Product details
Overview
TPSMB11AHM3_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 and signal lines. It features 11.0 V nominal breakdown voltage (VBR), 9.4 V stand-off voltage (VWM), 38.5 V maximum clamping voltage at 15.6 A peak pulse current, 600 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMB11AHM3_A/I datasheet, TPSMB11AHM3_A/I pinout, TPSMB11AHM3_A/I application, or TPSMB11AHM3_A/I equivalent, this page delivers verified electrical parameters, thermal limits (TJ = –65 °C to +185 °C), mechanical package data, real-world protection scenarios, and qualified alternative parts for robust circuit design and supply chain continuity.
Technical Context
This TVS diode operates as a unidirectional clamping device with fast response time and low incremental surge resistance, enabling effective suppression of transient overvoltages before sensitive downstream components are damaged. Its junction passivated anisotropic rectifier technology ensures stable performance under high-temperature stress and repetitive surge conditions.
The device is rated for 75 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), exhibits 0.067 %/°C temperature coefficient of VBR, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, supporting automated SMT assembly in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 10.5 V / 11.0 V / 11.6 V - defines precise voltage threshold at which clamping initiates under 1 mA test current |
| VWM | 9.4 V - maximum continuous reverse operating voltage without significant leakage; sets safe DC bias margin |
| VC @ IPPM | 38.5 V at 15.6 A - clamped voltage during worst-case 10/1000 µs surge; determines protected circuit's peak stress level |
| PPPM | 600 W - peak pulse power handling capability; enables robust protection against IEC 61000-4-5 Level 4 surges |
| TJ max. | +185 °C - extended junction temperature rating supports under-hood automotive and high-ambient industrial deployment |
| IR @ VWM | 2 µA - ultra-low reverse leakage at stand-off voltage preserves system power integrity in battery-powered applications |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 0.220" × 0.130" footprint and cathode band marking |
Pinout & Package
TPSMB11AHM3_A/I is a two-terminal unidirectional TVS diode in SMB (DO-214AA) package. The cathode is marked by a color band on the body; the anode is the unmarked end. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR |
| Anode (unbanded end) | Reference/ground return path | Typically tied to system ground or low-impedance return plane; completes clamping current loop |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | Same VBR (10.5–11.6 V), identical SMB package, but rated for 600 W with 10/1000 µs waveform and not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated | Select SMBJ11A for cost-sensitive non-automotive applications requiring same clamping performance without qualification overhead |
| TPSMB11AHM3_A/H | Identical electrical and thermal specs; differs only in packaging-7" tape-and-reel (750 pcs) vs. 13" reel (3200 pcs) for TPSMB11AHM3_A/I | No functional difference; choice driven by production volume, SMT feeder compatibility, and inventory planning | Choose TPSMB11AHM3_A/H for low-volume prototyping or small-batch builds; TPSMB11AHM3_A/I suits high-volume automated assembly |
Compared with SMBJ11A and TPSMB11AHM3_A/H, the TPSMB11AHM3_A/I provides guaranteed AEC-Q101 qualification and halogen-free compliance in high-volume 13" reel format-making it the preferred choice for Tier 1 automotive suppliers and long-lifecycle industrial programs requiring traceable, qualified components.

FAQ
What is the breakdown voltage tolerance of TPSMB11AHM3_A/I?
The TPSMB11AHM3_A/I has a specified breakdown voltage range of 10.5 V (minimum) to 11.6 V (maximum) at 1 mA test current, with 11.0 V as the nominal value. This ±5% tolerance ensures consistent clamping behavior across production lots and supports reliable design margins for 12 V automotive and industrial systems. The parameter is measured per ANSI/IEEE C62.35 standards and validated during 100% production testing.
Is TPSMB11AHM3_A/I suitable for bidirectional transient protection?
No, TPSMB11AHM3_A/I is a unidirectional TVS diode and is not suitable for bidirectional protection. It clamps only positive-going transients relative to its cathode terminal and conducts no significant current for negative excursions beyond its forward voltage (~3.5 V at 50 A). For bidirectional applications such as AC lines or symmetric data buses, a dedicated bidirectional part like SMBJ11CA must be used instead of TPSMB11AHM3_A/I.
Does TPSMB11AHM3_A/I require a heatsink in typical applications?
No, TPSMB11AHM3_A/I does not require an external heatsink in standard surge protection applications because it handles energy in short-duration pulses (e.g., 10/1000 µs), not continuous power dissipation. Its thermal design relies on PCB copper pad area (0.2" × 0.2") for transient heat spreading. The 185 °C maximum junction temperature and low thermal resistance enable safe operation without added thermal infrastructure in automotive and industrial layouts.
What is the meaning of the "HM3" suffix in TPSMB11AHM3_A/I?
"HM3" in TPSMB11AHM3_A/I denotes Vishay's halogen-free, RoHS-compliant, and AEC-Q101-qualified variant. The "H" indicates halogen-free molding compound; "M3" confirms compliance with JESD201 Class 2 whisker resistance and full automotive qualification. This distinguishes it from the HE3 variant (RoHS-compliant and AEC-Q101 qualified but not halogen-free) and ensures alignment with strict environmental and reliability mandates for Tier 1 automotive supply chains.
Can TPSMB11AHM3_A/I be used in place of TPSMB11AHE3_A/I?
Yes, TPSMB11AHM3_A/I can replace TPSMB11AHE3_A/I in most designs because both share identical electrical specifications (VBR, VC, PPPM, TJ), mechanical dimensions, and AEC-Q101 qualification. The sole difference is that HM3 uses halogen-free packaging while HE3 does not. If halogen-free compliance is required (e.g., for EU automotive programs), TPSMB11AHM3_A/I is the appropriate selection; otherwise, either variant functions equivalently in circuit.
