Product details
Overview
SMBJ100CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 100 V standoff voltage (VWM), 111–123 V breakdown range (VBR), 162 V clamping voltage at 3.7 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines in industrial motor drives and telecom interface circuits.
For engineers reviewing the SMBJ100CAHE3_B/H datasheet, SMBJ100CAHE3_B/H pinout, SMBJ100CAHE3_B/H application, or SMBJ100CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient events exceeding VWM (100 V), it avalanches to limit voltage across protected circuitry to ≤162 V. Its bidirectional symmetry enables use without polarity consideration on AC-coupled or differential lines.
It delivers 600 W peak pulse power handling per 10/1000 µs waveform at TA = 25 °C, derating linearly above 25 °C with RθJA = 100 °C/W, and supports repetitive surge duty cycle ≤0.01 %. The junction temperature range spans –55 °C to +150 °C, and it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 111 V / 123 V at 1 mA test current - defines guaranteed avalanche onset window |
| VC @ IPPM | 162 V at 3.7 A - clamped voltage seen by protected circuit during full-rated transient |
| PPPM | 600 W - peak transient energy absorption capacity under standardized 10/1000 µs surge |
| RθJA | 100 °C/W - thermal resistance from junction to ambient, critical for PCB pad layout design |
| TJ max | +150 °C - maximum allowable junction temperature for reliable long-term operation |
| MSL Level | Level 1 (J-STD-020) - supports standard SMT reflow without dry-pack requirements |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking; matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Transient current return path | Bidirectional terminals - either end conducts during positive or negative transients; no cathode band marking |
| Anode (Cathode) | Transient current return path | Electrically symmetric - interchangeable in layout; no polarity-dependent routing required |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| 600 W peak pulse power | Withstands high-energy transients common in industrial motor drive switching and telecom line surges |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage stress on downstream ICs such as RS-485 transceivers or microcontroller I/O |
| MSL Level 1 | Enables direct placement into standard SMT reflow without baking or moisture-sensitive handling |
| Glass passivated junction | Ensures stable VBR and low leakage (<1 µA at VWM) across temperature and lifetime |
Applications
| Industrial Motor Drive Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: Protecting gate drivers and feedback sensors from inductive kickback during IGBT/MOSFET switching in variable-frequency drives. IC Role / Device Role / Timing Role: Shunt TVS diode placed across DC bus or signal inputs to clamp voltage spikes before they reach control ICs. Use Value: Limits transient voltage to ≤162 V, preventing latch-up or oxide damage in 100 V-rated gate drivers and isolated amplifiers. |
Use Scenario: Safeguarding RS-485 transceivers and PHY layer components on outdoor telecom node backhaul lines exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Bidirectional clamping element on differential pair (A/B) and common-mode lines to suppress ±1 kV EFT and induced surges. Use Value: Maintains signal integrity by clamping within 1.5 ns response time while surviving 600 W pulses per IEC 61000-4-5. |
| Automotive Body Control Module (BCM) | Consumer Power Adapter Input Stage |
Use Scenario: Suppressing load-dump and jump-start transients on 12 V supply rails feeding microcontrollers and CAN transceivers in BCMs. IC Role / Device Role / Timing Role: Primary front-end TVS on main power input, coordinated with upstream fuse and downstream LC filtering. Use Value: AEC-Q101 qualification ensures operation across –40 °C to +125 °C ambient, with clamping below 162 V even after 1000+ surge cycles. |
Use Scenario: Protecting AC-DC adapter primary-side rectifier and controller ICs from mains-borne surges and capacitor discharge transients. IC Role / Device Role / Timing Role: Secondary-side TVS on DC output rail (e.g., 12 V or 19 V) to prevent overvoltage damage to connected devices. Use Value: 100 V VWM matches typical adapter output tolerances; 162 V VC avoids triggering downstream OVP circuits unnecessarily. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA-M3/52 | Halogen-free, RoHS-compliant, commercial grade (no AEC-Q101 qualification) | Lacks automotive qualification; suitable for industrial/commercial designs without automotive compliance mandates | Select when AEC-Q101 is not required and halogen-free material compliance is prioritized |
| SAC100CA | Same VWM/VBR/VC specs but in smaller SOD-123FL package; lower PPPM (400 W), higher RθJA (150 °C/W) | Lower power handling and reduced thermal margin; limited to lower-energy transients or space-constrained layouts | Choose only for compact consumer designs where 400 W surge rating suffices and board area is critical |
Compared with SMBJ100CAHE3_B/H, SMBJ100CA-M3/52 offers identical electrical performance without automotive qualification, while SAC100CA trades power robustness and thermal performance for footprint reduction - making SMBJ100CAHE3_B/H the optimal choice for AEC-Q101-requiring, high-surge industrial and automotive systems.

FAQ
What is the clamping voltage of SMBJ100CAHE3_B/H at its rated peak pulse current?
The SMBJ100CAHE3_B/H has a maximum clamping voltage (VC) of 162 V at its rated peak pulse current (IPPM) of 3.7 A, measured using the standard 10/1000 µs waveform. This value ensures protected circuitry remains below critical overvoltage thresholds during surge events. The SMBJ100CAHE3_B/H maintains this clamping performance across its specified operating temperature range and after repeated surge exposure.
Is SMBJ100CAHE3_B/H suitable for automotive applications?
Yes, SMBJ100CAHE3_B/H is AEC-Q101 qualified, confirming its suitability for automotive applications including body control modules, infotainment power supplies, and sensor interface protection. Its construction includes glass-passivated junctions, MSL Level 1 moisture sensitivity rating, and validated performance across –55 °C to +150 °C junction temperature. The HE3 suffix explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature.
How does the bidirectional configuration of SMBJ100CAHE3_B/H affect PCB layout?
The SMBJ100CAHE3_B/H has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout for AC-coupled lines, differential pairs, or floating rails - no need for cathode band alignment or directional routing. Layout must still follow Vishay's recommended 5.0 mm × 5.0 mm copper pads per terminal to ensure rated thermal and surge performance.
What is the maximum steady-state power dissipation for SMBJ100CAHE3_B/H?
The SMBJ100CAHE3_B/H has a maximum steady-state power dissipation (PD) of 5.0 W at TA = 50 °C on an infinite heatsink. In real-world PCB conditions, its thermal resistance (RθJA = 100 °C/W) means power handling drops significantly with ambient temperature rise - e.g., ~2.5 W at TA = 75 °C. This rating applies only to continuous DC or low-frequency leakage, not transient suppression duty.
Does SMBJ100CAHE3_B/H meet UL recognition standards?
Yes, SMBJ100CAHE3_B/H carries Underwriters Laboratories (UL) recognition under file number E136766 for both unidirectional and bidirectional configurations, compliant with UL 497B for signal line protectors. This certification covers safety-related construction, flammability (UL 94 V-0 molding compound), and surge withstand capability - supporting use in UL-certified end equipment.
