Product details
Overview
TPSMB16AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage at 26.7 A peak pulse current, 600 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - used in automotive sensor protection and industrial power rail surge suppression.
For engineers reviewing the TPSMB16AHE3_A/I datasheet, TPSMB16AHE3_A/I pinout, TPSMB16AHE3_A/I application, or TPSMB16AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 10 µA max reverse leakage at VWM, and compatibility with high-reliability PCB assembly processes including 260 °C lead-free reflow.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge conditions. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments and industrial control systems where thermal derating and long-term reliability are critical.
The device responds within picoseconds to transient overvoltages and maintains low incremental surge resistance during 10/1000 µs waveform events. Its cathode-band polarity marking and matte tin-plated terminals comply with J-STD-002 solderability and JESD 22-B102 whisker resistance Class 2 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - ensures reliable turn-on before downstream IC damage threshold |
| VWM | 13.6 V - blocks normal operating voltage while allowing margin for ripple and tolerance |
| VC @ IPPM | 22.5 V - clamps transient energy to safe level for 15 V-rated circuits |
| PPPM | 600 W - handles standard 10/1000 µs surge pulses without degradation |
| IFSM | 75 A - withstands 8.3 ms half-sine surge events common in motor drive switching |
| TJ max. | +185 °C - supports operation in engine control units and power converters with high ambient heat |
| Leakage @ VWM | 1 µA - negligible standby current draw in battery-powered sensor nodes |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode indicated by color band. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H). RoHS-compliant, halogen-free option available (HM3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference plane to complete clamping loop |
| Cathode | Transient voltage sensing node | Connected to protected line (e.g., 12 V rail or CAN_H); color band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|

| Low clamping ratio (VC/VBR) | 1.41 - delivers tight voltage limiting relative to breakdown, minimizing overvoltage exposure |
| Fast response time | < 1 ns - activates before most microcontrollers or MOSFETs can be damaged by ESD or inductive kick |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protecting 12 V supply rails and LIN bus lines from load dump and alternator ripple in BCM modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Same SMB package, 16 V VBR, but rated for 600 W with 10/1000 µs waveform and not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 compliance is not required and cost sensitivity outweighs qualification needs |
| SMCJ16A | Higher 1500 W PPPM, same VBR, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm) | Requires PCB layout change due to footprint mismatch; better for higher-energy threats | Choose only if system-level surge testing exceeds 600 W and board space permits larger footprint |
Compared with SMBJ16A and SMCJ16A, the TPSMB16AHE3_A/I uniquely combines AEC-Q101 qualification, SMB footprint, and 185 °C operation - making it the only drop-in solution for thermally constrained automotive modules requiring zero-layout-change upgrades from legacy TVS devices.

FAQ
What is the maximum clamping voltage of the TPSMB16AHE3_A/I under specified test conditions?
The TPSMB16AHE3_A/I has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 26.7 A using the standard 10/1000 µs waveform. This value is measured per JEDEC standards and confirmed in Vishay's official datasheet revision 23-Jan-2024 (Document Number: 88406). The clamping performance ensures protected circuits remain within safe operating limits during transient events.
Is the TPSMB16AHE3_A/I qualified for automotive applications?
Yes, the TPSMB16AHE3_A/I is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet under "FEATURES" and "ORDERING INFORMATION". The HE3 suffix denotes RoHS-compliance and AEC-Q101 qualification. This makes the TPSMB16AHE3_A/I suitable for use in automotive subsystems such as body control modules, sensor interfaces, and infotainment power supplies where qualification is mandatory.
What does the "HE3_A/I" suffix mean in TPSMB16AHE3_A/I?
The "HE3" suffix indicates RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 Class 2 whisker resistance. "A" is the revision code; "I" denotes packaging in 13-inch plastic tape and reel with 3200 units per reel. This full ordering code distinguishes the TPSMB16AHE3_A/I from non-automotive or differently packaged variants like TPSMB16AHM3_A/H.
Can the TPSMB16AHE3_A/I replace older SMB-format TVS diodes without layout changes?
Yes - the TPSMB16AHE3_A/I uses the standard SMB (DO-214AA) package with identical mechanical dimensions and terminal layout as legacy SMB TVS devices. Its 4.57 mm × 3.94 mm outline and cathode-band polarity marking ensure direct PCB footprint compatibility. No layout or stencil changes are needed when upgrading from non-qualified or lower-temperature-rated SMB TVS parts.
What is the reverse leakage current specification for TPSMB16AHE3_A/I at its stand-off voltage?
At 25 °C and its rated stand-off voltage (VWM) of 13.6 V, the TPSMB16AHE3_A/I exhibits a maximum reverse leakage current (IR) of 1 µA. At elevated temperature (TJ = 150 °C), leakage rises to ≤ 5 µA - a value verified in the Electrical Characteristics table of the Vishay datasheet and critical for low-power sensor and battery-backed applications.
