Product details
Overview
TPSMA16AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SMA (DO-214AC) package, designed to protect sensitive electronics against voltage transients from inductive switching and lightning. It features 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 17.8 V clamping voltage at 5.0 A IPPM, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMA16AHM3_B/I datasheet, TPSMA16AHM3_B/I pinout, TPSMA16AHM3_B/I application, or TPSMA16AHM3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification for automotive use, MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction with matte tin-plated leads.
Technical Context
The TPSMA16AHM3_B/I uses passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its junction passivation enables reliable operation at TJ = 185 °C, meeting stringent automotive reliability requirements under AEC-Q101 stress testing.
It delivers fast response time and excellent clamping capability with a 10/1000 µs waveform, rated for 400 W non-repetitive peak pulse power at 25 °C and derated linearly above that ambient. The device exhibits a typical VBR temperature coefficient of +0.078 %/°C, enabling predictable voltage shift across operating temperature ranges.
Key Specifications

Pinout & Package
TPSMA16AHM3_B/I is housed in the SMA (DO-214AC) surface-mount package, featuring a cathode band marking on one end. The device has two terminals: anode and cathode, with polarity indicated by the molded band. Mounting requires minimum recommended copper pad layout (0.2" × 0.2") per terminal for thermal and mechanical reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 (16.0 V), but lower PPPM = 400 W (same rating), non-AEC-Q101, no halogen-free option | Not qualified for automotive; limited to commercial/industrial use where AEC-Q101 is not mandated | Select SMAJ16A only if AEC-Q101 and halogen-free compliance are unnecessary and cost is prioritized |
| TPSMA16AHE3_B/I | Identical electrical specs and package, but RoHS-compliant with lead-free plating and AEC-Q101 qualification; lacks halogen-free certification | Acceptable for automotive use but does not meet halogen-free material categorization (per Vishay doc 99912) | Choose TPSMA16AHE3_B/I when halogen-free content is not required but AEC-Q101 and RoHS are mandatory |
Compared with SMAJ16A and TPSMA16AHE3_B/I, the TPSMA16AHM3_B/I uniquely combines AEC-Q101 qualification, halogen-free construction, and RoHS compliance-making it the only option among the three certified for high-reliability automotive systems requiring full material compliance.

FAQ
What is the clamping voltage of the TPSMA16AHM3_B/I at its rated peak pulse current?
The TPSMA16AHM3_B/I has a maximum clamping voltage (VC) of 22.0 V at 5.0 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during transient events. The TPSMA16AHM3_B/I maintains this clamping performance across its full operating temperature range, supporting design margin calculations for downstream components like microcontrollers and MOSFETs.
Is the TPSMA16AHM3_B/I qualified for automotive applications?
Yes, the TPSMA16AHM3_B/I is AEC-Q101 qualified and explicitly designated for automotive use, as confirmed by Vishay's ordering code suffix "HM3" and documentation. It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). The TPSMA16AHM3_B/I also supports junction temperatures up to +185 °C, making it suitable for under-hood and powertrain-related applications where thermal robustness is critical.
What does the "HM3" suffix indicate in TPSMA16AHM3_B/I?
The "HM3" suffix in TPSMA16AHM3_B/I denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction per Vishay's material categorization standard (doc 99912). It distinguishes this variant from the "HE3" version, which is RoHS- and AEC-Q101-compliant but not halogen-free. The "B/I" portion specifies revision B and 13-inch tape-and-reel packaging (7500 units per reel), ensuring consistency in manufacturing and assembly logistics for the TPSMA16AHM3_B/I.
How does the TPSMA16AHM3_B/I compare to the TPSMA16AHE3_B/I in terms of compliance?
The TPSMA16AHM3_B/I adds halogen-free certification to the same AEC-Q101 qualification and RoHS compliance found in the TPSMA16AHE3_B/I. Both share identical electrical parameters and SMA package, but only the HM3 version meets Vishay's halogen-free material requirements (per doc 99912), making the TPSMA16AHM3_B/I the preferred choice for automotive OEMs mandating full material declarations. Neither part is pin-compatible with non-TPSMA series devices.
What is the maximum reverse leakage current of the TPSMA16AHM3_B/I at its stand-off voltage?
The TPSMA16AHM3_B/I exhibits a maximum reverse leakage current (IR) of 1.0 µA at its 13.6 V stand-off voltage (VWM) and 25 °C ambient temperature. At elevated temperature (TJ = 150 °C), leakage increases to 1000 µA - a specified worst-case value used for thermal design margining. This low-leakage behavior ensures minimal power loss and signal interference in always-on sensor and communication circuits using the TPSMA16AHM3_B/I.
