Product details
Overview
TPSMA16A61HE3J_B/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SMA (DO-214AC) 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), 22.0 V maximum clamping voltage (VC) at 17.8 A peak pulse current, 400 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the TPSMA16A61HE3J_B/H datasheet, TPSMA16A61HE3J_B/H pinout, TPSMA16A61HE3J_B/H application, or TPSMA16A61HE3J_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 13.6 V working voltage compatibility with 12 V rail systems, and thermal derating behavior above 25 °C ambient.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its junction design enables reliable operation at TJ = 185 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
The device delivers fast response time and excellent clamping performance under 10/1000 µs surge waveforms. It is rated for 40 A non-repetitive forward surge current (IFSM) and exhibits 0.078 %/°C temperature coefficient of VBR, enabling predictable voltage threshold shift across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 V / 16.0 V / 16.8 V - defines precise voltage threshold at which avalanche conduction begins under 1.0 mA test current |
| VWM | 13.6 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA, compatible with 12 V nominal systems |
| VC @ IPPM | 22.0 V at 17.8 A - clamped voltage during 400 W transient, limiting downstream IC stress to safe levels |
| PPPM | 400 W (10/1000 µs) - peak surge power handling capacity for lightning and inductive switching events |
| TJ max. | +185 °C - enables use in under-hood automotive and high-ambient industrial environments without thermal derating failure |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation toward protected line |
| Package | SMA (DO-214AC) - industry-standard surface-mount outline with 0.208" x 0.157" footprint and matte tin-plated leads |
Pinout & Package
TPSMA16A61HE3J_B/H uses the SMA (DO-214AC) package: molded plastic case with cathode band marking, 0.208" × 0.157" body, 0.078" lead spacing, and matte tin-plated terminals compliant with J-STD-002 solderability and JESD 22-B102 whisker testing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; completes clamping loop during transient |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V supply or CAN_H); color band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard |
| Junction passivation | Reduces surface leakage and improves long-term stability under humid, high-bias conditions |
| MSL Level 1 | Zero floor life limitation; supports standard SMT reflow up to 260 °C peak without baking |
| Low VC/VBR ratio | 22.0 V / 16.0 V = 1.375 - tight clamping margin ensures minimal overvoltage exposure to downstream ICs |
| 0.078 %/°C αT | Predictable VBR drift allows accurate system-level transient margining across -65 °C to +185 °C range |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Same VBR (16.0 V), but SMB package (DO-214AA); 600 W PPPM; higher VC = 26.0 V | Larger footprint (0.236" × 0.157"); better suited for higher-energy surges where board space permits | Select when 600 W rating is required and PCB layout accommodates larger SMB outline |
| 1.5SMC16A | Same VBR, but SMC package (DO-214AB); 1500 W PPPM; VC = 26.0 V; higher IFSM = 200 A | Substantially larger (0.295" × 0.236"); intended for primary-level surge protection rather than board-level clamping | Choose for front-end AC/DC input protection where higher surge robustness outweighs size constraints |
Compared with SMBJ16A and 1.5SMC16A, TPSMA16A61HE3J_B/H offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and precise 22.0 V clamping - making it preferred for space-constrained automotive and industrial PCBs requiring validated reliability.

FAQ
What is the exact breakdown voltage tolerance for TPSMA16A61HE3J_B/H?
The TPSMA16A61HE3J_B/H has a guaranteed breakdown voltage range of 15.2 V (minimum) to 16.8 V (maximum) at 1.0 mA test current, with 16.0 V nominal value. This ±5% tolerance is verified per ANSI/IEEE C62.35 and applies at TA = 25 °C; actual VBR shifts predictably with temperature using αT = 0.078 %/°C.
Is TPSMA16A61HE3J_B/H AEC-Q101 qualified?
Yes, TPSMA16A61HE3J_B/H is AEC-Q101 qualified. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, validated for automotive applications including temperature cycling, highly accelerated life testing (HALT), and ESD robustness per AEC specification.
What does the "61" in TPSMA16A61HE3J_B/H signify?
The "61" in TPSMA16A61HE3J_B/H is a revision code indicating the specific manufacturing lot and process iteration per Vishay's internal documentation. It corresponds to the "_X" placeholder in the ordering nomenclature (e.g., Base P/NHE3_X), where "61" reflects the latest qualified revision as of the 23-Jan-2024 datasheet revision.
Can TPSMA16A61HE3J_B/H be used in bidirectional configurations?
No, TPSMA16A61HE3J_B/H is unidirectional only. Its internal structure supports clamping of positive transients only (cathode to protected line, anode to ground). For bidirectional protection, a separate device such as TPSMA16CA or dual-diode array must be used - TPSMA16A61HE3J_B/H lacks symmetrical breakdown capability.
What is the maximum allowable PCB pad size for TPSMA16A61HE3J_B/H per datasheet?
The datasheet specifies that thermal and electrical ratings assume mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads attached to each terminal. Using smaller pads reduces power dissipation capability and increases junction temperature; full 400 W PPPM and 1.0 W PD ratings are only valid with this minimum pad layout.
