Product details
Overview
TPSMA16AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in SMA (DO-214AC) package, rated for 16 V breakdown voltage (VBR = 15.2–16.8 V at 1.0 mA), 400 W peak pulse power (10/1000 µs), 22.0 V maximum clamping voltage at 17.8 A, and 185 °C junction temperature capability - deployed for ESD and surge protection on automotive sensor signal lines and MOSFET gate drivers.
For engineers reviewing the TPSMA16AHE3_B/H datasheet, TPSMA16AHE3_B/H pinout, TPSMA16AHE3_B/H application, or TPSMA16AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, TJ = 185 °C thermal rating, 22.0 V clamping performance at rated IPPM, and SMA package compatibility with high-reliability automotive PCB layouts.
Technical Context
This device operates as a silicon avalanche diode optimized for fast transient suppression, using passivated anisotropic rectifier technology to deliver sub-nanosecond response time and low incremental surge resistance. Its unidirectional configuration enables robust protection of DC-biased signal paths without forward conduction during normal operation.
Designed for automotive-grade reliability, TPSMA16AHE3_B/H meets AEC-Q101 qualification, supports MSL Level 1 reflow (260 °C peak), and maintains stable VBR across -65 °C to +185 °C operating range with αT = 0.078 %/°C temperature coefficient - enabling use in under-hood and powertrain control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V at 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping behavior |
| VWM | 13.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 22.0 V at 17.8 A - clamping voltage under 400 W 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 400 W - peak pulse power handling per JEDEC standard waveform, supporting IEC 61000-4-5 Level 4 immunity |
| TJ max. | +185 °C - enables placement near heat sources (e.g., power converters) without derating |
| Polarity | Unidirectional - protects only reverse-polarity transients; requires correct cathode orientation on PCB |
| Package | SMA (DO-214AC) - industry-standard SMD outline with 0.208" x 0.157" footprint and matte tin-plated leads |
Pinout & Package
SMA (DO-214AC) package with axial lead configuration: molded plastic body, cathode band marking, and two terminals - anode and cathode - mounted on PCB via 5.0 mm × 5.0 mm copper pads per terminal per JEDEC specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VREV > VBR |
| Anode | Reference node | Typically tied to system ground or low-impedance return path for clamping loop integrity |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR and low leakage over lifetime and temperature |
| AEC-Q101 qualification | Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
| MSL Level 1 | Compatible with standard SMT reflow profiles up to 260 °C peak, eliminating moisture sensitivity concerns |
| Low clamping ratio (VC/VBR) | 1.375 - tight ratio minimizes overvoltage exposure to protected ICs during surge events |
| High IFSM | 40 A - withstands repetitive 8.3 ms half-sine surges common in motor drive and relay switching |
Applications

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 range (15.2–16.8 V), identical SMA package, but not AEC-Q101 qualified and rated for 400 W at 25 °C only (no 185 °C TJ rating) | Limited to commercial/industrial environments; unsuitable for under-hood automotive deployment | Select SMAJ16A only if AEC-Q101 compliance and extended temperature operation are not required |
| TPSMA16AHM3_B/H | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound and JESD201 Class 2 whisker resistance | No functional difference; used where RoHS + halogen-free compliance is mandated (e.g., EU automotive Tier 1) | Choose TPSMA16AHM3_B/H when halogen-free material compliance is contractually required |
Compared with SMAJ16A and TPSMA16AHM3_B/H, TPSMA16AHE3_B/H provides AEC-Q101 qualification and 185 °C junction rating in a RoHS-compliant package - making it the preferred choice for automotive signal-line protection where thermal robustness and automotive qualification are mandatory, while TPSMA16AHM3_B/H adds halogen-free assurance without sacrificing performance.

FAQ
What is the clamping voltage of TPSMA16AHE3_B/H at its rated peak pulse current?
The TPSMA16AHE3_B/H has a maximum clamping voltage (VC) of 22.0 V at its rated peak pulse current (IPPM) of 17.8 A, measured under the standard 10/1000 µs waveform. This value ensures that protected downstream circuitry, such as microcontrollers or gate drivers, remains within safe voltage limits during surge events. The clamping performance is guaranteed across the full operating temperature range and is integral to the device's role in IEC 61000-4-5 compliant designs.
Is TPSMA16AHE3_B/H qualified for automotive applications?
Yes, TPSMA16AHE3_B/H is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101-qualified variants. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), validating its suitability for under-hood and powertrain control module applications where reliability is critical.
What does the "HE3" suffix mean in TPSMA16AHE3_B/H?
The "HE3" suffix in TPSMA16AHE3_B/H indicates a RoHS-compliant, AEC-Q101-qualified version with matte tin-plated leads and JESD201 Class 2 whisker resistance. The "B/H" denotes packaging in 7-inch plastic tape-and-reel format with 1800 units per reel. This suffix distinguishes it from non-automotive variants (e.g., base TPSMA16A) and halogen-free alternatives (e.g., HM3), ensuring traceability to automotive-grade manufacturing and testing standards.
How does TPSMA16AHE3_B/H differ from TPSMA16AHM3_B/H?
TPSMA16AHE3_B/H and TPSMA16AHM3_B/H share identical electrical specifications, AEC-Q101 qualification, and SMA package dimensions. The sole difference is material composition: TPSMA16AHM3_B/H uses halogen-free molding compound and meets additional JESD201 Class 2 whisker resistance requirements, whereas TPSMA16AHE3_B/H is RoHS-compliant but not halogen-free. Both are fully interchangeable electrically and mechanically in most designs.
What is the maximum operating junction temperature for TPSMA16AHE3_B/H?
The maximum operating junction temperature (TJmax) for TPSMA16AHE3_B/H is +185 °C, verified per Vishay's datasheet revision 23-Jan-2024. This rating enables reliable operation in high-temperature environments such as engine compartments or near power converters, and supports full-rated power dissipation without thermal derating up to this limit - a key differentiator versus commercial-grade TVS diodes limited to 150 °C.
