Product details
Overview
TPSMB16AHE3/5BT 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 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage at 26.7 A peak pulse current, 600 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - used in automotive sensor protection and industrial power rail surge suppression.
For engineers reviewing the TPSMB16AHE3/5BT datasheet, TPSMB16AHE3/5BT pinout, TPSMB16AHE3/5BT application, or TPSMB16AHE3/5BT equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HE3 suffix), MSL Level 1 rating, 185 °C thermal capability, and 26.7 A IPPM with low clamping ratio (VC/VBR ≈ 1.41).
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-reliability transient suppression. Its junction design delivers stable VBR over temperature (αT = 0.078 %/°C) and low incremental surge resistance, enabling consistent clamping performance under repetitive 10/1000 µs surges at 0.01 % duty cycle.
Rated for 75 A non-repetitive forward surge (8.3 ms half-sine), it maintains <3.5 V forward voltage at 50 A and supports soldering per J-STD-002/JESD 22-B102 with matte tin-plated leads. The cathode band denotes polarity, and the device meets UL 94 V-0 flammability requirements in its SMB molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - ensures reliable triggering above system operating voltage while avoiding false trips |
| VWM | 13.6 V - maximum continuous reverse working voltage compatible with 12 V nominal systems |
| VC @ IPPM | 22.5 V - clamps transients to safe levels for downstream 24 V-rated ICs and MOSFETs |
| IPPM | 26.7 A - peak surge current handling capacity under standardized 10/1000 µs waveform |
| PPPM | 600 W - robust energy absorption for automotive load-dump and ESD-related transients |
| TJ max. | +185 °C - enables operation in under-hood automotive environments and high-power industrial enclosures |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct orientation in circuit |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case with UL 94 V-0 rating; cathode indicated by color band; terminals are matte tin-plated for reliable solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during forward conduction or transient clamping | Connected to protected line (e.g., 12 V rail); must be placed upstream of sensitive loads |
| Cathode | Current exit during clamping; referenced to ground or lower potential | Connected to ground or return path; polarity marking critical for unidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns |
| Junction passivation technology | Minimizes leakage drift and improves long-term stability under thermal stress |
| Low clamping ratio (VC/VBR = 1.41) | Delivers tighter voltage margin between trigger and clamp, enhancing system-level protection margin |
| 185 °C TJ capability | Supports placement near heat sources (e.g., power converters) without derating penalties |
Applications
| Automotive Sensor Protection | Industrial Power Rail Clamping |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses.

IC Role / Device Role: Unidirectional TVS on differential pair or bias rail to clamp common-mode transients while preserving signal integrity. Use Value: Low capacitance (<100 pF typical) and fast response minimize signal distortion on high-speed telecom links up to 100 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Same SMB package, identical VBR/VC specs, but not AEC-Q101 qualified; MSL Level 1, RoHS-compliant | Targeted at industrial/commercial use; lacks automotive qualification documentation and test reports | Select SMBJ16A when AEC-Q101 is not required and cost optimization is prioritized |
| TPSMB16AHM3/5BT | Halogen-free variant of same base part; identical electrical specs and AEC-Q101 qualification; differs only in material composition | Required where halogen-free compliance is mandated (e.g., EU public infrastructure projects) | Choose TPSMB16AHM3/5BT when halogen-free materials are specified in procurement requirements |
Compared with SMBJ16A and TPSMB16AHM3/5BT, the TPSMB16AHE3/5BT uniquely combines AEC-Q101 qualification, RoHS compliance, and standard material formulation - making it optimal for Tier-1 automotive subsystems requiring full traceability and qualification evidence without halogen-free overhead.

FAQ
What is the breakdown voltage tolerance for TPSMB16AHE3/5BT?
The TPSMB16AHE3/5BT has a breakdown voltage (VBR) range of 15.2 V (min) to 16.8 V (max) at 1 mA test current, with 16.0 V nominal. This ±5% tolerance ensures predictable triggering behavior across production lots while maintaining compatibility with 12 V system margins and 24 V rail headroom requirements.
Is TPSMB16AHE3/5BT suitable for bidirectional transient protection?
No, TPSMB16AHE3/5BT is unidirectional only - it clamps positive transients relative to ground and conducts in forward bias during overvoltage events. For bidirectional protection, a separate device such as SMAJ16CA or a dual-diode configuration is required; using TPSMB16AHE3/5BT in reverse orientation will not provide clamping.
Does TPSMB16AHE3/5BT require derating at elevated ambient temperatures?
Yes - the peak pulse power (PPPM) and peak pulse current (IPPM) must be derated above TA = 25 °C per Figure 2 in the datasheet. At 125 °C ambient, TPSMB16AHE3/5BT retains approximately 50% of its 600 W rating, reflecting its thermal design for high-TJ operation up to +185 °C.
What does the "HE3" suffix indicate in TPSMB16AHE3/5BT?
The "HE3" suffix denotes RoHS-compliant construction and AEC-Q101 qualification. It confirms that TPSMB16AHE3/5BT has passed automotive-grade stress tests including HTGB, H3TRB, and temperature cycling, and uses matte tin-plated leads compliant with JESD 201 Class 2 whisker resistance.
Can TPSMB16AHE3/5BT be used in place of TPSMB16AHM3/5BT?
Yes, TPSMB16AHE3/5BT and TPSMB16AHM3/5BT share identical electrical specifications, package, and AEC-Q101 qualification - differing only in halogen content (HE3 is standard; HM3 is halogen-free). Substitution is electrically seamless, but HM3 must be selected if halogen-free compliance is contractually required.
