide breakdown during 65.2 A surges. |
Use Scenario: Analog sensor outputs (e.g., pressure, temperature) routed through noisy factory environments. IC Role / Device Role / Timing Role: TVS mounted across differential pair (e.g., RS-485 A/B) or single-ended signal and ground. Use Value: Suppresses ESD (IEC 61000-4-2) and EFT (IEC 61000-4-4) events without distorting low-bandwidth sensor signals. |
| Telecom Line Card Surge Protection | Consumer USB Port ESD Clamping |
|
Use Scenario: DSL or PoE-powered line cards subjected to lightning-induced surges on twisted-pair inputs. IC Role / Device Role / Timing Role: Primary protection stage before secondary polymer PTC and filtering network. Use Value: Absorbs 600 W surge energy while maintaining <1 µA leakage at 5.0 V, preserving signal integrity and low-power standby operation. |
Use Scenario: USB 2.0 data lines (D+/D−) in portable devices vulnerable to human-body-model ESD. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector, shunting ESD current to chassis ground. Use Value: Clamps ±15 kV contact discharge to <12 V within <1 ns, protecting USB PHY transceivers without adding capacitance >100 pF. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA-E3/52 | Same electrical specs, RoHS-compliant commercial grade (non-AEC-Q101); MSL Level 1, same SMB package. | Lacks automotive qualification; suitable for consumer/industrial designs not requiring AEC-Q101 traceability. | Select when cost sensitivity outweighs automotive reliability requirements and full lifecycle support is not mandated. |
| SMCJ5.0CAHE3_A/H | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; 1500 W PPPM rating; RθJA = 35 °C/W. | Higher power handling supports longer surge durations or higher repetition rates; requires larger PCB area. | Choose when system-level surge testing exceeds 600 W or thermal management demands lower junction rise per watt. |
Compared with SMBJ5.0CAHE3_A/H, the E3/52 variant trades automotive qualification for lower unit cost in non-automotive systems, while the SMCJ5.0CAHE3_A/H offers 2.5× higher surge power in a physically larger footprint-enabling design margin scaling without changing circuit topology.
