Product details
Overview
TPSMB10AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive and lightning-induced transients on power and signal lines. It features 10 V breakdown voltage (VBR = 9.5–10.5 V at 1 mA), 8.55 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 14.5 A peak pulse current (IPPM), and 41.4 V maximum clamping voltage (VC) - deployed in automotive sensor protection and industrial I/O interfaces.
For engineers reviewing the TPSMB10AHM3_A/H datasheet, TPSMB10AHM3_A/H pinout, TPSMB10AHM3_A/H application, or TPSMB10AHM3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low incremental surge resistance, and halogen-free RoHS-compliant construction per HM3 suffix.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, triggering when reverse voltage exceeds VBR to divert surge current away from sensitive components. Its passivated anisotropic rectifier structure ensures stable breakdown behavior under repetitive transients and high-temperature operation up to 185 °C.
The device uses a silicon avalanche junction optimized for fast response (<1 ns) and low clamping ratio (VC/VBR ≈ 4.14), with thermal derating defined per Fig. 2 and validated per JEDEC J-STD-020 MSL Level 1 (260 °C peak reflow). It is rated for 75 A non-repetitive forward surge (8.3 ms half-sine) and exhibits <5 µA reverse leakage at VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 9.5–10.5 V at 1 mA - defines precise conduction threshold for transient suppression |
| Stand-off Voltage VWM | 8.55 V - maximum continuous reverse voltage before leakage exceeds 5 µA |
| Clamping Voltage VC | 41.4 V at 14.5 A (10/1000 µs) - limits voltage seen by downstream ICs during surge |
| Peak Pulse Power PPPM | 600 W - sustains single high-energy transients without failure under standard waveform |
| Junction Temperature Range | −65 °C to +185 °C - enables use in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling and HTRB |
| Package | SMB (DO-214AA) - surface-mount footprint compatible with automated assembly and 0.2" × 0.2" copper pad layout |
Pinout & Package
TPSMB10AHM3_A/H is a two-terminal unidirectional TVS diode in SMB (DO-214AA) package. The cathode is marked by a color band; terminals are matte tin-plated and solderable per J-STD-002 and JESD 22-B102. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads at each terminal for thermal and surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage |
| Anode | Reference/return path | Typically tied to system ground or lower-potential rail; completes clamping current path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VWM (8.55 V) and VC (41.4 V), but lower PPPM (400 W); SMA package (smaller thermal mass) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost or board space is critical and surge energy remains below 400 W |
| TPSMB10AHM3_A/I | Identical electrical specs and construction; differs only in tape-and-reel packaging (3200 pcs vs. 750 pcs per reel) | No functional difference; same automotive qualification and reliability testing | Choose based on production volume and SMT line feeder compatibility |

FAQ
What is the maximum clamping voltage of the TPSMB10AHM3_A/H at its rated peak pulse current?
The TPSMB10AHM3_A/H has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current of 14.5 A under the standard 10/1000 µs waveform. This value is measured per Figure 3 in the Vishay datasheet 88406 and reflects the upper limit of voltage imposed on protected circuitry during surge events. The TPSMB10AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is the TPSMB10AHM3_A/H qualified for automotive applications?
Yes, the TPSMB10AHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3", which denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias (HTRB), and accelerated moisture resistance to meet automotive reliability standards. The TPSMB10AHM3_A/H is explicitly intended for under-hood and chassis-mounted electronics.
What does the "HM3" suffix indicate in TPSMB10AHM3_A/H?
The "HM3" suffix in TPSMB10AHM3_A/H identifies the device as halogen-free, RoHS-compliant, and AEC-Q101 qualified - distinguishing it from the HE3 variant (RoHS-compliant and AEC-Q101 qualified but not halogen-free). The "_A/H" denotes revision A in 7" diameter plastic tape-and-reel packaging (750 pieces per reel). All TPSMB10AHM3_A/H units meet JESD 201 Class 2 whisker resistance and MSL Level 1 reflow requirements.
How does the TPSMB10AHM3_A/H compare to the TPSMB10AHE3_A/H in terms of compliance?
The TPSMB10AHM3_A/H is halogen-free, RoHS-compliant, and AEC-Q101 qualified, whereas the TPSMB10AHE3_A/H is RoHS-compliant and AEC-Q101 qualified but not halogen-free. Both share identical electrical specifications (VBR, VWM, VC, PPPM) and SMB packaging. The TPSMB10AHM3_A/H meets stricter environmental mandates such as China RoHS II and EU ELV, making it suitable for Tier 1 automotive supply chains requiring halogen-free materials.
What is the thermal derating behavior of the TPSMB10AHM3_A/H above 25 °C ambient?
The TPSMB10AHM3_A/H follows the derating curve in Figure 2 of Vishay document 88406: its peak pulse power decreases linearly from 100% at 25 °C to approximately 50% at 125 °C and to zero at 175 °C. This derating applies to both PPPM and IPPM. The TPSMB10AHM3_A/H retains full functionality up to 185 °C junction temperature, but sustained surge duty requires thermal design that limits TJ per the curve to maintain specified clamping performance.
