Product details
Overview
TPSMB30-10HE3/5BT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 30 V breakdown voltage (VBR = 28.5–31.5 V), 25.6 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 engine control units, industrial PLC I/O protection, and telecom power supply input stages.
For engineers reviewing the TPSMB30-10HE3/5BT datasheet, TPSMB30-10HE3/5BT pinout, TPSMB30-10HE3/5BT application, or TPSMB30-10HE3/5BT equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, TJ = 185 °C junction rating, and clamping performance under repetitive 0.01% duty cycle surges.
Technical Context
This TVS diode operates as a voltage-clamping protection device in parallel with sensitive circuitry, conducting only when reverse voltage exceeds its breakdown threshold. Its passivated anisotropic rectifier structure ensures stable VBR drift (αT = 0.088 %/°C) and low incremental surge resistance across -65 °C to +185 °C operating range.
It delivers fast response (<1 ns) to transient events and maintains reliable clamping under high-temperature conditions, meeting MSL Level 1 reflow requirements (260 °C peak) and JESD201 Class 2 whisker resistance - critical for automotive under-hood and industrial control environments where thermal cycling and long-term reliability are mandated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V - defines precise conduction onset; enables accurate overvoltage margining against 24 V nominal systems |
| VWM | 25.6 V - maximum continuous reverse working voltage; ensures no leakage during normal 24 V rail operation |
| VC @ IPPM | 41.4 V - clamped voltage at 14.5 A surge; limits downstream IC stress below 45 V absolute max ratings |
| PPPM | 600 W - peak pulse power handling (10/1000 µs); sustains multiple ISO 7637-2 Pulse 1/2b/5a transients |
| TJ max. | +185 °C - extended junction temperature rating; supports placement near hot components in automotive ECUs |
| Polarity | Unidirectional - protects against negative-going transients only; requires correct cathode orientation toward protected line |
| Package | SMB (DO-214AA) - standardized SMT footprint; compatible with automated assembly and IPC-7351B land patterns |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case with matte tin-plated leads. Cathode indicated by color band. Complies with UL 94 V-0 flammability rating and J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during transient conduction |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 24 V rail or sensor output); blocks VWM in normal operation, conducts above VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD47 |
| Junction temperature capability | TJ = 185 °C enables use in under-hood modules without derating in ambient up to +125 °C |
| Clamping ratio (VC/VBR) | 1.38 - low ratio ensures minimal overvoltage overshoot during fast transients |
| MSL Level 1 rating | Supports standard Pb-free reflow profiles up to 260 °C peak without moisture-induced failure |
| Low leakage at VWM | IR ≤ 1 μA at 25.6 V - avoids parasitic loading on high-impedance sensor or bias networks |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply inputs of engine control units (ECUs) against load dump and alternator ripple. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed directly at connector entry point, shunting surge energy to chassis ground. Use Value: Limits transient voltage to ≤41.4 V, preventing damage to downstream DC-DC converters and microcontrollers rated for 45 V max input. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in factory automation systems exposed to relay coil switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS connected between sensor output line and ground, suppressing negative-going spikes. Use Value: Maintains signal integrity with <1 μA leakage at 25.6 V, avoiding offset errors in 4–20 mA loop circuits. |
| Telecom DC Power Input Protection | Motor Drive Gate Driver Protection |
Use Scenario: Input stage protection for PoE-powered network switches subjected to lightning-induced surges on 48 V DC feed lines. IC Role / Device Role / Timing Role: Primary clamping device on DC input before bulk capacitance and upstream DC-DC controller. Use Value: Withstands 600 W pulses (10/1000 µs) and meets IEC 61000-4-5 Level 3 immunity requirements. | Use Scenario: Shielding high-side gate drivers in BLDC motor inverters from Miller-induced voltage spikes during MOSFET switching. IC Role / Device Role / Timing Role: TVS placed between gate and source of power MOSFET, clamping dv/dt-induced overshoot. Use Value: Fast <1 ns response and low VC prevent false turn-on and gate oxide overstress in 600 V Si MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Same VBR range (28.5–31.5 V), identical SMB package, but not AEC-Q101 qualified; lower TJ max. (150 °C) | Acceptable for commercial/industrial use only; unsuitable for automotive under-hood deployment | Select when AEC-Q101 compliance is not required and cost sensitivity outweighs extended temperature needs |
| TPSMB30AHM3 | Identical electrical specs and AEC-Q101 qualification; halogen-free molding compound vs. RoHS-compliant HE3 variant | Required for strict environmental compliance programs (e.g., EU automotive Tier 1 sourcing) | Choose HM3 when halogen-free material declaration is mandatory per OEM specification |
Compared with SMBJ30A and TPSMB30AHM3, the TPSMB30-10HE3/5BT provides verified AEC-Q101 qualification and RoHS compliance in a standard HE3 tape-and-reel format, enabling drop-in use in automotive production without requalification - while differing from HM3 only in halogen content, not performance.

FAQ
What is the exact breakdown voltage range for TPSMB30-10HE3/5BT?
The TPSMB30-10HE3/5BT has a guaranteed breakdown voltage (VBR) range of 28.5 V to 31.5 V at 1 mA test current, with a nominal value of 30.0 V. This range is measured per ANSI/IEEE C62.35 standards and remains stable across temperature due to its 0.088 %/°C temperature coefficient - critical for consistent protection behavior in varying ambient conditions.
Is TPSMB30-10HE3/5BT AEC-Q101 qualified?
Yes, TPSMB30-10HE3/5BT 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 electrostatic discharge per JESD22-A114. This qualification is documented in Vishay's official compliance reports for the TPSMB family.
What does the "-10HE3/5BT" suffix indicate in TPSMB30-10HE3/5BT?
The "-10HE3/5BT" suffix specifies packaging and revision: "10" indicates the preferred ordering variant within the TPSMB30A family; "HE3" confirms RoHS compliance and AEC-Q101 qualification; "5BT" denotes 7-inch tape-and-reel packaging with 750 units per reel, per Vishay's standard ordering nomenclature for SMB devices.
Can TPSMB30-10HE3/5BT replace TPSMB30AHE3 in existing designs?
Yes, TPSMB30-10HE3/5BT is functionally and mechanically identical to TPSMB30AHE3 - both share the same electrical specifications, SMB (DO-214AA) package, AEC-Q101 qualification, and RoHS compliance. The "-10" designation reflects Vishay's internal revision or preferred part number alignment, not a functional change; no layout or schematic modifications are needed.
What is the maximum clamping voltage of TPSMB30-10HE3/5BT under surge conditions?
The TPSMB30-10HE3/5BT exhibits a maximum clamping voltage (VC) of 41.4 V at its rated peak pulse current of 14.5 A (10/1000 µs waveform). This value is measured per JEDEC standards and ensures protected circuitry remains within safe operating limits - for example, preserving 45 V-rated DC-DC controllers during ISO 7637-2 Pulse 5a events.
