Product details
Overview
TPSMB15AHE3/52T from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 28.3 A peak pulse current (IPPM), and 21.2 V maximum clamping voltage (VC) - enabling robust protection of MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the TPSMB15AHE3/52T datasheet, TPSMB15AHE3/52T pinout, TPSMB15AHE3/52T application, or TPSMB15AHE3/52T equivalent, this page delivers verified electrical parameters, SMB (DO-214AA) package details, AEC-Q101 qualification status, thermal derating curves, and direct alternative part comparisons - all grounded in Vishay's official 88406 document revision 23-Jan-2024.
Technical Context
The TPSMB15AHE3/52T employs passivated anisotropic rectifier technology to achieve stable junction behavior up to 185 °C, supporting high-reliability automotive environments. Its unidirectional polarity and low incremental surge resistance ensure precise clamping with minimal overshoot during fast-rising transients.
Rated for 600 W peak pulse power at 10/1000 µs waveform and 75 A non-repetitive forward surge current (IFSM), it operates across –65 °C to +185 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 14.3 / 15.0 / 15.8 V - ensures reliable turn-on above system operating voltage while avoiding false triggering |
| VWM | 12.8 V - maximum continuous reverse working voltage compatible with 12 V nominal rail systems |
| VC @ IPPM | 21.2 V - clamps transient energy to safe levels for downstream 24 V tolerant components |
| IPPM | 28.3 A - supports suppression of high-current transients from inductive loads like solenoids or motors |
| PPPM | 600 W - delivers standardized surge handling per IEC 61000-4-5 (10/1000 µs) without thermal runaway |
| TJ max | +185 °C - enables under-hood automotive placement and long-term reliability in thermally stressed PCB areas |
| Leakage @ VWM | 1 µA - negligible standby current draw preserving battery life in always-on circuits |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Clamping |
|---|---|
Use Scenario: Suppressing load-dump and alternator ripple transients on 12 V battery-fed ECUs and body control modules. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between power rail and chassis ground to clamp positive-going surges above 15 V. Use Value: Prevents damage to MCU power supplies and CAN transceivers by limiting peak voltage to 21.2 V at 28.3 A surge current. |
Use Scenario: Protecting analog output lines (e.g., 4–20 mA current loops) from ESD and cable discharge events in factory automation sensors. IC Role / Device Role / Timing Role: Standoff-connected TVS on signal line to ground, leveraging 1 µA leakage to avoid loading precision current sources. Use Value: Maintains signal integrity with sub-100 ps response time and clamps 8 kV contact ESD to <25 V at the sensor IC input pin. |
| Motor Drive Gate Protection | Telecom DC Power Input Stage |
Use Scenario: Shielding high-side N-channel MOSFET gate drivers from inductive kickback during PWM switching in BLDC inverters. IC Role / Device Role / Timing Role: TVS placed between gate and source to clamp negative-going spikes below –0.7 V and positive surges above 15 V. Use Value: Prevents gate oxide breakdown using 21.2 V clamping and 185 °C junction capability for sustained motor control thermal environments. |
Use Scenario: Safeguarding primary DC/DC converter inputs against lightning-induced surges on outdoor telecom base station power feeds. IC Role / Device Role / Timing Role: First-line transient suppressor on 48 V input rail before bulk capacitance and upstream fuse. Use Value: Absorbs 600 W surge energy per event with 28.3 A IPPM, reducing stress on downstream TVS arrays and enabling smaller secondary protection stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Same VBR (14.3–15.8 V), lower PPPM = 400 W, SMA package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; not AEC-Q101 qualified; unsuitable for under-hood automotive use | Select when board space is constrained and surge duty cycle is light (<0.001 %), but avoid for automotive or high-reliability industrial designs. |
| SMCJ15A | Same VBR, higher PPPM = 1500 W, SMC package (larger, higher thermal inertia), same AEC-Q101 option available (HE3) | Supports repetitive surges and longer-duration transients; requires larger PCB pad area and higher mounting copper | Choose when protecting high-power motor drives or telecom rectifiers where 600 W is insufficient; verify layout clearance for SMC outline. |
Compared with SMAJ15A and SMCJ15A, the TPSMB15AHE3/52T delivers optimal balance of automotive qualification, 600 W surge capacity, and SMB footprint - making it ideal for space-constrained ECU power rails where AEC-Q101 compliance and thermal resilience are mandatory.

FAQ
What is the exact breakdown voltage range for TPSMB15AHE3/52T?
The TPSMB15AHE3/52T has a guaranteed breakdown voltage range of 14.3 V (minimum) to 15.8 V (maximum) at 1 mA test current, with 15.0 V nominal. This range is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88406, ensuring predictable clamping onset across production lots and temperature extremes up to 185 °C.
Is TPSMB15AHE3/52T qualified for automotive applications?
Yes, TPSMB15AHE3/52T is AEC-Q101 qualified - explicitly stated in the "MECHANICAL DATA" section of Vishay's 88406 datasheet. The HE3 suffix denotes RoHS-compliant, AEC-Q101 qualified construction, validated for high-temperature operation (TJ = 185 °C), humidity resistance, and mechanical shock per automotive reliability standards.
What does the "HE3/52T" suffix indicate in TPSMB15AHE3/52T?
The "HE3" suffix identifies the part as RoHS-compliant and AEC-Q101 qualified; "52T" specifies the tape-and-reel packaging: 7" diameter reel, 750-unit quantity, plastic carrier tape per EIA-481-D. This matches Vishay's ordering code convention in the "ORDERING INFORMATION" table of Document 88406.
How does TPSMB15AHE3/52T compare to TPSMB15AHE3/A?
TPSMB15AHE3/52T and TPSMB15AHE3/A share identical electrical specifications and AEC-Q101 qualification. The difference lies solely in packaging: "52T" denotes 7" reel (750 pcs), while "A" indicates a different reel size or orientation per Vishay's internal coding - both are functionally and electrically interchangeable in circuit design and layout.
What is the maximum clamping voltage of TPSMB15AHE3/52T at rated surge current?
The TPSMB15AHE3/52T clamps to a maximum of 21.2 V at its rated peak pulse current of 28.3 A (10/1000 µs waveform), as specified in the "ELECTRICAL CHARACTERISTICS" table of Document 88406. This value is measured under standardized conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
