Product details
Overview
TPSMB16A-1BHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive switching transients and lightning-induced surges on power rails and signal lines. It features 16.0 V nominal breakdown voltage (VBR), 13.6 V maximum stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 26.7 A peak pulse current (IPPM), and 22.5 V maximum clamping voltage (VC) - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the TPSMB16A-1BHE3_A/I datasheet, TPSMB16A-1BHE3_A/I pinout, TPSMB16A-1BHE3_A/I application, or TPSMB16A-1BHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 185 °C junction temperature rating, low incremental surge resistance, and compatibility with high-reliability PCB assembly processes including MSL Level 1 and JESD 201 Class 2 whisker testing.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR = 15.2–16.8 V (at IT = 1 mA), it avalanches to limit transient energy by diverting surge current to ground. Its anisotropic rectifier structure enables fast response (<1 ns) and stable clamping under repetitive 0.01% duty cycle pulses.
Thermal design is enabled by TJmax = 185 °C capability and derating curves per Figure 2; mechanical robustness is assured via matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and UL 94 V-0 molding compound - all validated for automotive-grade reliability per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V at 1 mA - defines precise avalanche initiation threshold for predictable clamping onset |
| VWM | 13.6 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 22.5 V - clamped voltage during 26.7 A 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 600 W - peak transient power handling capacity under standardized waveform, enabling robust ESD/Lightning immunity |
| IFSM | 75 A - 8.3 ms half-sine surge current rating, supporting motor drive and relay coil suppression |
| TJ range | −65 °C to +185 °C - extended thermal envelope for under-hood automotive and industrial environments |
| Polarity | Unidirectional - protects against negative transients only; cathode marked by band |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, single-diode configuration with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); 0.220" × 0.155" mounting pad layout recommended.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or clamping | Connected to protected line (e.g., 12 V rail); must be routed with low-inductance path to ground |
| Cathode | Current exit point during reverse avalanche clamping | Connected to system ground; color band identifies this terminal; critical for correct polarity installation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - supports PPAP and long-term field reliability |
| Junction passivated anisotropic rectifier | Enables stable VBR over temperature and lifetime, with <0.1% drift per 1000 hrs at 150 °C |
| MSL Level 1, 260 °C reflow compatible | Zero moisture sensitivity risk - no bake required prior to SMT assembly |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a), improving protection margin |
| Halogen-free & RoHS-compliant (HE3 suffix) | Meets global environmental compliance mandates without compromising electrical performance or thermal robustness |
Applications
| Automotive Sensor Protection | Industrial Power Input Stage |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and inductive kickback in engine control units. IC Role / Device Role / Timing Role: Shunt clamping device placed between signal line and chassis ground, activated within nanoseconds of overvoltage event. Use Value: Limits transient voltage to ≤22.5 V, preventing damage to 3.3 V/5 V interface ICs rated for ≤30 V absolute maximum. |
Use Scenario: Safeguarding AC-DC and DC-DC converter inputs against 1 kV/µs surges from relay switching or grid disturbances in PLCs and motor drives. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V or 48 V DC input rail, coordinated with upstream fuse and downstream filtering. Use Value: Absorbs 600 W peak pulse energy without degradation, maintaining system uptime under repeated surge stress. |
| Consumer Device USB Port Protection | Telecom Line Interface |
Use Scenario: Guarding USB 2.0 data lines and VBUS against ESD (±15 kV contact) and cable discharge events in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Low-capacitance (CJ ≈ 100 pF at 0 V) unidirectional TVS placed inline with D+/D− and VBUS traces. Use Value: Clamps ESD pulses to <25 V within <1 ns, preserving signal integrity while meeting IEC 61000-4-2 Level 4. |
Use Scenario: Shielding Ethernet PHY interfaces and POTS line drivers from lightning-induced surges in base station backhaul and DSLAM equipment. IC Role / Device Role / Timing Role: Secondary-level protector mounted adjacent to RJ-45 connector, downstream of gas discharge tube (GDT). Use Value: Provides precise 22.5 V clamping after GDT crowbar action, preventing latch-up in 3.3 V PHY ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VBR (16.0 V), but lower PPPM = 400 W; SMA package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select when cost or board space is prioritized over automotive qualification and 600 W surge margin |
| TPSMB16CA | Bi-directional variant (±16 V symmetric clamping); identical package, power rating, and AEC-Q101 status | Required for AC-coupled or bidirectional signal lines (e.g., RS-485, audio), where negative transients also occur | Choose only if protection against both polarities is mandated - otherwise TPSMB16A-1BHE3_A/I offers superior VWM margin for DC rails |
Compared with SMAJ16A and TPSMB16CA, the TPSMB16A-1BHE3_A/I delivers optimal balance of automotive qualification, 600 W surge capacity, and 13.6 V stand-off margin for unidirectional DC power/signal protection - making it the preferred choice for AEC-Q101-compliant designs where polarity is known and fixed.

FAQ
What is the exact breakdown voltage tolerance for TPSMB16A-1BHE3_A/I?
The TPSMB16A-1BHE3_A/I has a guaranteed breakdown voltage range of 15.2 V to 16.8 V at 1 mA test current, with 16.0 V as the nominal value. This ±5% tolerance ensures consistent clamping behavior across production lots and temperature extremes up to 150 °C, as confirmed in the Electrical Characteristics table on page 2 of Vishay document 88406.
Is TPSMB16A-1BHE3_A/I AEC-Q101 qualified?
Yes, TPSMB16A-1BHE3_A/I is AEC-Q101 qualified. The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified construction, verified per the ordering information section and Mechanical Data notes in Vishay document 88406. This qualification covers temperature cycling, humidity bias, and mechanical shock tests required for automotive electronics.
What does the "-1B" in TPSMB16A-1BHE3_A/I signify?
The "-1B" suffix in TPSMB16A-1BHE3_A/I indicates the revision code per Vishay's naming convention: "1B" denotes a specific manufacturing revision level tied to process and material updates. It appears in the base part number field in the Ordering Information table (page 2) and correlates with the "_X" placeholder described as denoting revision codes like A, B, etc.
Can TPSMB16A-1BHE3_A/I replace SMAJ16A in existing designs?
TPSMB16A-1BHE3_A/I is not a direct drop-in replacement for SMAJ16A due to different package outlines (SMB vs. SMA) and higher power rating (600 W vs. 400 W). While both share 16 V VBR, the TPSMB16A-1BHE3_A/I requires updated PCB land pattern and offers enhanced surge capability - redesign is needed to leverage its full automotive-grade performance.
What is the maximum clamping voltage of TPSMB16A-1BHE3_A/I under surge conditions?
The TPSMB16A-1BHE3_A/I has a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current of 26.7 A (10/1000 µs waveform), as specified in the Electrical Characteristics table. This value represents the worst-case voltage seen by downstream circuitry during a full-rated transient event.
